If your nameservers answer nslookup properly, then you have no problem. If DIG
returned different results, the nameserver DIG was using was different (or it used the
same nameserver, but queried it at a different time, when there was different
information there).
It is important to remember to use the proper server(s). First, check to see what the
root servers are using (query a root server for the NS records for your domain).
Then, make sure to use EACH server in nslookup (or DIG or whatever tool you choose to
use). If you use nslookup on one of your nameservers, it is quite possible that
another nameserver may return different results.
I'm starting to put together a detailed set of instructions for people to use to check
out their DNS entries to make sure everything is correct (temporarily at
http://110.net/~rscott0/dns/ ), that explains step by step how to make sure all is
well.
