[K12OSN] DHCP and specific IPs

Is there a way to make DHCP hand out IP addresses, but only to computers that we have the MAC addresses for? In other words, DHCP will hand out IP addresses, but only to a certain specified list of MAC addresses.

I am wanting to stop people from bringing unauthorized equipment from home and connecting it to our network and if it don't get an IP address, it won't work.

I already have the list of valid MAC addresses in the lease files for DHCP and I can weed out the ones that aren't ours.

The DHCP I am running is running on a linux server if that makes a difference.
