 Load 4digital.dev over IPv6 from up to six other places — a second opinion.

What's keeping 4digital.dev from an A

  1. Add IPv6 for www.4digital.dev
    www.4digital.dev has no AAAA record. Get www's IPv6 address from whoever hosts www and add it as an AAAA record. If the same server already serves both names (and its certificate covers www), you can reuse 4digital.dev's AAAA record(s) for www. How to add an AAAA record
  2. Mail servers without IPv6
    mx1.mail.ovh.net, mx2.mail.ovh.net, mx3.mail.ovh.net 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.
