How to Add a Static IP to an AWS EC2 Instance

Introduction.

AWS Elastic Compute Cloud (EC2) is a popular option for cloud computing services. It offers virtual servers (or instances) as well as security, networking, and storage options. EC2 can launch as many or as few virtual servers as you need, depending on your projects.

Using EC2 offers multiple benefits, including the ability to run your applications in the cloud and to create virtual machines (VMs) with whatever configurations you might need. The infrastructure is scalable, with over 500 instances, and EC2 supports developing macOS and machine learning applications.

EC2 works with static (aka elastic) IP addresses. Whenever a resource on a network is assigned an IP address, that IP address is either dynamic—meaning it’s assigned by the network it’s connected to and changes periodically—or static, meaning it never changes. An elastic IP address in EC2 is public, so it’s reachable from the internet. Because it’s set to your AWS account, an elastic IP address can be remapped to another instance as needed in case of bugs or other issues. A custom IP address can also be added to your account rather than use one from AWS.

Elastic IP addresses are provided via a Dynamic Host Configuration Protocol (DHCP). These IP addresses are persistent, meaning they will not change when the VM is restarted or shut down.

In this tutorial, I'll walk you through how to configure an elastic IP address with an AWS EC2 instance.

Prerequisites

This article doesn't have many prerequisites, it is a tutorial which will assume you already have an AWS EC2 instance provisioned already, that is ready to be associated with an elastic IP address. In case you do not already have an AWS EC2 instance running, please create one before proceeding with the rest of this guide.

Let's dive right in!

Step 1: Choosing Elastic IP

From the AWS console, navigate to EC2 by clicking Compute . This should take you straight to your EC2 dashboard.

Navigate to dashboard

On your dashboard, click on Elastic IPs under Network & Security .

Elastic IPs

Step 2: Creating New IP

Click on Allocate Elastic IP address to create a new static IP address.

Allocate IP

Proceed by clicking Allocate .

IP options

Step 3: Assigning IP to EC2 Instance

Once the allocation request is successful, assign the static IP to your EC2 instance.

On the elastic IP view, select the IP you just allocated and click the Actions dropdown.

Actions menu

Select the View details button to reveal the info page on the elastic IP.

Elastic IP details

On this page, click the Associate Elastic IP address button.

Associate IP address

Step 4: Associating IP to Instance

Search for your instance ID from the Instance field.

Locate instance ID

Select the instance ID and scroll down to click the Associate button.

Associate IP

Step 5: Checking The Instance View

Your elastic IP address has now been associated with your EC2 instance. Head to your instance view by clicking on your instance ID. The address of your static IP is now displayed on the view.

IP associated successfully

Step 6: Connecting to The Instance

Connect to your EC2 instance with the newly associated static IP. On your instance view, click Connect . A view with connection details can now be seen. If you’re using a Linux or Mac system, open up your terminal.

Instance summary

Select SSH on the connect view. This tutorial connects via SSH through PowerShell.

Connect to instance

Set permissions on private key if you haven’t already by pasting one of the below commands in your terminal or CLI:

Option A: Linux

Set permissions on Linux for private key

Option B: Windows (PowerShell)

Set permissions on Windows for private key

You can copy-paste the second command shown on your instance description to connect to your remote instance:

Connect to EC2 instance

Enter Yes to proceed.

CLI connected to instance

The instance is now connected, as shown below, this was validated by confirming the present working directory with the command pwd . Please proceed with building whatever solution you want to deploy on your EC2 instance.

Connected EC2 instance

Limits on Elastic IPs

According to this AWS documentation on service quotas, “Your AWS account has default quotas, formerly referred to as limits, for each AWS service.” The important thing to understand is that static IPs on EC2 instances have a limit of five IPs per region per account, so you can’t allocate more than five static IPs in the same AWS region. If you already have up to five elastic IPs, you can either delete one or select a new AWS region before allocating a new IP.

If you need to confirm your elastic IP address limit, head over to your EC2 dashboard. Select Limits from the left pane and type in IP in the search box. You should immediately see the EC2-VPC Elastic IPs limit. Click on it for more details about the limit quota.

Remember, the good thing about elastic IPs is they don’t change or expire, unless they are disassociated from an instance and released.

