One further suggestion, take a look at www.netreg.org, or
www.net.cmu.edu/netreg

That might make it easier / harder on you depending on what your trying to
do.

Bear in mind that you CANNOT prevent someone using your network with 
this. They can either spoof their MAC address, or they can manually 
code their IP address.

It depends on what you want to do. If your ONLY concern is to give IP 
addresses only to MAC addresses which you know about, then you can 
put "deny unknown clients ;" in your global scope, and list each 
device in a host statement :

host host1 { hardware ethernet xx:xx:xx:xx:xx:xx ; } ;

If you want anything else then I suggest you read man dhcpd.conf and 
look at the section on subclassing. You can then do different things 
based on what class (or classes) a device is a member of.
