Assign IPv6 Address to AWS EC-2 Instance

By default instance does not have an IPv6 Address. If you want to associate IPv6 address to your EC-2 instance, you need to associate IPv6 CIDR block to VPC and Subnet of the instance first, then add IPv6 address to the instance.

Here is the step by step procedure to associate an IPv6 address to already running instance:

Go to https://console.aws.amazon.com and click on EC2. Click on your EC-2 then get VPC and Subnet from description details.

    Hello,
    Thanks for the easy guide
    I did all of this but it is still inaccessible

    Thanks Ismail, your step-by-step instructions were great! Minor change would be that in step 3 you leave the text box empty (shows as auto-assign). Thanks for taking the time to document, the official docs are too technical and not easy to follow.
