Can I secure my TCP/IP address allocation through DHCP?

I need to secure my TCP/IP address allocation through DHCP. I need to do this by Mac address so that only registered network cards can receive a DHCP address. I know I can do this through reservations but I have up to 10,000 Mac addresses that need to be inserted. I have all the Mac addresses in TXT format. Is there a bulk import of Mac addresses and reservation pool in any DHCP services you know of?

The only thing I know of offhand that will allow such a thing is the Cisco VLAN Management Policy Server for Cisco switches (see this link for a White Paper with details about this). Keep in mind that using MAC addresses isn't bulletproof; it's entirely possible to spoof a MAC address if the hardware and driver allow it to be changed. (Many do.)
