HTTPS over IPv6 · not part of the grade yet
Loads over IPv6 with a valid certificate after 1 redirect: HTTP 200.
https://php.net/ via 2a02:cb40:200::1ad → 301https://www.php.net/ via 2400:52e0:1a04::1310:1 → 200

What's keeping php.net from an A

  1. Mail servers without IPv6
    php-smtp4-ip4.php.net has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
