Creating a DNS "dead Zone"
I have a situation where a dns client is bombarding my dns server with dummy requests to the point that it seems to be running up my CPU to almost 100% utilization. Due to limitations on the client I am unable to stop the requests from being generated right now.
Is there a way for me to point these dummy requests to a NULL address ( if there is anything like that ) that would prevent further requests ?? or any other solution you would recommend.
The requests usually have the name <whatever>.xyz.com ( so the xyz.com is common to all the dummy requests )
Any help would be appreciated... thanks
