• IPv6 enablement checklist for a website

  Enable IPv6 in this order: address and firewall on the host, the server listening on [::] (nginx's IPv6 listener accepts only IPv6 by default, so keep the IPv4 one), a test over curl -6 against the address, then the AAAA record, then monitoring that probes each address family separately; Happy Eyeballs clients hide a broken IPv6 path behind a delay, while simpler clients fail outright.
