You can usually arrange to restrict machine that connect to only those with

only known MAC addresse
The DHCP server is configured to only service known MAC addresses,
however this won't stop an unknown MAC from getting onto the network
with an available IP already configured. DHCP server won't know about
it and thus won't do anything about it. So to me, this is something
beyond what the DHCP server itself can do (or should do). That's what
I'm looking for, some way to block everything else that may pop up, that
did not use the DHCP server to get an IP to begin with.