Request an increase to your quota from the Service Quotas Console if the need arises.

In this tutorial, you learned how to set up an elastic IP address and connect it remotely with your AWS EC2 instance. As you saw, this is a simple process that gives you more control over your EC2 instance and allows you to choose your own IP address for as long as you need it.

Assign a static private ip to an EC2 instance

I want my server to connect to a db server (both on an EC2 instance). How can i give the db server a static IP address to use within EC2 without using VPC?

  • 1 Just use a VPC. Hell, it's the default for new accounts. Takes an extra five minutes to set one up and comes with all sorts of benefits. –  ceejayoz May 1, 2014 at 15:35

Elastic IPs are the only way without using a VPC. You can use a Security Policy to restrict all public traffic so you'd essentially have a private IP address (plus, these are free).

Edit: As pointed out by @ceejayoz, this incurs Internet bandwidth fees and is not the recommended method. Unless you absolutely cannot use VPC for some reason, use it. Otherwise, use the "internal" EC2 assigned IP or static as a last resort.

Nathan C's user avatar

  • 1 Elastic IP is a fixed public IP. I don't think it gives you a fixed private one. DB traffic over a public IP will suck. –  ceejayoz May 1, 2014 at 15:35
  • @ceejayoz Traffic is still routed like it was private. I had two instances once with static IPs, and they were one hop from each other provided they were in the same zone. –  Nathan C May 1, 2014 at 15:37
  • @ceejayoz But I agree with your statement...VPC is the de-facto way. –  Nathan C May 1, 2014 at 15:38
  • Nathan, per the EC2 docs, "Instances that access other instances through their public NAT IP address are charged for regional or Internet data transfer, depending on whether the instances are in the same region." Definitely not the same on a billing basis, and that's likely because they're not the same on a technical basis too. –  ceejayoz May 1, 2014 at 15:45
  • 4 Referencing the elastic ip by its dns name will resolve to the internal ip where possible avoiding data transfer charges. –  Matt Houser May 1, 2014 at 22:48

How to Assign Elastic IP address to your EC2 Instance in AWS

How to Assign Elastic IP address to your EC2 Instance in AWS

Dear Reader, hope you are doing great today. In this blog post you are going to learn about elastic IP and how you can assign an elastic IP to your EC2 Instance.

One of the biggest benefits of compute capacity in cloud such as EC2 is to be able to start, stop, hibernate or terminate your instance within a matter of seconds.

However, there is a downside as well. If you stop your EC2 instance and start it again, the IP address of your instance changes. That means your instance is no longer accessible using your old IP address.

We will learn how we can solve this problem using Elastic IP addresses.

By the end of this tutorial you should be able to know-

  • What is Elastic IP?

What Problem Does it solve?

  • How to Release an Elastic IP address from EC2 Instance

So let’s get started.

What is an Elastic IP?

An Elastic IP is a pubic IP address that you can allocate to your AWS account. Once allocated, you can associate this elastic IP to any of your EC2 instance, disassociate from one instance and re-associate to another.

That means it’s a reserved public IP address that you can assign to your EC2 instance. We will learn it’s significance in next section.

Let’s know a bit about public IP address.

What is a public IP?

A Public IP address is an IP address that can be accessed directly from internet. If your EC2 instance has public IP that means your instance is reachable over internet or it can communicate with internet.

Whenever you are trying to access your EC2 instance outside of your VPC, you need to use your instance’s public IP. As private IP’s are only accessible from the VPC.

That means an elastic IP is nothing but a static public IP using which you can always connect/access your instance even if it stops and starts or you fail over to a different instance.

When you launch your EC2 instance in a default VPC, your instance receives a public IP at launch. You can use that to connect to your instance.

But the problem is, every time you stop your EC2 instance and start it again, public IP of your instance changes.

Now imagine if you are hosting your application on EC2 and the public IP changes. What is gonna happen?

Well, it’s simple !!!!

Your application becomes inaccessible.

You might think that you will use the new IP address instead. Well that will work of course. But what if you are using a custom domain name where you have specified the IP address of the instance. It is almost impossible and impractical to update the A record manually each time IP address changes.

What’s the solution then?

