IPv6 readiness

Website, mail and DNS all work over IPv6.

Website over IPv6 allthreads.org has 2 IPv6 addresses and answers on every one we tested. ✓ 2606:4700:3032::ac43:aab4 answers · 443✓ 2606:4700:3033::6815:4794 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. amir.ns.cloudflare.com ✓melinda.ns.cloudflare.com ✓	yes

allthreads.org Has IPv6

A (IPv4)	104.21.71.148 172.67.170.180
AAAA (IPv6)	2606:4700:3032::ac43:aab4 2606:4700:3033::6815:4794

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