Web Server configuration

Cute Puppy asked:

I have a simple concept question regarding to the hostname configuration on DNS server.

I am trying to set-up a webserver where there is an internal address and external address.

Server name: Puppy.test.com
External address:
Internal address:

Does that mean I to have to give the external DNS server with puppy.test.com to point to
and internal DNS server with puppy.test.com to point to

In order to get both address resolvable by the DNS server? (both internal and externally)

My answer:

Yes. This is called split horizon DNS, and is implemented in Bind with its views feature.
