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.
