What I was basically asking for was a "silently drop queries for X-domain" option. But one doesn't exist in bind.
take a look at www.as112.net to see what happens to queries for 10.in-addr.arpa and its brothers. you can easily set up a zone
There weren't rfc1918.
Doesn't matter. But in order for this trick to work: - The things sending you queries must be able to receive your replies. I believe you said that source addresses are spoofed, so this may not be the case. - The things sending you queries must be smart enough to follow the NS referral in the response. If I wanted to silently drop DNS queries based on the query name, I might use FreeBSD's divert socket and a Perl script to examine the queries. Not sure well that would scale though. Duane W.
