This sounds very like my AD domain ;-)

As long as your servers are in the same dns domain, this should work as
before, If you think about it, every DHCP client before it is joined to
the domain works this way.

Just because a computer (or printer etc) gets its IP from a DHCP
server running on an AD DC, doesn't mean it has to be joined to the
domain.
