That's easy enough to do based on MAC address.  With some DHCP servers
you can create a list of MACs to allow or deny.


but you don't need to ask the dhcp to give an address :-)

only a firewall or proxy can filter out IP's (I think)


You can also configure a DHCP server to assign a specific IP to a MAC. 
If only allowing specific MAC addresses an IP address, you have a fairly
effective filter.  Also, managed switches can be configured to allow
only specific MACs to connect or even limit the number of MACs connected
through a port.  There are many ways to set up security.
