Computer not assigning itself IPv4 address after startup

This is a rather fustrating problem I've been dealing with as of the last few weeks.  I somewhat have a solution, but it is not one I can continue to do for several days at a time.  What is happening is I am getting the error "Wi-Fi doesn't have a valid IP configuration".  I've had windows10 for quite a while, and I know many people had this problem when they first got win10, but none of the solutions I've found on the internet have fixed my problem. (example of most common troubleshooting I am finding: https://www.drivereasy.com/knowledge/wifi-doesnt-have-a-valid-ip-configuration-on-windows-10-solved/).  Below are the most key points to my current experience with this error.

  • The problem exists only on one computer, not on any other computer running windows10 or any other opperating system.  Desktops, all in ones, laptops, smartphones, tablets, gaming systems, all of them still connect to the internet with absolutely no problems
  • The affected computer can still connect to the home network without any issues.  It logs in fine, detects and communicates with other computers, but cannot obtain internet access.
  • The problem exists both on wifi AND ethernet.  Plugging the computer directly to the modem exhibits the exact same behavior
  • Resetting the modem and the router does not correct the problem
  • Consolting the router shows my computer as having an unknown IP adress.  Further consolting the effected computer's properties shows no info assigned for IPv4.  What is shown is as follows:

SSID: (private info)

Protocol: 802.11n

Security type: WPA2-Personal

Network Band: 2.4GHz

Network channel: 4

IPV6: DNS servers: fec0:0:0:fff:1%1  (following 2 other entries, with 1% changed to 2% and 3%)

Manufacturer: Qualcom Communications Inc>

Description: Qualcom Atheros QCA61x4A Wireless network Adaptor

Driver Version: 4.0.0.262

Physical address (MAC): (will provide if needed)

  • Manually assigning an IPv4 address either does not fix the problem or I am unsure of what is the correct info to assign for my computer
  • my computer's drivers are fully up to date as of the time of this message
  • I have uninstalled and reinstalled programs attempting to diagnose if any of these are the problem, none seem to be at fault, nor can I identify any program or windows update occuring that might be responsible for the trouble (though if windows is doing more stealth updates I may be unaware of them)
  • Notably uninstalling and resinstalling Steam (game client) and prevenging auto-startup of the program allowed uninhibited internet access for 3 days, but the problem has returned again.  Steam has had no updates since the uninstall, nor has its settings changed.
  • Performing a system restore WILL restore internet access

There-in hits the most unusual nature of this problem - with no other adjustments to the computer, activating the system restore thus far has fixed the problem.  I've begun resorting to implementing a manual restore point to my computer any time I make adjustments to the computer or a program, and that restores my internet once I revert to one of these points.  However this is a long process and absolutely not something I can continue to do every day I need to use my computer, especialy when I am waking up early in the morning and need my computer before work.  Everything on my end points back to that IPv4 address that the computer is somehow losing the ability to assign for itself, and that my internet cannot provide access to without it.  How can we fix this problem?

The router assigns the IP address via DHCP.

Make sure that everything is set to automatic under IPv4.

In a cmd window enter the following and report back any error

ipconfig /renew

The router assigns the IP address via DHCP. Make sure that everything is set to automatic under IPv4. In a cmd window enter the following and report back any error ipconfig /renew

done as part of the troubleshooting exampled in my html address, does not work.  Everything is set to automatic, has no valid ipv4 assigned to it on startup until I've done a restore.

Did you get an error or did the command succeed?

If you do an

ipconfig /all

do you get IPv4 or IPv6 addresses?

Only happening to one PC and not the rest. Try rebooting modem.

Unplug power 30 seconds, plug power in. when connected to internet, restart all PC's and devices connected to your network.

You can also go to your network adapter settings or in device manager and delete all the drivers or just delete the network adapters, restart PC, it will detect and reinstall all network adapter drivers. restart PC again. Then do the above step rebooting modem.

Please read the ENTIRE topic before responding.  Bullet point 4, modem reset does not fix the problem.

>>>>Please read the ENTIRE topic before responding<<<?????????????

Don't ask for help and then be rude. I posted another option for you in same post.

Did ya check your adapter and the IPV4.

ipv4 address assignment greyed out

Did you check the drivers in device manager.

You have to select the view tab and show hidden to show all network adapters

Then see if the drivers are installed and no red or yellow flags exist.

ipv4 address assignment greyed out

Next, did this start after the recent cumulative windows update?????

Next, happens with Wi-Fi and Ethernet. Also beside checking the IPV4 for Ethernet, check your wireless adapter properties. Make sure one or both is not set to Static and on Automatic in IPV4 and IPV6 property settings

ipv4 address assignment greyed out

Open modem settings and maybe delete old devices connected in past. Some IP providers will only allow you so many devices at a time or in a lifetime.

It doesn't look like you've seen this one...

https://support.microsoft.com/en-us/help/929852/how-to-disable-ipv6-or-its-components-in-windows

I wouldn't disable it, but maybe click to " Prefer IPv4 over IPv6 in prefix policies ". See whether the problem is solved. Then click " Prefer IPv6 over IPv4 in prefix policies ", & see whether the problem remains solved. The process of switching back/forth sounds harmless & may jog a setting.

I pulled that out of...

http://www.thewindowsclub.com/enable-disable-ipv6-solve-internet-connectivity-problems

Don't ask for help and then be rude. I posted another option for you in same post. (1) Did ya check your adapter and the IPV4. (2) Did you check the drivers in device manager. (3) You have to select the view tab and show hidden to show all network adapters Then see if the drivers are installed and no red or yellow flags exist Next, did this start after the recent cumulative windows update????? (4) Next, happens with Wi-Fi and Ethernet. Also beside checking the IPV4 for Ethernet, check your wireless adapter properties. Make sure one or both is not set to Static and on Automatic in IPV4 and IPV6 property settings (5) Open modem settings and maybe delete old devices connected in past. Some IP providers will only allow you so many devices at a time or in a lifetime.

1) It's rude to only read part of the info and assume you know what the problem is and then offer support that has already been addressed, which wastes both our times. sadly this is expected results, and why I hesitated so many weeks to come to a forum in the first place. My reason for coming here isn't for random guesses, it's for someone to read the topic, realize they've seen this particular situation before and offer suggestion based on that experience that hasn't been tried yet.

2&5) Yes, that's how as the title says, I know I'm not getting an IPv4 address assigned to my computer, addressed in bullet 5 and 6, though I suppose I need to be more specific in saying it was originally automatic then I troubleshooted manually assigning it, if that was not clear.

