Netware 6.0 sp3

I need to have 500 different MAC addresses able to get a DHCP IP address
from 3 different subnet pools. I know I can configure the Wireless Access
Point to only allow those addresses to connect but I'd rather not have the
AP's handing out the addresses and I'd rather not have to update each
access point.

Any ideas how I can accomplish this within Novell's DHCP?
