yes
Mail servers (MX) have IPv6

Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.
ns1.dns-redirect.com ✗ns2.dns-redirect.com ✗
no
HTTPS over IPv6 · not part of the grade yet

What's keeping loser.cool from an A

  1. Nameservers without IPv6
    ns1.dns-redirect.com, ns2.dns-redirect.com 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.