3) Addressed in bullet 7, all drivers are up to date, again I guess needs to be more specific that no errors were spotted when I checked them for most recent driver.  What I did fail to specify was that I did delete and reinstall the drivers, but that was listed on the troubleshooting html that I liked as having done all of that already

4) Bullet 8, this means no update occurred unless ninja updated by windows without user knowledge or permission, as they love to do lately

5) This one I did fail to mention, done as part of troubleshooting from another source.  My modem allows for unlimited connections and I have already purged old computers.  My computer is also one of the first ones turned on in the day so if there was going to be spacing issues it would be for one of the later-activated devices, not my own.

  • Configure the Way RRAS Assigns IP Addresses to VPN Clients

You can use a DHCP server to assign IP addresses to VPN clients or you can configure an RRAS server to use a static pool of IP addresses for allocation to TCP/IP-based remote access and demand-dial connections. For more information, see RRAS and DHCP (https://go.microsoft.com/fwlink/?linkid=140605).

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

Open the RRAS MMC Snap-in .

Right-click the RRAS server name, and then click Properties . If you are using Server Manager, right-click Routing and Remote Access , and then click Properties .

On the Properties page, click the IPv4 tab.

Under IPv4 address assignment , click Static address pool .

Click Add .

In Start IP address , type a starting IP address.

Type either an ending IP address for the range in End IP address , or type the number of IP addresses in the range in Number of addresses , and then click OK .

Click OK , and then repeat steps 5 through 7 for as many ranges as you need to add.

Right-click the server name for which you want to create a static IP address pool, and then click Properties . If you are using Server Manager, right-click Routing and Remote Access , and then click Properties .

Under IPv4 address assignment , click Dynamic Host Configuration Protocol (DHCP) .

Click OK to save your changes.

Additional considerations

  • If the static IP address pool consists of ranges of IP addresses that are for a separate subnet, then you need to either enable an IP routing protocol on the remote access server computer or add static IP routes consisting of the {IP Address, Mask} of each range to the routers of the intranet. If the routes are not added, then remote access clients cannot receive traffic from resources on the intranet.
  • If the DHCP server is on the same subnet as the RRAS server, then you do not have to configure the DHCP relay agent. RRAS can find DHCP servers on the same subnet by using broadcast network packets.

[SOLVED] IP Address Not Set

By DeltaAlphaOscar January 22, 2020 in General Support

TL:DR: I can't get assigned a valid IP when starting UNRAID

This is my server build: PCPP link . I'm trying to run v6.8.1 (Trial version if that matters)

  • I'm not getting a valid IP, the only thing I'm getting is "IPv4 address: 169.254.222.203" and "IPv6 address: not set"
  • I'm getting the "FATAL:  Module bonding not found in directory /lib/modules/4.19.94-unRAID  Cannot find device "bond0" "
  • I was also getting some issues about finding directories, something something "/dev/disk/by-label/UNRAID"

Things I've done:

  • I've used the installer, so it should name and format my drive correctly. "UNRAID" and FAT32
  • Same installer
  • Same network cable and router
  • I haven't booted up anything else on the Node 304 but I was able to successfully check for BIOS update with the Ethernet plugged in to make sure I had up to date BIOS and that the internet was working.
  • I've tried every USB port (2.0 and 3.0)

:(

  • On thing that is weird is that it's a USB3.0 drive but it's only recognized on USB 2.0 port. Not just during boot, I'm talking through the Window's Explorer 

I'm a major noob just getting into the server world.

Can you get us the Diagnostics file?  If you have the GUI,   Tools    >>>   Diagnostics .  If you have only the console, login and type

the file will be written to the  logs folder/directory of the flash drive.  Post up the file in a new post.

Upon reading some other posts to try to troubleshoot this myself, I can access the GUI after logging in as root. This isn't my image, but it's what comes up after logging in.

In the 'start' menu, I had access to the console/terminal/command line but when typing in diagnostics, it says something along the lines of it not being a valid command. I'm not at (home) my server at the moment so I might not have the exact phraseology. 

After rereading your post  @Frank1940 , I may not have had the 's' at the end of diagnostics when I was troubleshooting last night...

7 hours ago, DeltaAlphaOscar said: I'm getting the "FATAL:  Module bonding not found in directory /lib/modules/4.19.94-unRAID  Cannot find device "bond0" "

This means something wrong with your usb flash boot device.  Either the volume label is not set to UNRAID or a file is missing or corrupted (bzmodules).  I suggest you try a different USB flash device or try re-install.  You can check volume label while plugged into PC.  Should also be FAT32 file system.

@Frank1940 , I tried to run the diagnostics and this time, I didn't get the invalid command comment because I remembered the "s". It seemingly did it's thing. BUT there wasn't a log folder created...

@limetech , I mentioned in my post that I tried using both the installer as well as doing it manually. It's always "UNRAID" and is always formatted FAT32.  The USB (DTSE9-G2) worked on the Dell I mentioned. This is what makes me think it should be fine(?). But alas I did manage to find another spare no-name USB last night and I got the same issues. Thoughts?

Make certain that you have the flash drive plugged into a UBS2 port (usually black plastic insert).  Not a USB3 port (Usually a blue plastic insert).

@Frank1940 , I tried all ports both USB2.0 & USB3.0.

You should be able to type this at the console:

Then tell me what error it spits out.

@limetech , I get this below:

12 hours ago, DeltaAlphaOscar said: @limetech , I get this below:   mount : /boot: special device / dev / disk / by - label / UNRAID does not exist .  

You are double-dog sure the USB flash device has volume label UNRAID ?  If so, I can't explain what the problem might be except some kind of issue with USB subsystem.

How about output of this command:

@limetech , 99.9% the volume is named "UNRAID"

I've used both manual method and the installer, and in all instances, the volume is labeled correctly when I looking in disk management. Hard to believe that the installer would incorrectly label it. I'll try that command when I get home. I'm also going to stop by Best Buy and get a few of the recommended drives to try out.

Doubt it will help in this case but might be worth a try creating flash with diskpart:

Backup config folder from flash, then in Windows open a command prompt window as administrator, then type in this order:

-select disk x (x=your flash drive)

-create partition primary

-format fs=fat32 label=UNRAID quick

-close cmd window

-unzip new Unraid install to flash

-restore the previously backed up config folder

-execute make_bootable as admin

Thanks to everyone that tried to help out. I tried many other flash drive to finally find one that works. 2 out of 11 flash drives worked. I could've stopped after the first one worked, but was curious so I tested all I had access to.  None of the Unraid recommended ones worked on my new build. All of them worked on my on my off-the-shelf Dell Inspiron.

