What is the AWS Elastic IP address?

Amazon Web Services (AWS) should be a common word for you if you are working in the IT sector. It is the world’s largest cloud service provider. Top brands, such as Netflix, Twitch, and LinkedIn, use AWS but the most beautiful thing about AWS is that it is cheap; you pay for what you need, so everyone can use it. AWS provides a wide range of services. In this blog, we will learn about the following:


What is AWS Elastic IP?

An Elastic IP (EIP) address is more of a static IPv4 address that is designed for dynamic cloud computing. The main purpose of these IPs is to mask the failure of software or instance from your AWS account.

This is achieved by remapping the address to another instance, which is available in your account as quickly as possible. An IP address is automatically allocated to your AWS account and it will be yours unless you decide to release it. On the other hand, you have the chance to specify the IP in a DNS record to your domain. This will make sure that the specified domain points to your instance.

This address is reachable from the internet like any other public IPv4 address. You can associate this IP address with your instance if your instance does not have any public IPv4 address to enable communication from the internet to the instance. At present, the AWS EIP does not support addresses for IPv6.

AWS Elastic IP Pricing

AWS imposes a small, hourly charge to make sure that the provided IP addresses are used efficiently. There are a few conditions that are applied to a business to acquire the pricing charges. They are as follows:

So, the pricing for these AWS EIPs is US$0.005 per hour for IPs that are not assigned to any running instances. For IPs that are remapped more than the limit, the cost is around US$0.10 for every remapping that occurs.

Characteristics of AWS Elastic IP

Now, let us see some basic characteristics of Elastic IPs:


Difference between Elastic IP, Public IP, and Static IP

The internet recognizes you by your public IP address. A public IP address is an address that your internet-connected device uses to communicate with the rest of the internet.

IP addresses that do not change are known as static IP addresses. They’re widespread in business and cloud computing, which is why Amazon’s Elastic IP framework contains them.
A static IP address is beneficial for a variety of reasons. For DNS searches in cloud computing, a static IP address is advantageous. The process of loading content can be hampered if IP addresses change.

Elastic IP is utilized for dynamic cloud computing in the AWS cloud environment, according to AWS. It’s crucial to make this distinction – If your AWS instance goes down, you’ll want to keep your IP address and preserve contact with your account.

Therefore, an Elastic IP is a hybrid of a public and a static IP address. It enables you to keep advertising AWS instances within your AWS network infrastructure.


Working of AWS Elastic IP

Now that you have a basic idea of what AWS EIP is, let us see some tasks that you will do in the cloud.

Describe your Elastic IP Address

To describe your IP address, follow these steps:

Tag an Elastic IP Address

You can use tags to differentiate among your IP addresses by following the given steps:

Associate or Disassociate an Elastic IP Address with an Instance or Network Interface

For associating the IP address with an instance or network interface:

For disassociating the IP address with an instance or network interface:

Releasing an Elastic IP Address

You can release your unwanted elastic IP addresses to avoid the charges for them. To do that, follow the below-mentioned steps:

Limitation of Elastic IP

Even though Elastic IP is simple to use, it has some limitations. We all know that public IPv4 addresses are scarce internet resources. So, by default, AWS limits the maximum number of Elastic IP addresses per region to five. The main purpose of these IP addresses is to mask the failure instances by remapping the addresses to other instances so that AWS recommends using IPs for that and for other internode communication.



I hope this blog gives you insight into what AWS Elastic IPs is all about. Cloud computing is the field that has and will have a lot of job openings all around the world in the near future. So, it is up to you to grab the opportunity and become a cloud expert and earn more than other IT jobs.
