Dynamic Host Configuration Protocol

(protocol)
(DHCP) A protocol that provides a means to dynamically allocate IP addresses to computers on a local area network. The system administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address from the DHCP server. The request and grant process uses a lease concept with a controllable time period.

DHCP is defined in RFC 2131.

Microsoft introduced DHCP on their NT server with version 3.5 in late 1994.

DHCP

(Dynamic Host Configuration Protocol) The automatic assigning of IP addresses to client machines logging into an IP network. The same address, although technically temporary, may remain with a machine indefinitely unless a conflict arises with other devices on the network.

The DHCP software, which resides in the router or a server, eliminates the need to manually assign permanent "static" IP addresses to devices. In a home network, the DHCP function is built into the wireless router. See DHCPv6, IP network, private IP address, static IP address, IP address, DDNS, APIPA and link-local address.