What I've learned is that even if a drive boots on one computer, that it won't necessarily work in others.

If a mod wouldn't mind tagging this as resolved, that'd be great!

You should be able to do this yourself by editing your first post in this thread.

@Frank1940 , In these forums, is there anymore to it than just adding [SOLVED] to the title, or is there way to tag/flair it as solved.

Hey @DeltaAlphaOscar , Would you mind sharing which brands of USB worked for your system?? I'm having a very similar issue, and I if could increase my chances to more than 2 out of 11, that would be swell. I know that every system is different, and what works for yours might not work for mine.

  • 1 month later...

I eventually got to success by attempting starting with a totally new flash drive. By totally new, I mean I got flash drive, formatted it and then installed a demo version of the UnRaid. Much to my surprise, it worked immediately with the new hardware.  After a bit more exploration I discovered that my old flashdrive was running an older version of UnRaid. Once I updated it to a newer version, everything ran just fine. To any future readers, Please learn from my failure, just update the UnRaid OS.

How to manage network adapter settings on Windows 11

Here are the different ways to manage Wi-Fi and Ethernet network adapters on Windows 11.

Windows 11 manage network settings

Although Windows 11 can detect and configure network adapters automatically, you may still need to perform additional steps to connect to a wireless network, enable specific features, review configurations, and troubleshoot problems.

In previous versions, you needed to use Control Panel to manage various aspects of Wi-Fi and Ethernet adapters. However, on Windows 11, you can now configure most of the networking settings and features from the "Network & internet" section. For example, you can now enable or disable network adapters and configure DNS over HTTPS to improve security. It's a lot easier to set a static or dynamic IP address, configure data limits, reset the adapters to fix most problems, and more.

In this Windows 11 guide, you will learn the different ways to manage network adapter settings through the Settings app.

How to enable or disable network adapter on Windows 11

How to change network profiles on windows 11, how to make network connection metered on windows 11, how to manage known wireless networks on windows 11, how to connect to wireless network on windows 11, how to view wireless networks on windows 11, how to enable or disable wireless connection on windows 11, how to configure dns over https on windows 11, how to configure static ip address on windows 11, how to configure dynamic ip address on windows 11, how to configure network data limits on windows 11, how to reset network adapter on windows 11, how to view network data usage on windows 11, how to view network adapter properties on windows 11.

To enable or disable a network adapter, use these steps:

  • Open Settings .
  • Click on Network & internet .
  • Click the Advanced network settings page on the right side.
  • Under the "Network adapters" section, click the Disable button to turn off the network adapter.
  • Under the "Network adapters" section, click the Enable button to turn on the network adapter.

Once you complete the steps, the adapter will disable and no longer be available for the system. The adapter will again be available to provide networking functionalities if you enable the option.

On Windows 11, changing the network profile type allows you to increase the networking security and make it easier to share files and other services with another computer in the network.

Ethernet connection

To make a network connection public or private, use these steps:

  • Click the Ethernet page on the right side.
  • Public: Other computers in the network won't be able to see your device. This is the recommended option for the home, office, and public places.
  • Private: Other devices can see your computer in the network. When sharing files, printers, or using network applications, this option should be considered.

Wi-Fi connection

To change the network profile type for a Wi-Fi connection, use these steps:

  • Click the Wi-Fi page on the right side.
  • Click the connection properties setting. Quick note: The device must be already connected to the network to see the option.

After you complete the steps, depending on the profile you selected, the device will not be discoverable or be visible by other devices to access files and other services.

A metered connection reduces the background data usage of Windows 11 and apps to prevent going over a limited data plan, such as on mobile hotspot plans that only offer a few gigabytes of data.

To make an Ethernet connection metered on Windows 11, use these steps:

  • Turn on the Metered connection toggle switch.

To make a Wi-Fi connection metered, use these steps:

  • Click the connection properties setting.

Once you complete the steps, Windows and apps will use less data. For example, Windows 11 won't download cumulative or feature updates, and some features like OneDrive won't sync files to the cloud, and apps won't download updates.

The settings will only apply to the current connection. If you connect to a different network, you must reconfigure the feature as needed.

If you want to disable the feature, you can use the same steps, but on step 5 , turn off the Metered connection option.

On Windows 11, you can also provision Wi-Fi configurations to make connections easier. You can also delete those connections you no longer use for better management.

Add new Wi-Fi network

To provision a new wireless connection, use these steps:

  • Click the Manage known networks setting.
  • Click the Add network button.
  • Confirm the wireless network name.
  • Use the "Security type" setting and select the security authentication method. Quick note: This security feature is usually configured on the router or access point. Typically, it would be the WPA2-Personal AES option.
  • Use the Security key setting and confirm the security key (sometimes referred to as "Wi-Fi password").
  • (Optional) Check the Connect automatically option if you want to automatically connect to the wireless network when it is in range.
  • (Optional) Check the Connect even if this network is not broadcasting option. Quick note: Usually, you can choose the network to connect because it's broadcasting its presence to all devices. However, sometimes, administrators choose not to broadcast the network to remain hidden. This option will let you connect to the wireless network, whether it's broadcasting or not.
  • Click the Save button.

After you complete the steps, the network configuration will be applied to the device, and when the access point is within range, the computer will connect automatically without additional steps:

Remove existing Wi-Fi network

To delete a Wi-Fi connection from Windows 11, use these steps:

  • Click the Forget button for the network you want to remove.

Once you complete the steps, the network configuration will no longer be available on the device.

To connect a computer to a wireless access point, use these steps:

  • Click the Show available networks setting.
  • Select the Wi-Fi network.
  • (Optional) Check the Connect automatically option.
  • Click the Connect button.
  • Confirm the security key (Wi-Fi password).
  • Click the Next button.

Alternatively, you can also connect to the wireless network through the network icon in the Taskbar .

To view the Wi-Fi networks in range, use these steps:

After you complete the steps, you will see a list of the access points within range.

To disable or enable wireless connectivity on Windows 11, use these steps:

  • Turn off the Wi-Fi toggle switch.
  • (Optional) Use the Turn Wi-Fi back on setting and select the Manually option to keep the wireless off until you decide to turn it back on. Or use the times (1 or 4 hours or 1 day) to allow the system to reconnect automatically on schedule.

Once you complete the steps, the wireless radios will turn off and connections will not form, but the adapter will continue to be available in the adapter.

On Windows 11, DNS over HTTPS (DoH) is a network protocol to encrypt Domain Name System (DNS) queries using the standard Hypertext Transfer Protocol Secure (HTTPS) protocol to safeguard DNS queries, which results in improved security and privacy browsing the web.

Ethernet connection with DOH

To enable DoH on Windows 11, use these steps:

  • Click the Edit button for the "DNS server assignment" setting.
  • Select the Manual option.
  • Turn on the IPv4 toggle switch.
  • In the "Preferred DNS" setting, specify the IP address of the server that supports DOH.
  • Unencrypted only: DNS traffic is transmitted without encryption as normal.
  • Encrypted only (DNS over HTTPS): Windows 11 will only allow encrypted DNS queries.
  • Encrypted preferred, unencrypted allowed: The system will prefer DNS traffic encryption, but it will also allow queries without encryption.
  • (Optional) In the "Alternate DNS" setting, specify the IP address of the secondary address to use with DNS over HTTPS.
  • Use the "Alternate DNS encryption" setting and select one of the available options.
  • (Optional) Turn on the IPv6 toggle switch.
  • In the "Preferred DNS" setting, specify the IP version 6 address of the server offering DNS over HTTPS.
  • Unencrypted only .
  • Encrypted only (DNS over HTTPS) .
  • Encrypted preferred, unencrypted allowed .
  • (Optional) In the "Alternate DNS" setting, specify the IP version 6 address of the secondary address to use with DNS encryption.
  • Click the Save option.

After you complete the steps, the DNS queries will be sent encrypted over the internet.

Confirm DNS encryption

To confirm if the connection is encrypted, use these steps:

  • In the IPv4 DNS servers property, you should now see the new address and the Encrypted status.
  • In the IPv6 DNS servers property, you should now see the new address and the Encrypted status (if applicable).

Once you complete the steps, if you see the "Encrypted" status, DNS over HTTPS is working as expected.

Wi-Fi connection with DOH

To configure DOH for a wireless connection, use these steps:

  • Click the Hardware properties setting.

After you complete the steps, the wireless connection will transmit Domain Name System queries using the HTTPS protocol.

Once you complete the steps, if you see the "Encrypted" label, then it means DoH is working on Windows 11.

If you have a computer providing files, media content, and printers over the work, it should be using a static Transfer Control Protocol Internet Protocol (TCP/IP) configuration instead of a dynamic configuration.

The reason is that a dynamic network configuration assigned by the Dynamic Host Configuration Protocol (DHCP) server can always change. When they do, other devices in the network won't be able to access the network resources. On the other hand, a static IP configuration doesn't change, allowing the service to be always reachable.

Ethernet static settings

To set a static IP address configuration to an Ethernet adapter, use these steps:

  • Click the Edit button for the "IP assignment" setting.
  • In the "IP address" setting, specify the IP version 4 to assign the computer. Quick tip: The IP address should be within the network range, and it should be an address outside of the DHCP scope to avoid possible conflicts. For instance, if the network is in the 10.1.4.0 network and the DHCP assigns an address in the 10.1.4.10 through 10.1.4.100 range, a suitable static address could be 10.1.4.22 .
  • In the "Subnet mask" setting, specify the network mask — for example, 255.255.255.0 . Quick note: If you are configuring the settings on a home or office network, the subnet mask is typically 255.255.255.0 . However, it might be different if you are in a business environment.
  • In the "Gateway" setting, specify the gateway address (usually the router address) — for example, 10.1.4.1 .
  • In the "Preferred DNS" setting, specify the network DNS address (usually the router address in home and office networks) – for example, 10.1.2.1 .
  • In the "Preferred DNS encryption" setting, select the Unencrypted only option.
  • (Optional) In the "Alternate DNS" setting, specify a secondary DNS address that will be used in case the system can't find the correct route with the primary address.
  • In the "Alternate DNS encryption" setting, select the Unencrypted only option.

After you complete the steps, the computer will start using the new static network configuration.

Wi-Fi static settings

To configure a static TCP/IP configuration for a wireless adapter, use these steps:

  • In the "IP address" setting, specify the IP version 4 to assign the computer. For example, 10.1.4.23 .
  • In the "Subnet mask" setting, specify the network mask — for example, 255.255.255.0 .
  • In the "Preferred DNS" setting, specify the network DNS address (usually the router address in home and office networks) — for example, 10.1.4.1 .

Once you complete the steps, the wireless adapter will start using the new static IP address configuration.

We are focusing this guide on IP version 4, but you can also refer to these steps to set up an IP version 6 configuration if your network supports it. You only need to turn on the IPv6 option on step 7 and provide the IPv6 addresses according to your network configuration.

If you have a computer with a static IP address, you can also change its configuration to allow the device to receive the network settings through the local Dynamic Host Configuration Protocol (DHCP) server.

To change the IP address of an Ethernet adapter from static to dynamic, use these steps:

  • Select the Automatic (DHCP) option.

To set a dynamic IP address for a wireless adapter, use these steps:

After you complete the steps, the Ethernet or Wi-Fi adapter will configure its IP address automatically through its Dynamic Host Configuration Protocol (DHCP) server.

Windows 11 also comes with the ability to set data limits for a specific network adapter. As you get closer to the limit, the system will send you a warning to help you stay under your data limit.

To configure data limit on Windows 11, use these steps:

  • Under the "More settings" section, click the Data usage setting.
  • Click the Enter limit button.
  • Specify the monthly reset day or days until the data expires.
  • In the "Data limit" setting, specify the data allowance.
  • Confirm the data unit, including megabytes (MB) or gigabytes (GB).

Once you complete the steps, Windows 11 will notify you when the limit is getting closer to help you stay under the data limit.

When your laptop or desktop computer has connectivity issues, the reset feature will remove and install all the network adapters and reset all the configurations to their defaults to fix the most common problems.

To reset all the network adapter configurations, use these steps:

  • Click the Network reset setting.
  • Click the Reset now button.
  • Click the Yes button.

After you complete the steps, the feature will remove and reinstall all the network adapters and will reset all the network configurations to their defaults, hopefully fixing any Ethernet or Wi-Fi problems. If you also had a wireless connection, you may need to re-enter the authentication to connect to the network.

To view data usage per network adapter and apps on Windows 11, use these steps:

  • Review the device data usage.

Once you complete the steps, you will better understand the network data usage on your computer.

