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
4 of 4 nameservers checked have an AAAA record, so IPv6-only resolvers can look the domain up.

Nothing keeping you from an A

  1. The certificate served over IPv6 is wrong
    The certificate served over IPv6 at 2600:1408:a:203::170f:399 isn't valid for static.cootlogix.com: CERT_HAS_EXPIRED. Often the IPv6 address points at a different server (or an old one) than IPv4 does. Make sure 2600:1408:a:203::170f:399 serves the same certificate as your IPv4 address.
