Is this DHCP assigning host names and IP addresses?
If so it is possible (and advisable) to take advantage of
DHCPs ability to associate a physical MAC address with 
an IP address/ host name.   This lets you correctly track logs 
and hardware errors should you need to.

I like to leave a small handfull of addresses that can be
assigned on the fly -- this makes it easy to connect a new
system and configure it.  It also makes it easy to connect
a laptop and fix things should I need to.