On Windows 11, you can find the network configuration information within the adapter's properties or through the Advanced network settings page.

Ethernet properties

To find out the IP address and other network settings of the Ethernet adapter, use these steps:

  • Confirm the networking settings at the bottom of the page.

Wi-Fi properties

To determine the properties of the wireless adapter, use these steps:

Ethernet and Wi-Fi properties

To view the network information for the adapters installed on Windows 11, use steps:

  • Click the Hardware and connection properties setting.

After you complete the steps, you will be able to determine many networking configurations, such as link speed, IPv4 and IPv6 addresses, DNS server, driver version and manufacturer, MAC address, and more.

Unable to Assign Static IP Address option greyed out

Quick one that came up today.  Looking on the web for the search term above only found mention that the RRAS server may not have been set to use a static pool of addresses and that is why, in AD Users and computers on the dial in tab, this was grayed out as an option.

The thing was, I was using a static pool.

The answer is, in my case, that this was a Windows 2000 Small Business Server that was still running in Mixed mode.   Changing the domain to Native mode allowed me to enter the static IP for a RRAS Dial in client.

The second part of the problem was more confusing.   On adding an IP to the accounts dial in properties, and clicking apply, I get the error “member profile changes were not saved because member not found” message.   Very odd…   Ahh, a reboot fixed that….

Issue with using windows server 2012 rras as a local vpn device with microsoft azure when wan interface has dhcp assigned ip address.

In my personal lab I use a Windows Server 2012 R2 VM running on a local Hyper-V server as my VPN device to connect to a Microsoft Azure Virtual Network gateway. This setup has been working fine for quite some time, and is indeed a supported configuration. Recently though I could not make it connect. Come hear the story…

My ISP (Telenor) here in Norway is gracious enough to provide me with 2 dynamically assigned official IPv4 addresses. I use one for my home network and the other for the Azure gateway. I hadn’t used the lab for some time so the S2S VPN had been down. When I tried to reconnect it wouldn’t work.I knew Microsoft had made some changes recently, these were announced during Build 2014, so I figured I would reset the RRAS configuration and run the VPN setup from scratch. So I disabled the RRAS service and downloaded a fresh VpnDeviceScript.cfg file from the portal an redid everything. This didn’t take more than a couple of minutes, but still I could not connect. I noticed that when the RRAS service started I lost all connectivity on my WAN (Internet) interface. I could ping an address on the Interne, but the ping immediately stopped when RRAS started. I fired up Wireshark and did a trace of the WAN interface during RRAS startup and discovered that when the service starts several DHCP Discover messages were sent out on the WAN interface:

Since my ISP only allows 2 IPs this made the original address I had received on the WAN interface invalid. But why did it happen?

Also during RRAS startup I got this warning in the System log:

When RRAS is running as a remote access service, which it does when providing Site-2-Site VPN tunneling, it also supports incoming VPN requests from clients. These clients need an IP address to be able to communicate on the local network. They get this address either from the RRAS server itself and a static IP pool, or from a DHCP server on the local network where the RRAS reserves IP addresses in blocks of 10. In my case I had DHCP selected and thus no static IP pool configured. If the RRAS server is multi-homed, which it usually is, you can select which interface RRAS looks for a local DHCP server on.This settings is configured through the RRAS server properties:

The default setting is Allow RAS to select adapter . This was the cause of my problem. The RRAS service selected my WAN interface and send out a bunch of DHCP Discover messages to allocated IP addresses for incoming clients. This invalidated my existing DHCP lease and stopped all communication on the Internet. Once I selected the internal (LAN) Interface I could connect fine.

I guess this problem can occur in any S2S or RAS scenario where the WAN IP address is dynamically assigned.

VPN with static IP

I am trying to setup our Windows 2003 RRAS server to assign a static IP address to specific users however that option under Dial-In in AD is greyed out.  I currently have a static pool of addresses set up and the VPN is functioning.  I did try to set a static IP in the client's VPN settings and I kept getting error 720 and the event logs show error 20050 (no network protocols were successfully negotiated).  I tried it with an IP in the static range, DHCP range, and reserved range and all of them had the same result.  Any ideas on why the option is greyed out?  I am connecting from a Win 7 machine.

Configuring VLANs on AOS-S Switches

AOS-S switches support the following types of VLANs Virtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. :

  • Port-based VLANs—In the case of trusted interfaces, all untagged traffic is assigned a VLAN based on the incoming port.
  • Tag-based VLANs—In the case of trusted interfaces, all tagged traffic is assigned a VLAN based on the incoming tag.

Adding VLAN Details

By default, all ports in the Switches are assigned to VLAN 1. However, if the ports are assigned to different VLANs, the VLANs page displays their details.

To add a VLAN, complete the following steps:

The dashboard context for the group is displayed.

  • Under Manage , click Devices > Switches .
  • Click the AOS-S or Config icon to view the switch configuration dashboard.
  • Set the filter to Global or a group containing at least one switch.

A list of switches is displayed in the List view.

The dashboard context for the switch is displayed.

The tabs to configure the switch is displayed.

  • Click Interface > VLANs . The VLANs page is displayed.
  • In the Ports table, select the port number(s).
  • Tagged Ports
  • Untagged Ports
  • To assign the VLAN to a trunk group, select the trunk group in the Trunk Groups table.
  • Click Save Settings .

When you upgrade to Aruba Central version 2.5.2, the static IP address configured at group level for VLANs is migrated to device level and preserved as overrides. The static IP assignment is available only at the device level.

Editing the VLAN Details

To edit the details of a VLAN, point to the row for the VLAN, and click the edit icon in the Actions column, and configure the parameters.

Deleting VLAN Details

To delete the VLAN details, complete the following steps:

  • Ensure that the VLANs are not tagged to any ports.
  • Point to the row for the VLAN, and click the edit icon in the Actions column.

VLAN 1 is the primary VLAN and cannot be deleted.

Configuring DHCP Relay Settings

You can configure a switch as a DHCP relay agent for transmitting DHCP messages between the DHCP server and client. You can also configure the option-82 feature for the switch to include DHCP relay information in the forwarded DHCP request messages.

To configure a switch as a DHCP relay agent, complete the following steps:

  • Click the Config icon to view the switch configuration dashboard.
  • Expand the DHCP Relay Settings accordion.

DHCP Relay option is enabled by default.

  • To enable option-82 feature, move the DHCP Relay Option 82 toggle switch to the on position.

You are here, explained: how is my ip assigned / determined (ipv4).

