description
	DHCP (Dynamic Host Configuration Protocol) is a protocol which allows
	individual devices on an IP network to get their own network
	configuration information (IP address, subnetmask, broadcast address,
	etc.) from a DHCP server. The overall purpose of DHCP is to make it
	easier to administer a large network.
