theuapregistry.org Has IPv6

A (IPv4)	104.21.44.117 172.67.199.144
AAAA (IPv6)	2606:4700:3037::ac43:c790 2606:4700:3031::6815:2c75

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

Readiness grade A: Website, mail and DNS all work over IPv6.
- Website over IPv6: theuapregistry.org has 2 IPv6 addresses and answers on every one we tested.
    2606:4700:3037::ac43:c790: answers (TCP 443)
    2606:4700:3031::6815:2c75: answers (TCP 443)
- Mail servers (MX) have IPv6: Every mail server has an AAAA record.
- Nameservers have IPv6: 2 of 2 nameservers checked have an AAAA record, so IPv6-only resolvers can look the domain up.

Reachability = a TCP connection opened on port 443 (or 80).
