Delegation of DHCP blocks within same server?

[John Cole]

Question:

[Apologies for asking something that strikes me as most likely obvious, but just outside my grasp today - and of course, I haven't been able to find similar situations to borrow from on the web]

Within a private /16 in.addr zone, I've got two /24 blocks of (contiguous) DHCP issued addresses.  Presently DHCP updates these addresses which are intermingled with all other static addresses in the /16 space.  For the purposes of a cleaner zone file and less traffic between slave servers, what's the best technique to break out the two dhcp issued address spaces?

My presumption is that the /16 zone remain a single zone file, with sub-delegation of those two /24 blocks.  As I've only done delegation to other name servers, is this both possible/recommended to be done in one bind instance?  Ideally, delegating a /23 seems to strike me as the right thing to do.  Of course, my blocks don't fall on a /23 boundary.  *eye roll*

For a concrete example:

10.0.0.0/16 is presently handled by a single zone file.
10.1.3.0/24 is DHCP issued
10.1.4.0/24 is DHCP issued

What do the experts recommend as the best method to split these into 1-3 different zone files on the same name server.

Thanks much for the assistance,
jc
