What's keeping media.cdu.de from an A

  1. Give media.cdu.de and www.media.cdu.de an IPv6 address
    Ask your hosting provider for the site's IPv6 address (or the hostname to point at), then publish it as an AAAA record. If your host doesn't offer IPv6, a proxy that does can sit in front. How to add an AAAA record
  2. Mail servers without IPv6
    Your domain's mail goes to its own address, which has no AAAA record.
