Actually, dig is a part of the BIND distribution and does pretty-much the
same thing that nslookup does.

dig checks only the authoritative server for the domain in question
(recursively if necessary just like nslookup). You can point dig at other
nameservers just like you can nslookup.
dig is more useful for scripting queries for certain types of information,
but in the way you're using it (inverse query) it's no more or less useful
than nslookup - it just hands back the authority and additional sections
- info that you have to ask nslookup for specificly (as well as query
statistics - which aren't useful in this case.) nslookup is designed to
be run interactively, dig is designed to be scripted.
Go into nslookup and do "set d2" and you'll see more information about a
query than you probably ever wanted to as a response to any nameserver
query you run.
