How should my zones be sat up? Thanks. In order to set up a reverse DNS lookup, you need to create a special zone. The name of the zone is the first 3 octates (in freverse order) and in-addr.arpa. So in your case, your reverse lookup zome would be called 76.77.216.in-addr.arpa Once you have created this zone, add records to this zone. Use the fully resolved host names and their IP. In order to check if your reverse lookup is working, do a ping to the IP address with "-a" switch. So in your case it would be ping -a 216.77.76.245 Hope this helps.
