Re: Bounce Utility

dan,

the "views" feature of BIND 9 handles this problem nicely.

6.2.20. view Statement Definition and Usage
The view statement is a powerful new feature of BIND 9 that
lets a name server answer a DNS query differently depending
on who is asking. It is particularly useful for implementing
split DNS setups without having to run multiple servers.
Each view statement defines a view of the DNS namespace that
will be seen by a subset of clients. A client matches a view
if its source IP address matches the address_match_list of
the view’s match-clients clause and its destination IP address
matches the address_match_list of the view’s match-destinations
clause. If not specified, both match-clients and
match-destinations default to matching all addresses. A view
can also be specified as match-recursive-only, which means
that only recursive requests from matching clients will match
that view. The order of the view statements is significant —
a client request will be resolved in the context of the first
view that it matches.
Zones defined within a view statement will be only be accessible
to clients that match the view. By defining a zone of the same
name in multiple views, different zone data can be given to
different clients, for example, "internal" and "external"
clients in a split DNS setup.
