IPv6 readiness

Website, mail and DNS all work over IPv6.

Website over IPv6 docs.tomo.inc has 2 IPv6 addresses and answers on every one we tested. ✓ 2a06:98c1:310d::6812:282f answers · 443✓ 2606:4700:4401::ac40:93d1 answers · 443	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 2 of 2 nameservers checked have an AAAA record, so IPv6-only resolvers can look the domain up. chase.ns.cloudflare.com ✓pearl.ns.cloudflare.com ✓	yes
