Abstract

   This document seeks to document all usage of IPv4 addresses in
   currently deployed IETF Sub-IP Area documented standards.  In order
   to successfully transition from an all IPv4 Internet to an all IPv6
   Internet, many interim steps will be taken.  One of these steps is
   the evolution of current protocols that have IPv4 dependencies.  It
   is hoped that these protocols (and their implementations) will be
   redesigned to be network address independent, but failing that will
   at least dually support IPv4 and IPv6.  To this end, all Standards
   (Full, Draft, and Proposed) as well as Experimental RFCs will be
   surveyed and any dependencies will be documented.

1.  Introduction

   This document is part of a document set aiming to document all usage
   of IPv4 addresses in IETF standards.  In an effort to have the
   information in a manageable form, it has been broken into 7 documents
   conforming to the current IETF areas (Application,  Internet,
   Operations & Management, Routing, Security, Sub-IP and Transport).

   For a full introduction, please see the introduction [1].

2.  Document Organization

   The rest of the document sections are described below.

   Sections 3, 4, 5, and 6 each describe the raw analysis of Full,
   Draft, and Proposed Standards, and Experimental RFCs.  Each RFC is
   discussed in its turn starting with RFC 1 and ending with (around)
   RFC 3100. The comments for each RFC are "raw" in nature.  That is,
   each RFC is discussed in a vacuum and problems or issues discussed do
   not "look ahead" to see if the problems have already been fixed.

   Section 7 is an analysis of the data presented in Sections 3, 4, 5,
   and 6.  It is here that all of the results are considered as a whole
   and the problems that have been resolved in later RFCs are
   correlated.

3.  Full Standards

   Full Internet Standards (most commonly simply referred to as
   "Standards") are fully mature protocol specification that are widely
   implemented and used throughout the Internet.

   There are no full standards within the scope of this document.

4.  Draft Standards

   Draft Standards represent the penultimate standard level in the IETF.
   A protocol can only achieve draft standard when there are multiple,
   independent, interoperable implementations.  Draft Standards are
   usually quite mature and widely used.

   There are no draft standards within the scope of this document.

5.  Proposed Standards

   Proposed Standards are introductory level documents.  There are no
   requirements for even a single implementation.  In many cases
   Proposed are never implemented or advanced in the IETF standards
   process.  They therefore are often just proposed ideas that are
