kiastick.app Has IPv6

A (IPv4)	104.21.28.78 172.67.144.227
AAAA (IPv6)	2606:4700:3035::6815:1c4e 2606:4700:3033::ac43:90e3

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: kiastick.app has 2 IPv6 addresses and answers on every one we tested.
    2606:4700:3035::6815:1c4e: answers (TCP 443)

- 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).
