Possible to copy and entire domain?

[Brian Johnson]

I've just started setting up DNS and have been able to create an internal view and
hook into DHCP to dynamically update my domain

I would like to set up a second domain name that is just a duplicate of the first
including all the dynamically updated ip addresses

I had trouble coming up with a good description to search by and couldn't filter
the proper answer out of all the search engine responses

Is this possible?

How do I do it?
