You are probably looking for split DNS. However, you must be aware
that "host not found" (NXDOMAIN) or "no data" (NOERROR with
ancount==0) is not a failure. The query was answered successfully.
BIND 9 has views which allows you to do pretty much what you want with
as little hassle as possible.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
