I usually make an "internal.domain.com" subnet, and then duplicate
all of the relevent server names with internal addresses. So, I
have www.domain.com as 1.2.3.4 and www.internal.domain.com as
10.2.3.4. Alternatively, you could set up views in named.conf so
that internal requests for www.domain.com get 10.2.3.4 and external
requests see 1.2.3.4. It's a bigger pain to maintain that way, IMHO,
but it keeps your internal network structure hidden.

I don't think there is a "correct" way to set that stuff up. I'm
personaly partial to not using fake TLDs, though. What if you had
decided to use ".biz" or ".tv" 5 years ago (or however long ago)
before those were valid TLDs? That network that was set up all of
the sudden may conflict with a real TLD. Using a subdomain has no
such problem... :)
