Gont Category: Standards Track UTN-FRH / SI6 Networks ISSN: 2070-1721 November 2012 Formally Deprecating Some IPv4 Options Abstract A number of IPv4 options have become obsolete in practice, but have never been formally deprecated. This document deprecates such IPv4 options, thus cleaning up the corresponding IANA registry. Additionally, it obsoletes RFCs 1385, 1393, 1475, and 1770, and requests that the RFC Editor change their status to Historic. Status of This Memo This is an Internet Standards Track document.

Introduction The Internet Protocol version 4 (IPv4) [RFC791] provides for expansion of the protocol by supporting a number of "options" in the variable-length IPv4 header. IPv4 options are identified by an option "type" value, whose registration is managed by IANA [IANA-IP]. A number of IPv4 options have become obsolete in practice, but have never been formally deprecated. This document deprecates such IPv4 options, thus cleaning up the corresponding IANA registry. This document also obsoletes [RFC1385], [RFC1393], [RFC1475], and [RFC1770], and requests that the RFC Editor change their status to Historic. 2. Discussion of Deprecated Options The following subsections discuss the options being deprecated. No other reference information has been found. 2.1. Stream ID The Stream ID option is obsolete. It is specified in RFC 791 [RFC791], and is deprecated in Section 3.2.1.8 of RFC 1122 [RFC1122] and Section 4.2.2.1 of RFC 1812 [RFC1812]. Pignataro & Gont Standards Track [Page 2] RFC 6814 Deprecating Some IPv4 Options November 2012 2.2. Extended Internet Protocol The Extended Internet Protocol option is defined in [RFC1385] and is superseded by [RFC2460]. 2.3. Traceroute The Traceroute option is defined in [RFC1393]. The Traceroute option is defined as Experimental; it was never widely deployed on theShow full document text
