It's not clear to me from your question whether you are talking about
a networking issue, or a dns answer issue. Can you clarify whether or
not you are trying to get named to send its answers out on the same
network as the question came from (which I believe it should do
automatically); or whether you are asking for named to change its
answers depending on what network the question came from.

If it's the latter question, the answer you already got here about
views is the right one.

hope this helps,
