problem

What's keeping danblack.pro from an A

www.danblack.pro is an alias of danblack.format.com, which has no IPv6
www.danblack.pro is a CNAME, so it can't also have its own AAAA record. Ask whoever runs danblack.format.com to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
A redirect leads off IPv6
Redirects to www.danblack.pro, 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.
