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].
