In article <CAHw9_i+UsV9NkuPM4KYBZhO7_J78MkUEyVR3fr=vOX-vsjJeUA@mail.gmail.com> you write:
>What if you *only* have glue, and no authoritative answer / server?

Based on my recent analysis of TLD zones, yes if the zone is managed by
Afilias, or if you have friends at Nominet.  Otherwise not so much.

For wow4dns.com it looks pretty normal other than that your NS is lame.

Here's what's in this morning's .COM zone file, but I assume you've updated the NS since then:

WOW4DNS NS NS1.AUTH-SERVERS.NET.
WOW4DNS NS NS2.AUTH-SERVERS.NET.

Your registrar record and the live .COM NS say:

$ dig @g.gtld-servers.net. wow4dns.com a
