Because the clients would be dynamic.  And that was what I was asking.
About having static ip's in a zone that is handled by dynamic updates.

If I have 100 employees in my company and 4 printers and the network is
divided into 4 subnets with a printer in each.  If 90% of printer traffic
comes from inside the subnet it resides in, it helps control traffic (as
opposed to sticking all the printers on the same subnet).

This is basically what I wanted to do:

When I configure a PC, I'll give it a name (no big deal since I have to
configure Client Access for AS/400 emulation and have to give it a "device
ID".  Figured I'd just use the same name for the hostname the client tells
DHCP it wants).

DHCP would hand out an IP address, take the requested hostname, and stick
them both in DNS.  This way it would be possible to track user traffic no
matter what their IP address is.  Well, all printers are network attached
and I would want them to have static IPs and not to change and I was
inquiring on how to do that since it says that you can't have static content
in a dynamic zone.

As for multiple zone's on the same subnet, I am not grasping how that would
be done.
