Abstract
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.
1. Introduction
The Dynamic Host Configuration Protocol (DHCP) [1] provides a
framework for passing configuration information to hosts on a 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" [2].
