mytatami.app Has IPv6

A (IPv4)	172.67.182.253 104.21.51.167
AAAA (IPv6)	2606:4700:3037::ac43:b6fd 2606:4700:3033::6815:33a7

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

- Website over IPv6: mytatami.app has 2 IPv6 addresses and answers on every one we tested.
    2606:4700:3037::ac43:b6fd: answers (TCP 443)
    2606:4700:3033::6815:33a7: 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).
