dnalenses.org Has IPv6

A (IPv4)	104.21.10.78 172.67.144.236
AAAA (IPv6)	2606:4700:3030::ac43:90ec 2606:4700:3032::6815:a4e

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

- Mail servers (MX) have IPv6: No MX records, so mail goes to the domain's own address (implicit MX). It 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).
