If you configure a zone to be authoratitive on a name server it will
override any zones that are on the outside network. In otherwords, if you
configure a zone called yahoo.com and in the hosts file put www.yahoo.com
to point to 192.168.1.80 then it will override the www.yahoo.com most
people get to. Master Zones override Hint Zones in other words.