Dennis Faas's picture

Infopackets Reader Izzy M. writes:

" Dear Dennis,

I am trying to figure out how IP addresses are assigned using IPv4 (IP addressing version 4), but can't seem to find a straight answer online. My question: is there a certain number that my IP address has to be? Is there any correlation between my IP address, subnet mask and default gateway? How is my IP address assigned or determined? Thank you in advance! "

My response:

I think the reason you can't find an answer to this question is because this is an extremely broad question. To put this as simple as possible: the answer to your question depends on your network class (A, B, C, D). The network class then determines whether you are referring to a public IP address which is assigned to your modem by your Internet provider, or a private IP address which is typically assigned by your router on a home network.

Related: How Do I Change my IP Address (IP Banned) ?

Your IP address (with respect to IPv4) is derived from three main things:

1. Your network class (A, B, C, D) - this defines whether you're using a public IP address (from your Internet provider) or a private IP address (typically assigned by your router, on your home network). For the record you can review a list of public IPs (IPv4) here .

2. The subnet , which defines how many IPs are assigned to the network class range

3. Whether the IP is leased or permanent ( static or dynamic )

How an IP is Assigned on a Home Network (IPv4)

Let's look at a typical example for a home user.

Internet access is provided by an Internet Service Provider (ISP) ; data travels from the Internet to a modem inside your home (usually). A router connects to the modem and allows your home network to communicate to the outside world (to the Internet).

The router usually has DHCP (dynamic host control protocol) enabled by default. The purpose of DHCP is to automatically assign any device on your network an IPv4 address. This allows you to share the Internet across multiple devices in your home (or office), and even communicate with other devices across your entire private network.

Here's where things get a bit more technical.

The subnet mask is used to define a subnet range on the network. As a typical example, most routers are assigned a class C range. Class C is defined as having IPs 192.168.0.0 to 192.168.255.255 , which yields a total of 2,097,150 usable IP addresses . This is far too large for most home networks; as such, a subnet mask is applied to yield a smaller range of usable IPs on the network.

Thus, a typical network class C range (for use at home) would be 192.168.0.1 to 192.168.2.254 with a subnet mask of 255.255.255.0 , yielding 254 usable IP addresses. There is a mathematical way to derive how IPs are subnetted , which I will not get into - but you read read up on, if you want.

Of that IP range, certain IPs are reserved for special cases. For example:

  • 192.168.0.1 is usually the default gateway (also used for the router administration page)
  • 192.168.0.2 - 192.168.0.100 are usually reserved for dynamic addresses , controlled by DHCP ; these IPs are leased and expire over time, thus DHCP IPs are not always the same
  • 129.168.0.101 - 192.168.0.254 are usually reserved for static IPs
  • 192.168.0.255 is the broadcast IP

Assigning an IPv4 Address: Using DHCP or Static IPs

On a typical home network, an IPv4 address is assigned depending on how the router and your machine are configured.

By default, DHCP (dynamic host control protocol) is enabled on the router. This means that the router will automatically assign an IP address to any device on the network automatically according to the DHCP IP range . The DHCP range is defined in the router administration page. Using the example above, the range would be 192.168.0.2 to 192.168.0.100.

If you prefer to set a static IP rather than one through DHCP, this would be done by adjusting your network adapter settings in the operating system. For example, if you have a ' server ' or ' media pc ' machine in the home and you want to use the same IP address for that device all the time (instead of a random IP address), then a static IP address makes more sense.

I hope this answers your question.

Keep in mind that this is an extremely broad question with many variables involved. That said, in the case of 'home networking' this answer should fit. In the case of how an IP is assigned using an Internet Provider : the same ideas apply, except DHCP is controlled by the Internet Provider and IPs are leased for a certain duration of time (especially if your modem or router loses power).

DHCP (dynamic host control

DHCP (dynamic host control protocol)

I know you will get some more comments on this so I am giving you a heads up. DHCP is most commonly referred to as Dynamic Host Configuration Protocol (DHCP). It appears that it can be called Dynamic Host Control Protocol as referenced on the below noted Cisco page but its technical name is Dynamic Host Configuration Protocol. The header in the Cisco page uses the word control but the rest of the page references it as configuration. It may be a country related variation that I am not aware of and if so ignore my post please.

(https://www.cisco.com/c/en/us/products/ios-nx-os-software/dynamic-host-control-protocol-dhcp-domain-name-system-dns/index.html)

Used interchangeably

Dynamic Host Control Protocol and Dynamic Host Configuration Protocol are used interchangeably but refer to the exact same thing. Thanks for pointing it out. Old school users like myself refer to it as Dynamic Host Control Protocol.

IP assignment

It would be good to point out that every IPv4 address has 4 numerical values separated by a period. Each of these values range between 0-255. Every ISP has a range of public IPs they assign to their customers. These IPs are given to your home gateway or router. This allows your router to communicate with your ISP's system. All residential/consumer accounts have a dynamic IP assignment, which means that the IP changes every so often. The normal standard is 7 days, and does not always change when the router reboots. However this is normally something you would not see within your home network.

Like Dennis said, most home routers will have a config/gateway IP address of 192.168.x.x. Those x's are either 0's or 1's, depending on what the manufacturer sets. With router DHCP configurations, some default to start IP assignments in the 192.168.x.100 range. If you decide that you want to set static IP assignments for your devices within your home network, note that they all have to match the first 3 fields in the IP address and cannot be the same as the gateway IP. (Unless you change your subnet mask, which then complicates things.) So if your router is configured with a gateway IP of 192.168.1.0, then your devices can have any IP address that falls within the range of 192.168.1.(1-255).

DHCP normally assigns IP addresses in sequential order starting with the first device it connects with. So if the gateway is 192.168.1.0 and it's set to start from the 100 range, the first device will be assigned 192.168.1.100, the next will be 192.168.1.101, and so forth.

For your public IP assigned to you by your ISP they have bigger routers that essentially do the same thing, for your neighborhood, only they can be confogured with a wider range of IP addresses.

I hope this digs a bit deeper, but doesn't get confusing for those who are wanting to learn a bit more. The IP classes & subnet masks are more for high-level corporate networks where they need to separate networks or merge location networks for purposes of maintaining an intranet or VPN connection, which then goes beyond the scope of my own knowledge.

Create, change, or delete an Azure public IP address

  • 13 contributors

On September 30, 2025, Basic SKU public IPs will be retired. For more information, see the official announcement . If you are currently using Basic SKU public IPs, make sure to upgrade to Standard SKU public IPs prior to the retirement date. For guidance on upgrading, visit Upgrading a basic public IP address to Standard SKU - Guidance .