Well one of the simplest solution is to attach an Elastic IP to your instance. Now even if your system stops , starts or hibernate, your instance has elastic IP attached to it. Even if your instance got terminated somehow, you can launch a new instance and attach the same elastic IP to new instance. By doing this, at route 53 level you wont have to touch and no body will know that behind the scene you failed over from one instance to another.

Now that’s good.

Note: Please know that this is one possible solution however it is recommended to use a load balancer which provides singe entry point to your application using a DNS.

Prerequisite: Launch an EC2 Instance in AWS Step by step

Allocate an Elastic IP

Assign the allocated ip to your instance.

  • Login to  AWS Management Console  and open EC2 service

You can either go to Services -> Compute -> EC2

or type EC2 in the search bar and hit enter. Once you see EC2 option click on that.

How to Assign Elastic IP address to your EC2 Instance in AWS

This will lead you to EC2 dashboard.

2. Scroll down the left navigational menu and Click Elastic IPs from Network and Security Section

assign static ip ec2

3. Click on Allocate Elastic IP address as shown in above screenshot

Keep everything default if you want to use an IP from amazons pool and click Allocate

assign static ip ec2

Once you click Allocate , your static public IP or Elastic IP is allocated successfully and you see similar success response like below

How to Assign Elastic IP address to your EC2 Instance in AWS

By this time we have allocated an Elastic IP in our account and we also have an EC2 instance running. So lets associate the Elastic IP to our instance.

Select the newly created Elastic IP, Click Actions and choose Associate Elastic IP address

assign static ip ec2

Select Resource Type as Instance and choose your instance from the instance field(All your running instances will be shown here)

assign static ip ec2

After You have chosen your instance, click Associate

And there you go !!!

The Elastic IP is now associated with your instance and you get to see success message like below

How to Assign Elastic IP address to your EC2 Instance in AWS

To verify that, stop and start your instance and this time you will notice that Public IP will remain same across stops and starts.

You will also see that Elastic IP is your public IP now. As you can see in the below screenshot, public IP and elastic IP field has got same value 🙂

How to Assign Elastic IP address to your EC2 Instance in AWS

Release the Elastic IP from your Account

Make sure to release the Elastic IP when you don’t need it so that you don’t get billed for it.

If the Elastic IP is still in use, you need to disassociate the IP from instance in order to release it. However, if you have already terminated your instance and Elastic IP is unused you can release the Elastic IP straightway.

Select your Elastic IP, choose Action and then Release Elastic IP addresses

assign static ip ec2

On review popup screen, click Release and your Elastic IP is successfully released.

How to Assign an Elastic IP address to your EC2 Instance in AWS

How To Assign An Elastic Ip Address To Your Ec2 Instance In Aws

How to Assign an Elastic IP address to your EC2 Instance in AWS. In this guide you are going to learn the importance and necessary of Elastic IP address and how to assign it to your EC2 Instance.

The Elastic IP should be assigned to an instance, if it is not assigned you may incurr additional billing for idle time usage. So if you have any unassigned Elastic IP address, make sure to remove them.

Once you create a new EC2 Instance your instance will get a new public IP address. But this IP address is not static so it will change or a new IP will get assigned to your instance when certain actions are made on your instance like restarting your instance.

If you have your public IP address configured in your DNS A record, that particular IP address can change anytime. So when a new IP address is assigned to your instance your visitor cannot see your website because it points to the old IP address which you don’t have control anymore.

To overcome this issue Elastic IP comes in which is a static IPv4 address designed for dynamic cloud computing. With the Elastic IP you can rapidly remap the address to any instance in your account.

Prerequisites

  • A running EC2 Instance. Learn how to create an AWS EC2 instance .

Create Elastic IP address

Login to your AWS management console and navigate to Compute >> EC2 and under Network and security click Elastic IPs.

Create Elastic Ip Address

In this screen click Allocate Elastic IP address .

Allocate Elastic Ip Address

Now a new IPv4 address will get allocated.

Associate Elastic IP address

Once an IP is allocated you need to associate it with the EC2 Instance.

To do so check the checkbox of your IP address and click Actions and choose Associate Elastic IP address .

In the Resource type choose Instance and and choose the instance from the dropdown on the Instance field.

If you have any other Elastic IP address assigned before and you need to re-associate you can enable the checkbox in Reassociation

Click Associate .

