How do I block a specific DNS query (IP address) in a CENT/OS conputer.

Asked by OOsorio in Linux Administration, Domain Name Service (DNS), Linux Networking

Tags: CENT OS (Linux)

This particular computer is sending out a bogus DNS query to our DNS windows 2003 sever. I would like to block the query at the source. How can this be done?
