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

with BIND9, you just have to install a zone by that name, containing an A/127.0.0.1 for every name you're seeing queries for. that'll get action by whoever made the mistaken delegation toward your server... (i promise.) -- Paul Vixie
