Dynamic Host Configuration Protocol (DHCP)

DHCP allows a DHCP server to dynamically assign IP addresses to any DHCP client that requests one. The DHCP server usually has a limited set of IP addresses, and assigns them on a first come first serve basis. When a DHCP client boots up, it will broadcast a DHCP request over TCP/IP. If a DHCP server is present, that server will respond to the DHCP client with an IP address, subnet mask and gateway. This response also includes a lease (or expiration) time for the IP address being assigned. If the DHCP client then wants to use this address, the client must acknowledge the server’s response, and then periodically renew the lease on that IP address. If the lease expires, the DHCP server is free to re-issue that IP address to another DHCP client.

Note	DHCP only manages dynamic allocation of IP addresses.
	Assigning device names with DHCP is not recommended.
