Are the servers authoritative for your reverse domain as well? A
misfeature of nslookup is that before it sends to query you asked it
for, it first does a reverse lookup of the server IP, so that it can
report the name of the server it's using.

But if there's only one server, it will apparently use it regardless of
the error.

If you're trying to troubleshoot DNS, you really should use "dig" rather
than "nslookup".
