AWS has supported IPv6 on the edge for several years. What they haven't supported is IPv6 internally. I sometimes wonder if it's because they are running a home-built IP stack on custom gear, and just haven't bothered to adding IPv6 yet.

The neither the newer VPC ELBs nor CloudFront support IPv6. Not even the Route53 DNS servers have an IPv6 address. With very few exceptions, there is no IPv6 support on AWS, internal or external.
