Bind 9 ext and int zone

[Nick Allum]

So I make myself authorative for the subdomain only and the root domain
will be looked up externally?

Example

Yellow.com is an external domain but we setup the subdomain
dev.yellow.com internally. So are are you saying that when a look up is
made for dev.yellow.com it will find it internally first and that if
they look up say www.yellow.com it will know to go externally right
away.

If you make your server authoritative just for the subzones qa.test.com 
and dev.test.com, it will recurse out to the Internet for everything 
else in test.com.

Another solution is to make your server authoritative for test.com, and 
put NS records in the zone for all the outside names, e.g.

www IN NS <outsideNS1>
    IN NS <outsideNS2>

If any new names are added to the outside nameserver you'll need to add 
them here in parallel, but you don't need to update your nameserver when

changes to existing entries are made (e.g. if www's address changes).
