The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing configuration information to hosts on a Transmission Control Protocol/Internet Protocol (TCP/IP) network. Configuration parameters and other control information are carried in tagged data items that are stored in the 'options' field of the DHCP message. The data items themselves are also called "options".
DHCP protocol messages are identified by the 'DHCP Message Type' option (option code 51). Each message type is defined by the data value carried in the 'DHCP Message Type' option.
New DHCP options and message types may be defined after the publication of the DHCP specification to accommodate requirements for conveyance of new configuration parameters or to accommodate new protocol semantics. This document describes the procedure for defining new DHCP options and message types.
