HTTPS over IPv6 · not part of the grade yet
Redirects to amazon.com, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all.

problem

What's keeping petersenhome.org from an A

A redirect leads off IPv6
Redirects to amazon.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.
Mail servers without IPv6
mx00.ionos.com, mx01.ionos.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.
