Abstract

Prior to the publication of RFC 2489 (which was updated by RFC 2939), several option codes were assigned to proposed Dynamic Host Configuration Protocol (DHCP) options that were subsequently never used. This document lists those unused option codes and directs IANA to make these option codes available for assignment to other DHCP options in the future.

Abstract

Prior to the publication of RFC 2489 (which was updated by RFC 2939),

several option codes were assigned to proposed Dynamic Host

Configuration Protocol (DHCP) options that were subsequently never

used. This document lists those unused option codes and directs IANA

to make these option codes available for assignment to other DHCP

options in the future.

The document also lists several option codes that are not currently

documented in an RFC but should not be made available for

reassignment to future DHCP options.

1. Introduction

Section 2 of this document lists the unused DHCP option codes from

the IANA list of BOOTP and DHCP option codes [1]. Each option code

includes any known documentation and contact information from the

IANA list. IANA will make these option codes available for

assignment to other DHCP options in the future.

Section 3 lists several DHCP option codes that are not currently

documented in an RFC but should not be made available for

reassignment to future DHCP options.

2. Unused DHCP Option Codes to be Reassigned to Future DHCP Options

The option codes listed in this section are to be returned to IANA

for reassignment to new options. Responses from associated contact

persons are noted where they have been received.
