             Formally Obsoleting some Historic IPv4 Options
             draft-gp-intarea-obsolete-ipv4-options-iana-00

Abstract

   A number of IPv4 options have become obsolete in practice, but have
   never been formally obsoleted.  This document obsoletes such IPv4
   options, thus cleaning up the corresponding IANA registry, and
   serving as a basis for providing advice about the filtering of
   packets containing these options.

Internet-Draft           Obsoleting IPv4 Options           February 2012

1.  Introduction

   The Internet Protocol version 4 (IPv4) [RFC0791] 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 obsoleted.  This document obsoletes such IPv4
   options, "cleaning up" the corresponding IANA registry.

2.  Discussion of Obsoleted Options

2.1.  Stream ID

   The Stream ID option is obsolete.  It is specified in RFC 791
   [RFC0791], and obsoleted in Section 3.2.1.8 of RFC 1122 [RFC1122] and
   Section 4.2.2.1 of RFC 1812 [RFC1812].

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   superseded by [RFC2460].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
