What's keeping cdptaxservices.com from an A

  1. Mail servers without IPv6
    mx2.dreamhost.com, mx1.dreamhost.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
    ns3.dreamhost.com, ns2.dreamhost.com, ns1.dreamhost.com 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.