Learn about a public IP address and how to create, change, and delete one. A public IP address is a resource with configurable settings.

When you assign a public IP address to an Azure resource, you enable the following operations:

Inbound communication from the Internet to the resource, such as Azure Virtual Machines (VM), Azure Application Gateways, Azure Load Balancers, Azure VPN Gateways, and others.

Outbound connectivity to the Internet using a predictable IP address.

Azure provides a default outbound access IP for VMs that either aren't assigned a public IP address or are in the back-end pool of an internal basic Azure load balancer. The default outbound access IP mechanism provides an outbound IP address that isn't configurable.

The default outbound access IP is disabled when one of the following events happens:

  • A public IP address is assigned to the VM.
  • The VM is placed in the back-end pool of a standard load balancer, with or without outbound rules.
  • An Azure Virtual Network NAT gateway resource is assigned to the subnet of the VM.

VMs that you create by using virtual machine scale sets in flexible orchestration mode don't have default outbound access.

For more information about outbound connections in Azure, see Default outbound access in Azure and Use Source Network Address Translation (SNAT) for outbound connections .

Create a public IP address

For instructions on how to create public IP addresses using the Azure portal, PowerShell, CLI, or Resource Manager templates, refer to the following pages:

Create a public IP address - Azure portal

Create a public IP address - PowerShell

Create a public IP address - Azure CLI

Create a public IP address - Template

The portal provides the option to create an IPv4 and IPv6 address concurrently during resource deployment. The PowerShell and Azure CLI commands create one resource, either IPv4 or IPv6. If you want an IPv4 and a IPv6 address, execute the PowerShell or CLI command twice. Specify different names and IP versions for the public IP address resources.

For more detail on the specific attributes of a public IP address during creation, see the following table:

View, modify settings for, or delete a public IP address

View/List : Review settings for a public IP, including the SKU, address, and any association. Associations can be load balancer front-ends, virtual machines, and other Azure resources.

Modify : Modify settings using the information in create a public IP address . Settings such as the idle timeout, DNS name label, or assignment method. For the full process of upgrading a public IP SKU from basic to standard, see Upgrade Azure public IP addresses .

Remove the address from any applicable IP configurations (see Delete section) to change assignment for a public IP from static to dynamic. When you change the assignment method from static to dynamic, you lose the IP address that was assigned to the public IP resource. While the Azure public DNS servers maintain a mapping between static or dynamic addresses and any DNS name label (if you defined one), a dynamic IP address can change when the virtual machine is started after being in the stopped (deallocated) state. To prevent the address from changing, assign a static IP address.

  • Delete : Deletion of public IPs requires that the public IP object isn't associated to any IP configuration or virtual machine network interface. For more information, see the following table.

Virtual Machine Scale Sets

There aren't separate public IP objects associated with the individual virtual machine instances for a Virtual Machine Scale Set with public IPs. A public IP prefix object can be used to generate the instance IPs .

To list the Public IPs on a Virtual Machine Scale Set, you can use PowerShell ( Get-AzPublicIpAddress -VirtualMachineScaleSetName ) or CLI ( az Virtual Machine Scale Set list-instance-public-ips ).

IPv6 home set-up | OpenWrt 18.06.1 - how to?

I am struggling with the IPv6 home set-up. I don't understand networking much to be honest.

My ISP informed me last year he is IPv6 fully capable.

I did not manage to set it up in my router since then. I told them, but they don't care much since almost all web is Dual-stack / IPv4 capable.

So, they only came once to check if the problem is on their side: they claim it is not and that either my operating systems (Windows 10 Pro, Linux Mint 19.0 Cinnamon, Android 7.0) and their settings are the problems, or the router is badly set-up.

The problem

Since I am sure to have the IPv6 enabled in all of the mentioned systems, I come to realize that maybe my router is old , please understand it as no more supported, the model is: TP-Link Archer C5 v1.2 with firmware dated 2015-04-28 .

Somehow sometimes, even early today I was able to get a set-up from DHCPv6 as follows:

The question (original)

Is such setting as above even technically correct, I mean I see the gateway as probably local-only address, is that the problem due to which I cannot browse IPv6-only sites?

UPDATE - OpenWrt

I am entirely new to OpenWrt. Please guide me. Thank you.

I have managed to upload OpenWrt 18.06.1 into my router and also made both the Wifi 5G and 2.4G working, with a public static IPv4 address.

Basic information

  • Model: TP-Link Archer C5 v1
  • Architecture: Qualcomm Atheros QCA9558 ver 1 rev 0
  • Firmware Version: OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152)
  • Kernel Version: 4.9.120

I am able to SSH to the router as root . Here are the most basic information.

To answer the comment:

can you ping ipv6.google.com ? the ip addresses look logical. Its also worth mentioning what your ISP settings are - I had to find mine on their forums back in the day and the settings varied based on whether you're on cable or fibre. Some local knowledge might be useful here.

Not able to ping6 . 100% packet loss.

ISP settings - see below.

I am on normal cable = ethernet = about 20/10 Mbit/s.

Ask me anything.

Current statuss from GUI:

Current statuss from GUI

I have tried to use DHCPv6 without success. That is why I posted this question.

Name: Starnet s.r.o.

Web: http://www.starnet.cz/

ASN: 44489, see here

IPv6 assignment: They told me they use the Native IPv6 using DHCPv6.

I have been informed by the ISP, they assign prefixes automatically through DHCPv6, and that no static configuration is possible at this point.

So, I removed all of the static settings and turned on DHCPv6 with a forced request for a 64 prefix.

Before I hit apply for enabling the DHCPv6 in WAN6 section, it looked like:

This did not change a thing, what's more, the IPv6 uplink is greyed out as Not configured.

In light of the fact they want an enormous amount of money without any guarantee that their technician would solve the problem in my place, I'm hereby putting one juicy bounty on this question.

I will try to edit this question in order for it to be clearer anytime you ask me a new question.

I browse the OpenWrt interface each day for 3 days, but maybe just maybe I found something new (to me at least), it is called VLANs, and I don't know what is its purpose, so I am posting it:

VLAN settings

ISP StarNet

I have found they do have some not really valuable information on their website:

http://www.starnet.cz/info/ipv6

Which you can easily Google translate for instance.

Another thing confirmed, I have found on their Facebook page :

The prefix is 64. And they plan on making 56 also.

