Oversimplified DNS - A record (address)

Oversimplified DNS - A record (address): " Zone Transfer. This will show you every record in your DNS. However, your nameservers may refuse zone transfers to any computer except the secondaries nameservers. In that case, you'll have to go to one of the nameservers, and get the master zone file.

To do a zone transfer in NSLOOKUP, first type "server nameserver.example.com", where "nameserver.example.com" is one of your nameservers (try the primary nameserver first, if it doesn't work, try the secondary(s)). Then, type "ls -d example.com". If you have a lot of entries, you might want to save it to disk using "ls -d example.com > filename.txt", where filename.txt is the name of the file to save to "
