You don't say what name server you're running or if you have local access to it.
If you're running a recent version of BIND, try running:
Code:
/usr/sbin/rndc stats
/usr/sbin/rndc dumpdb
After the commands are complete, have a look in your zone files directory (usually /var/named, check the directory entry in the options section of /etc/named.conf to be sure though) for the files named.stats and named_dump.db.
