RE: DNS requests and Bandwidth

From: aljuhani

One way was to block requests from that DNS IP but that was not practicle as many users on that DNS won't be able to communicate with our server.

so What is the best way to prevent DNS queries consuming bandwidth.

Run an authoritative-only DNS server that won't respond to queries for domains it doesn't handle. tinydns from http://cr.yp.to/djbdns.html would be an example. David
