HTTPS over IPv6 · not part of the grade yet
Redirects to www.reddit.com, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all.
https://reddit.com/ via 2a04:4e42:600::396 → 301https://www.reddit.com/ · redirects to www.reddit.com, which has no IPv6 address
problem
 Load reddit.com over IPv6 from up to six other places — a second opinion.

What's keeping reddit.com from an A

  1. www.reddit.com is an alias of reddit.map.fastly.net, which has no IPv6
    www.reddit.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs reddit.map.fastly.net to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
  2. A redirect leads off IPv6
    Redirects to www.reddit.com, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all. Give the redirect target IPv6 too, or redirect somewhere that has it.
