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.
