I have an ELB with ipv6 AAAA DNS configured on route 53. The problem is that the tests I used tell me it's not ok (I don't have an ipv6 connection for testing):
AFAIK I don't need to configure nginx on instances for ipv6 as it should be handle by the ELB. But it's not apparently !
Note: I use the dualstack url in route 53 configs.
AAAA
record with IPv6 addresses. The issue is that the ELB itself, managed by AWS, doesn't listen on IPv6 addresses. Only "EC2-Classic" ELBs currently support IPv6 (and IPv4) addresses. And unfortunately, AWS does not currently support assigning IPv6 addresses directly to EC2 instances, so you cannot run your own EC2 instance with a publicly accessible IPv6 address to workaround the issue. You're not alone in this; many others would very much like AWS to support IPv6 properly.
