Dear Chris, Thanks for your quick response. But my concern is; why this query is actually started going to AS112 servers. Is it because my DHCP servers do not maintain PTR record zone for all internal IP address? I need to have a solution to stop this query at host level instead of adding entry in DNS server Regards papdheen M
