Network Working Group R. Droms Request for Comments: 3679 Cisco Systems Category: Informational January 2004 Unused Dynamic Host Configuration Protocol (DHCP) Option Codes Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2004). All Rights Reserved. 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. Droms Informational [Page 1] RFC 3679 Unused DHCP Option Codes January 2004 2.1.
