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.

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. Nesser II & Bergstrom Informational [Page 2]
RFC 3793 IPv4 Addresses in the IETF Sub-IP Area May 2004 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 presented to the Internet community. Sometimes flaws are exposed or they are one of many competing solutions to problems. In these later cases, no discussion is presented as it would not serve the purpose of this discussion. 5.01. RFC 3031 Multiprotocol Label Switching Architecture (MPLS) There are no IPv4 dependencies in this specification. 5.02. RFC 3032 MPLS Label Stack Encoding This specification is both IPv4 and IPv6 aware and needs no changes. 5.03. RFC 3034 Use of Label Switching on Frame Relay Networks Specification There are no IPv4 dependencies in this specification. 5.04. RFC 3035 MPLS using LDP and ATM VC Switching There are no IPv4 dependencies in this specification. 5.05. RFC 3036 LDP Specification This specification is both IPv4 and IPv6 aware and needs no changes. 5.06. RFC 3038 VCID Notification over ATM link for LDP There are no IPv4 dependencies in this specification. 6. Experimental RFCs Experimental RFCs typically define protocols that do not have widescale implementation or usage on the Internet. They are often propriety in nature or used in limited arenas. They are documented to the Internet community in order to allow potential interoperability or some other potential useful scenario. In a few cases they are presented as alternatives to the mainstream solution to an acknowledged problem. Nesser II & Bergstrom Informational [Page 3]
RFC 3793 IPv4 Addresses in the IETF Sub-IP Area May 2004 6.01. RFC 3063 MPLS Loop Prevention Mechanism There are no IPv4 dependencies in this specification. 7. Summary of Results In the initial survey of RFCs 0 positives were identified out of a total of 7, broken down as follows: Standards: 0 out of 0 or 0.00% Draft Standards: 0 out of 0 or 0.00% Proposed Standards: 0 out of 6 or 0.00% Experimental RFCs: 0 out of 1 or 0.00% Of those identified many require no action because they document outdated and unused protocols, while others are document protocols that are actively being updated by the appropriate working groups. Additionally there are many instances of standards that should be updated but do not cause any operational impact if they are not updated. The remaining instances are documented below. 7.01. Standards There are no standards within the scope of this document. 7.02. Draft Standards There are no draft standards within the scope of this document. 7.03. Proposed Standards There are no proposed standards with recommendations in this document. 7.04. Experimental RFCs There are no experimental standards with recommendations in this document. 8. Security Considerations This memo examines the IPv6-readiness of specifications; this does not have security considerations in itself. 9.
