This is when you use the "views" part of bind 9.  It can return a
different dataset based on the requestor's IP.  You can have requests for
internalmachine1.foobar.org, internalmachine2.foobar.org, etc resolve to
one IP address when looking at it from the internet, but have them all
resolve to their 1918 address when coming from your internal network.
