Private and Public Network DNS

[Kevin Darcy]

This can be handled using normal "split DNS". You could run multiple
instances on the same machine, if you want -- an "internal" instance
which only listens on the internal and loopback interfaces, and an
"external" instance which only listens on the external interface. Search
the archives for recent messages detailing how to do this. Each instance
would have a separate version of "foo.com". Only the internal instance
would have the 10.x.x.x addresses in it.
