Abstract
DHCP provides a superset of the functions provided by BOOTP. This
document describes the interactions between DHCP and BOOTP network
participants.
1. Introduction
The Dynamic Host Configuration Protocol (DHCP) provides a mechanism
for transmitting configuration parameters to hosts using the TCP/IP
protocol suite. The format of DHCP messages is based on the format
of BOOTP messages, so that, in certain circumstances, DHCP and BOOTP
participants may exchange messages. This document specifies the ways
in which DHCP and BOOTP participants may interoperate.
DHCP introduces a small change in terminology intended to clarify the
meaning of one of the fields. What was the "vendor extensions" field
in BOOTP has been re-named the "options" field in DHCP. Similarly,
the tagged data items that were used inside the BOOTP "vendor
extensions" field, which were formerly referred to as "vendor
extensions", are now termed simply "options". This document will
refer to BOOTP vendor extensions and DHCP options uniformly as
"options".
Throughout this document, DHCP messages that include a 'DHCP message
type' option will be referred to by the type of the message; e.g., a
DHCP message with 'DHCP message type' option type 1 will be referred
to as a "DHCPDISCOVER" message.
