I want to setup a DHCP server/scope that hands out permanent IPs to
specified hosts only to approx 200 systems.
I'm assuming I would setup a scope ip range and then just set individual
"reservations" using each of the systems MAC addresses. This is understood
but since the IP range will be larger then whats needed how can I prevent
foreign systems from getting an available IP since its MAC address is not
within the reservation list?

Should I use an "exception range", specifying the entire Address Pool?

All the help would be greatly appreciated.
 
You got to create a scope that contains only 200 differents IP. Create a
reservation for each of you client in this scope.
The lease duration is not really an issue if you proceed this way. It is not
really good to configure really long lease duration if for example you need
to change the gateway or dns servers, or any other conf option assigned by
the DHCP.

And finally, this will not be any kind of strong security trick. It will
remain possible for anybody to configure manually his network card to get one
of your scope IP.
