yes
Mail servers (MX) have IPv6
No MX records, so mail goes to the domain's own address (implicit MX). It has an AAAA record.		yes
Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.

 Load phin.land over IPv6 from up to six other places — a second opinion.

What's keeping phin.land from an A

  1. Nameservers without IPv6
    nsa1.squarespacedns.com, nsa2.squarespacedns.com, nsa3.squarespacedns.com, nsa4.squarespacedns.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.

Browsers on dual-stack networks will usually pick IPv6 here (the "Happy Eyeballs" algorithm races both and prefers v6).
