What's keeping appier.net from an A

www.appier.net is an alias of s3-website.us-east-1.amazonaws.com, which has no IPv6
www.appier.net is a CNAME, so it can't also have its own AAAA record. Ask whoever runs s3-website.us-east-1.amazonaws.com to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
