Network Working Group R. Droms Internet-Draft Cisco Systems Expires: August 20, 2003 February 19, 2003 Unused DHCP Option Codes draft-ietf-dhc-unused-optioncodes-00 Status of this Memo This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." The list of current Internet-Drafts can be accessed at http://www.ietf.org/ietf/1id-abstracts.txt. The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html. This Internet-Draft will expire on August 20, 2003. Copyright Notice Copyright (C) The Internet Society (2003). All Rights Reserved. Abstract Prior to the publication of RFC2939 (which was updated by RFC2489), several option codes were assigned to proposed DHCP options that were subsequently never used. This document lists those unused option codes and will be used to confirm that these option codes can be reused for other DHCP options in the future. 1. Introduction 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. Droms Expires August 20, 2003 [Page 1] Internet-Draft Unused DHCP Option Codes February 2003 2.
