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 that will just confuse and make errors for whoever queries it: @ SOA localhost hostmaster.localhost NS localhost localhost A 127.0.0.1 * MX 0 localhost A 127.0.0.1 (the specific name "localhost" is nec'y because glue searches aren't required to find wildcards.) if you put a zone like that in place on a server that's receiving unwanted queries for some zone, they will soon stop, or not. you win either way -- the queries stop, or you laugh your ass off. -- Paul Vixie
