[dns-operations] The strange case of fox.com

[Stephane Bortzmeyer]

Sometimes, there are domains where you wonder how they work. fox.com
has a NS RRset in the zone which is larger than 512 bytes (legal,
that's not the biggest problem) where _not one_ of the name servers
reply (half REFUSED, half timeout).

How can people browse <http://fox.com/>? Because the NN RRset in the
parent zone is completely different, and made of working name
servers... THere is apparently not one name server in both sets.

So, I believe Zonemaster is right to complain
