	It is not good practice return addresses to internal space
	to an external query.

	The usual way around this is to run two instances of a nameserver
	on one machine.

	With BIND 8 this requires two or more interface to listen-on, virtual
	interface are fine.  One for internal clients one for external clients.

	With BIND 9 you can achieve the same effect by using views on one
	interface.
