I have a 2860 working as a DHCP server.

I have several devices where I am using the IP binding to allocate DHCP addresses. There are many other devices which I want to have addresses served so I can't use "strict bind"

I want to prevent devices from "grabbing" IP addresses in the subnet of the DHCP server: ie they either get served an address or they have one served through strict bind. But those are the only options. Is there a way I can enforce that?
