No more static IPs

[Bryan D. Brown]

Hello, everyone:

I recently set up DHCP to assign IP's based on hardware address. 
However, it seems that some folks on our network are still using 
static IP assignments, something I would like to put an eand to for a 
number of reasons (we have a few computers that obtained their own 
IPs by looking at the computers around them and trying one until it 
took).

Is there a way to do this without using iptables. I have tried 
assigning all non-used IPs to pretend machines, but this hasn't 
solved the problem.

Thanks in advance.

Bryan
