Accessing an AWS hosted backend via IPv6
Reaching my API via IPv6 is not something I considered a high priority, but due to my prior experience with AWS I took the ability for granted. Recently I found out that it’s not as simple as I thought, since new AWS accounts do not get access to EC2-Classic, and to my surprise EC2-VPC has only recently started supporting IPv6, and only in us-east-1 with several limitations.
While not as trivial as I thought, there are simple solutions available, so I will describe the how and why of a couple of ways which we recently used at Takumi.
