Abstract

   This investigation work seeks to document all usage of IPv4 addresses
   in currently deployed IETF Routing 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 work aims to document all usage of IPv4 addresses in currently
   deployed IETF Routing Area documented standards.  Also, throughout
   this document there are discussions on how routing protocols might be
   updated to support IPv6 addresses.

   This material was originally presented within a single document, but
   in an effort to have the information in a manageable form, it has
   subsequently been split into 7 documents conforming to the current
   IETF main areas (Application [2], Internet [3], Operations &
   Management [4], Routing [this document], Security [5], Sub-IP [6] and
   Transport [7]).

   The general overview, methodology used during documentation and scope
   of the investigation for the whole 7 documents can be found in the
   introduction of this set of documents [1].

   It is important to mention that to perform this study the following
   classes of IETF standards are investigated: Full, Draft, and
   Proposed, as well as Experimental.  Informational, BCP and Historic
   RFCs are not addressed.  RFCs that have been obsoleted by either
   newer versions or as they have transitioned through the standards
   process are also not covered.

2.  Document Organization

   The main Sections of this document are described below.

   Sections 3, 4, 5, and 6 each describe the raw analysis of Full,
   Draft, Proposed Standards and Experimental RFCs.  Each RFC is
   discussed in its turn starting with RFC 1 and ending (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.
