What's keeping tt00055.shop from an A
tt00055.shop is an alias of 5ngu1464fpb3gu.dns.foocname.cc, which has no IPv6 tt00055.shop is a CNAME, so it can't also have its own AAAA record. Ask whoever runs 5ngu1464fpb3gu.dns.foocname.cc to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
Add IPv6 for www.tt00055.shop www.tt00055.shop has no AAAA record. Get www's IPv6 address from whoever hosts www and add it as an AAAA record. If the same server already serves both names (and its certificate covers www), you can reuse tt00055.shop's AAAA record(s) for www. How to add an AAAA record
Mail servers without IPv6 Your domain's mail goes to its own address, which has no AAAA record.
Nameservers without IPv6 a.share-dns.com, b.share-dns.net all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
Visitors on IPv6-only networks (many mobile carriers) can still reach it, but only through a translator their carrier runs (NAT64). The site itself has no IPv6 address — and you can't make one up from the IPv4. Why some hosts don't offer it
