Reverse Zone
Is it normal when provider doesn't delegate you thereverse zone, that's why you cant reverse resolve the IP. If you run:
nslookup ns1.gdznet.com ns1.gdznet.com
nslookup 66.220.13.162 ns1.gdznet.com
Does anyone have a clue how to fix this?
Is this a misconfigure in the box or the ISP side?