Associate Elastic Ip Address

Release Elastic IP address

If you wish to no longer use the allocated IP address you can release it to prevent any unnecessary billings.

To do so check the checkbox of your IP address and click Actions and choose Release Elastic IP address .

Become a Certified AWS Professional with this easy to learn course now.

Now you have learned how to allocate, associate and release Elastic IP address AWS.

How can I change or retain my private IP or public IP address when I do an Amazon EC2 restore in AWS Backup?

During an Amazon Elastic Compute Cloud (Amazon EC2) restore in AWS Backup, I want to change or retain my private or public IP address.

Short description

When you launch an EC2 instance, a private IP address is assigned. A public IP address is also automatically assigned to the instance from the EC2-Classic public IPv4 address pool. Use the Amazon EC2 console or AWS Command Line Interface (AWS CLI) to retain or change the original IP address on a restored Amazon EC2 instance.

  • The auto-assigned public IP address that's associated with the instance changes every time the instance is stopped and started.
  • When an EC2 instance is restored, the private IP address is assigned from the subnet.
  • A newly restored instance doesn't retain the original public IP address. However, you can modify the metadata to use the original IP address.
  • An Elastic IP address is a static IP address that can associate or disassociate from the instance. It can't change or move to the EC2-Classic public IPv4 address pool.

Use the Amazon EC2 console to reassociate your Elastic IP address to the restored EC2 instance

To reassociate the original Elastic IP address to the restored instance, you must associate an Elastic IP address with the instance . The Elastic IP address is then maintained after you stop and start your instance.

Use the AWS CLI to reassociate your Elastic IP address to the restored EC2 instance

Run the following associate-address AWS CLI command:

Note: If you receive errors when running AWS CLI commands, make sure that you're using the most recent AWS CLI version .

Retain a private IP address to the restored EC2 instance

To retain a private IP address before or during the restore, change the primary private IP address in the metadata output.

Complete the following steps:

1.    Run the get-recovery-point-restore-metadata AWS CLI command:

You receive a metadata output similar to the following one:

2.    Edit the metadata output to retain the original PrivateIpaddress , or change the Primary PrivateIpaddress to a different PrivateIpaddress in the NetworkInterfaces metadata field. The following example output is edited to retain the original PrivateIpaddress :

3.    Save the edited metadata as a .json file. Then, run the following start-restore-job AWS CLI command pointing to the edited metadata file to restore the instance with the private IP address:

Related information

AWS OFFICIAL

Editing the serialized part of the metadata wasn't straightforward so I come up with this command:

What this command does:

  • extracts RestoreMetadata
  • removes from it the fields SecurityGroupIds and SubnetId
  • then deserialize and replaces the content of NetworkInterfaces removing NetworkInterfaceId , SecondaryPrivateIpAddressCount , AssociatePublicIpAddress and PrivateIpAddress
  • serializes NetworkInterfaces and creates the json file for the restore job:

YMMV: for example this might not work if the primary ENI has two private addresses.

Thank you for your comment. We'll review and update the Knowledge Center article as needed.

Allocate and associate Elastic IP addresses with AWS CloudFormation

The following template snippets are examples related to Elastic IP addresses (EIPs) in Amazon EC2. These examples cover allocation, association, and management of EIPs for your instances.

Example snippets

Allocate an elastic ip address and associate it with an amazon ec2 instance, associate an elastic ip address to an amazon ec2 instance by specifying the ip address, associate an elastic ip address to an amazon ec2 instance by specifying the allocation id of the ip address.

The following snippet allocates an Amazon EC2 Elastic IP (EIP) address and associates it with an Amazon EC2 instance using an AWS::EC2::EIP resource. You can allocate an EIP address from an address pool owned by AWS or from an address pool created from a public IPv4 address range you bring to AWS for use with your AWS resources using bring your own IP addresses (BYOIP) . In this example, the EIP is allocated from an address pool owned by AWS.

For more information about Elastic IP addresses, see Elastic IP address in the Amazon EC2 User Guide .

The following snippet associates an existing Amazon EC2 Elastic IP address to an EC2 instance using an AWS::EC2::EIPAssociation resource. You must first allocate an Elastic IP address for use in your account. An Elastic IP address can be associated with a single instance.

