HTTPS over IPv6 · not part of the grade yet
Redirects to www.bbc.com, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all.
https://bbc.com/ via 2a04:4e42::81 → 301https://www.bbc.com/ · redirects to www.bbc.com, which has no IPv6 address
problem

What's keeping bbc.com from an A

  1. www.bbc.com is an alias of bbc.map.fastly.net, which has no IPv6
    www.bbc.com is a CNAME, so it can't also have its own AAAA record. Ask whoever runs bbc.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.bbc.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.
  3. Mail servers without IPv6
    cluster8.eu.messagelabs.com, cluster8a.eu.messagelabs.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
