I don't understand what you're trying to do here. Are you going to block your
*inside* users from asking about your public domains? If a public domain is a
"shadow" of an internal domain, this is not an issue if you configure your
internal servers properly so that they'll never be forwarding queries for that
domain. Conversely, if the public domain is completely separate from any
internal domain, then you'd probably want your internal clients to be able to
see it.
