                 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.

1.  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   The Stream ID option is obsolete.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].