At the current setting, and directly from LuCI (GUI) interface, when I try to ping6 ipv6.google.com , I get:

I have found the following bug report of my exact version:

https://bugs.openwrt.org/index.php?do=details&task_id=1763

The person suggests downgrading to 17.0.1.5 solves the IPv6 issue, could anyone competent have a look at that bug report for me, I don't really understand it.

Bug confirmed

The bug report is absolutely correct, I do not understand why it is not assigned or why it has very low priority, but I was able to get IPv6 address prefix on 17.x firmware:

IPv6 is on in 17.x firmware

I don't have internet connection from the 17.x firmware, just able to ping and ping6 directly from the router, please help me out to figure this out.

IPv6 Upstream is finally on!

IPv6 Upstream is finally on

After downgrade to 17.x, there was no internet connection available from the clients, but when upgraded back to the 18.x firmware, IPv6 Upstream is finally on.

The last step should be enabling IPv6 to the clients. I have no IPv6 on Windows / Linux / Android, so there is something wrong, I just don't know what it is.

Bounty is still On

I respect rules, so there will be no cancel bounty requests anymore.

In order to grant someone those 300 points offered, I have some bonus questions for you.

Bonus questions for 300 points

Could anyone explain to me the difference and usefulness of the Stateful and Stateless IPv6 assignment? Maybe security implications including. Heavily cited please, thank you.

Could you further explain what DUID = DHCP Unique IDentifier is for? I mean what is its purpose and usage. Maybe security implications including. Heavily cited please, thank you.

In a nutshell:

Stateful DHCPv6 auto-configuration of IPv6 is the equivalent of DHCP in IPv4. A DHCPv6 service provides the IPv6 address to the client device and both client and server maintain the "state" of that address (i.e. lease time, etc). The router in its router advertisement message will tell the newly come-up host to ask for all address (global address, DNS address, SIP proxy server address) from the DHCPv6 server.

Stateless DHCPv6 is for the auto-configuration by the client device of its IPv6 address and routing based on the router advertisements. The router tells the newly come-up host to take only the extra information like DNS, SIP proxy server address from the DHCPv6 server, while the global address is given to the host by the prefix present in the router advertisement message. The router gives the prefix of 64 bits and the host uses its MAC address (48 bits) converted in EUI-64 method to obtain a global IPv6 address.

In detail, from the article What is the difference between stateful and stateless IPv6?

IPv6 address assignment options Static (manual) address assignment – exactly like with IPv4. Stateless Address Auto Configuration (SLAAC) – nodes listen for ICMPv6 Router Advertisements (RA) messages periodically sent out by routers on the local link, or requested by the node using an RA solicitation message. They can then create a Global unicast IPv6 address by combining its interface EUI-64 (based on the MAC address on Ethernet interfaces) plus the Link Prefix obtained via the Router Advertisement. This is a unique feature only to IPv6 which provides simple “plug & play” networking. By default, SLAAC does not provide anything to the client outside of an IPv6 address and a default gateway. SLAAC is greatly discussed in RFC 4862. Stateless DHCPv6 – with this option SLAAC is still used to get the IP address, but DHCP is used to obtain “other” configuration options, usually things like DNS, NTP, etc. The advantage here is that the DHCP server is not required to store any dynamic state information about any individual clients. In case of large networks which has huge number of end points attached to it, implementing stateless DHCPv6 will highly reduce the number of DHCPv6 messages that are needed for address state refreshment. Stateful DHCPv6 – functions exactly the same as IPv4 DHCP in which hosts receive both their IPv6 address and additional parameters from the DHCP server. Like DHCP for IPv4, the components of a DHCPv6 infrastructure consist of DHCPv6 clients that request configuration, DHCPv6 servers that provide configuration, and DHCPv6 relay agents that convey messages between clients and servers when clients are on subnets that do not have a DHCPv6 server. You can learn more about DHCP for IPv6 in RFC 3315. NOTE: The only way to get a default gateway in IPv6 is via a RA message. DHCPv6 does not carry default route information at this time.

DHCP Unique Identifier

This is a unique identifier generated by the client itself that serves to uniquely identify it for the DHCPv6 server.

From Wikipedia DHCPv6 :

DHCP Unique Identifier The DHCP Unique Identifier (DUID) is used by a client to get an IP address from a DHCPv6 server. It has a 2-byte DUID type field, and a variable-length identifier field up to 128 bytes. Its actual length depends on its type. The server compares the DUID with its database and delivers configuration data (address, lease times, DNS servers, etc.) to the client. The first 16 bits of a DUID contain the DUID type, of which there are four types. The meaning of the remaining DUID depends on the type.

So, there were two separate problems:

WAN - IPv6 Upstream not connecting

LAN - Error in the configuration

For #1, i.e. WAN configuration, I tried pretty much everything that the GUI offers without success.

Since I finally came with a workaround, I will share it with you:

Downgrade to the 17.x firmware. It will keep your settings, don't worry.

Upgrade back to the 18.x firmware.

That's all, magically the IPv6 WAN Upstream is finally connecting.

For #2, i.e. LAN configuration, set it up as follows:

Network - Interfaces - LAN - Common Configuration - General Setup tab - IPv6 assignment length must be set to the length of your prefix.

Network - Interfaces - LAN - DHCP Server is based on how you topology is like, in my case the following works:

Router Advertisement-Service: server-mode

DHCPv6-Service: server-mode

NDP-Proxy: hybrid-mode

DHCPv6-Mode: stateless + stateful

I will keep this answer updated if I find further errors in the configuration.

I have now tested my Windows 10, Linux Mint 19, and Android 7.0 on http://test-ipv6.com/

Test with IPv4 DNS record

Test with IPv6 DNS record

Test with Dual Stack DNS record

Test for Dual Stack DNS and large packet

Test IPv4 without DNS

Test IPv6 without DNS

Test IPv6 large packet

Test if your ISP's DNS server uses IPv6

Find IPv4 Service Provider

Find IPv6 Service Provider

which is 100% Ok. Those 2 skipped tests were caused by accessing the test site using HTTPS, which is still in beta there, so it is probably better to use plain HTTP: http://test-ipv6.com/

That's it. I now need to fiddle around firewalls and stateful + stateless IPv6, but that will not change the fact, that I've managed to make IPv6 work in my home.

I found one additional test site, which could be useful:

IPv6-only: http://v6.testmyipv6.com/

Dual-Stack: http://ds.testmyipv6.com/
