bind on a LAN?

[Jim]

whats the best way to host a dns solution on a LAN if my bind server is not
going to take any queiries from the outside world and is hosted behind a
firewall?
I want to be able to control clients somehow on my lan so i'd need to
control atleast 1 zone on my server. Do you recommend creating a fake domain
name for my lan? like (ie. mylan.internal-domain.com). Or is NetBios the
best way to go here? whats the best way to do this?

Thanks
-Jim