The following snippet associates an existing Elastic IP address to an Amazon EC2 instance by specifying the allocation ID using an AWS::EC2::EIPAssociation resource. An allocation ID is assigned to an Elastic IP address upon Elastic IP address allocation.

How to set a static internal IP in Ubuntu

Quick links, how to set static internal ip in ubuntu using the gui, how to set static internal ip in ubuntu using the terminal and text editor.

There comes a time when you might have to configure Ubuntu or any other Linux distribution with a static IP address. While you can't change your external static IP address, since it's the one your internet service provider provides, you can change your internal one. This is the IP address used on your network inside your home or office.

Though many tasks on Ubuntu usually require you to visit the terminal app and deal with lines of text, changing your internal IP is easy. You can do this through the settings app and the Graphical User Interface (GUI). Of course, if you want, you can also swap things out by going through the terminal. Here's how.

Without any technical know-how or knowledge, you can set a static IP in Ubuntu through the settings app. Just note, you will have to use the terminal once to find a range of IP addresses that you can assign. Once you do that, you just tap the Windows Key or the Superkey on your device and search for Settings . Once the app is open, proceed with the steps below.

  • If you're connected to the internet via Wi-Fi, choose Wi-Fi . If you're connected via Ethernet, select Network.
  • Once the interface is open, click the settings icon next to the network you're connected to.
  • From the list of tabs at the top, choose IPv4.
  • Under ipv4 method, be sure to choose Manual.
  • Under Addresses, enter the IP address, the Netmask, and the Gateway you want to use. For finding IP addresses that'll work on your network, you can proceed with the steps below.
  • Open a terminal session. With Ctrl, Alt, and T. Install net-tools with the command sudo apt install net-tools.
  • In this case, we have an inet of 192.168.1.176 and a netmask of 255.255.255.0. We can enter those numbers and can calculate the usable range using this website .
  • When you've calculated the usable range of addresses, choose a valid IP address that falls within this range. Then, you can click Apply at the top.

Any changes you apply will automatically go into effect. If you want, you can also use the terminal to confirm your IP address. Launch it with Ctrl, Alt, and T on your keyboard. Once launched, enter the command ip addr or ip a . You should see an interface IP address listed.

If you're a bit more technical and want to set a static IP in Ubuntu using the terminal, that is possible. You'll have to edit some lines of text and go through a few extra steps, but here's how:

  • Display information about your network. Use the command nmcli connection show. You'll see a network name, a UUID, a Type, and a Device. If this package isn't installed (though it should be, as it comes preinstalled with Ubuntu), then run sudo apt-get install network-manager
  • Note down the range of IP addresses you'll be able to use. Use the command ip addr to find out your machine's current IP address. This tutorial assumes that your network adapter is called enp0s3. If it isn't, then look for the correct one and also change the interface names in the subsequent commands. In the above example, we have an inet of 10.0.2.15, with the /24 denoting that the network uses a 255.255.255.0 subnet mask. In most cases, your usable network range will be whatever is in the first three places of the internal IP address, and then any unused number on your network between 1 and 255 in the last section. For example, we can use 10.0.2.16. If you're unsure, you can enter the subnet mask and your internal IP address into this website to calculate the usable range.
  • Note the IP address of your default gateway with the command ip r. In our example, it's 10.2.2.2.
  • Next, we'll add a new static connection option. Run the following command, making sure to change the numbers after "ip4" and "gw4" depending on your network conditions. These are the IP address you want to change your machine to and the current default gateway, respectively. sudo nmcli con add con-name "static" ifname enp0s3 type ethernet ip4 10.0.2.13/24 gw4 10.0.2.2 In our case, we do the following.
  • Set your DNS, manual DHCP (so, a static IP), and enable the connection. You can do that by running the following commands in succession. nmcli con mod "static" ipv4.dns "1.1.1.1,8.8.8.8" You can swap out the DNS servers above for whatever you want, they are in order of primary and secondary. nmcli con mod "static" ipv4.method manual; nmcli con up "static" ifname enp0s3 Once done, you can run nmcli con show to see if the new connection is enabled. If the output above looks like yours, then you're ready to go!

Setting complete

That's all you need to set up a static IP in Ubuntu. It doesn't take much effort. Remember, we're always writing about Linux, so you can check out our guide to the best Linux laptops should you need one.
