What's keeping georgetown.edu from an A

  1. Mail servers without IPv6
    usb-smtp-inbound-2.mimecast.com, usb-smtp-inbound-1.mimecast.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.
  2. Nameservers without IPv6
    ns6.georgetown.edu, ns4.georgetown.edu, ns5.georgetown.edu all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
