I think the original poster is confusing a couple of things.

	* bind 
	* subnets
	* subdomains
	* private networks .vs. routable networks.

In your Bind admin reference manual look for discussions on
internal and external name servers.   No external facing name server
can give a good answer that contains a private network ( i.e., , etc.)  this just does not work.

Also when slicing and dicing private network numbers into subnets make sure
that there is no overlap.  If the primary server is responsible for the
entire class A ( network funny things will happen on your sub{domain,nets}
as there is no clarity about the authority should you want sub{domains,networks}.

Routing is another issue where subnet masks need to be watched with care.
Is the intention to route or NAT traffic.

Is there a mix of Windows, Linux, DHCP, fixed IP addresses , PXE, NFS  involved.

Step one:
	do host names resolve correctly?
	does routing work... (ping)?
