What's keeping focus.de from an A

  1. www.focus.de is an alias of a1707.g.akamai.net, which has no IPv6
    www.focus.de is a CNAME, so it can't also have its own AAAA record. Ask whoever runs a1707.g.akamai.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
