First of all, don't hide the real names and IP addresses. It makes it
impossible for people to diagnose the problem. For instance if you'd
supplied this data, I could have queried the name servers. And use dig
instead of nslookup for DNS troubleshooting. nslookup is an awful tool.

There's nothing wrong with the output of nslookup, [Well as far as the
usual unhelpful output format of nslookup goes, there's nothing
wrong.] You made a query and got a non-authoritative answer. That's
what usually happens when you ask a name server about some name in a
zone when it's not master or slave for that zone. The name server goes
off and resolved the query, caches the result and returns a
non-authoritative answer because it's not an authoritative source for
that answer.
