Do I need to setup a “zone” for every domain name that is visible to the outside world?

Question

I have a quick question. I just setup DNS on one of our Ubuntu servers using Bind9. Now my question is do we need to setup a "zone" for every domain name that is visible to the outside world? Or is there another option? What are the best practices for setting up different domains in Bind9?

A little while after I posted this message I found the answer posted in the Ubuntu forum. :) For every top level domain a "zone" does in fact need to be created. Here is the URL for anyone interested:
