Even if the only thing that supported IPv6 was ELB, and everything else was
still IPv4 internally, that'd put a lot of traffic on IPv6 very quickly, and ELB is something *entirely* controlled by AWS (you CNAME to an ELB FQDN, AWS
takes care of resolution and proxies a TCP connection to your instance).

elb ipv6 support has been in place for some time (may 2011 for us east and ireland)

"IPv6 support is currently available in the following Amazon EC2 regions: US East (Northern Virginia), US West (Northern California), US West (Oregon), EU (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Singapore).?

That use of CNAMES by AWS ELB poses a problem for websites setup as domainname.tld and also have MX records for the domain. I ran into this problem recently with an organization that moved their website to AWS and found they had to use the Amazon real servers' IP address in their DNS instead of the ELB hostname. Unfortunately we were told the real server doesn't have an IPv6 address. Only the load balancer does.
