2).Go to EC2 Dashboard → Elastic IPs (in the left sidebar).

3).Click Allocate Elastic IP address.

Choose Amazon’s pool of IPv4 addresses and Click Allocate.

4).Now you’ll see the new Elastic IP in the list.

Step 2: Attach Elastic IP to an EC2 Instance

1). Select the Elastic IP you just created and Click Actions → Associate Elastic IP address.

2). Under Resource type, choose Instance.
3). Select your EC2 instance from the dropdown.
