Abstract -This document seeks to document all usage of IPv4 addresses in currently -deployed IETF Application 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. + The transition from an all IPv4 network to an all IPv6 network + requires several interim steps, being one of them the evolution of + current IPv4 dependent protocols to protocols that are independent + of the type of IP addresses used. Hence, it is hoped that protocols + will be redesigned and re-implemented to become network address + independent, or at least to dually support IPv4 and IPv6. + To achieve that step, it is necessary to survey and document all IPv4 + dependencies experienced by current standards - Full, Draft, and + Proposed - and Experimental RFCs. Hence, this document describes + IPv4 addressing dependencies that deployed IETF Application Area + documented Standards may experience. -1.0 Introduction +Contents -This work began as a megolithic document draft-ietf-ngtrans- -ipv4survey-XX.txt. In an effort to rework the information into a more -manageable form, it has been broken into 8 documents conforming to the -current IETF areas (Application, General, Internet, Manangement & Operations, -Routing, Security, Sub-IP and Transport). +1 Introduction 15 -1.1 Short Historical Perspective +2 Document Organization 15 -There are many challenges that face the Internet Engineering community. -The foremost of these challenges has been the scaling issue. How to grow -a network that was envisioned to handle thousands of hosts to one that -will handle tens of millions of networks with billions of hosts. Over the -years this scaling problem has been overcome with changes to the network -layer and to routing protocols.

In -early 1993 RFC 1466 was published directing assignment of blocks of Class -C's be given out instead of Class B's.

To do this the Internet has sacrificed the underlying -"End-to-End" principle. +9 Security Considerations 66 -In the early 1990's the IETF was aware of these potential problems and -began a long design process to create a successor to IPv4 that would -address these issues. The outcome of that process was IPv6. +1 Introduction -The purpose of this document is not to discuss the merits or problems of -IPv6. That is a debate that is still ongoing and will eventually be -decided on how well the IETF defines transition mechanisms and how -industry accepts the solution. The question is not "should," but "when." + The exhaustive documentation of IPv4 addresses usage in currently + deployed IETF documented standards has now been broken + into seven documents conforming to current IETF main areas - + Applications, Internet, Operations and Management, Routing, Sub- + IP, and Transport. A general overview of the documentation, as well + as followed methodology and historical perspective can be found in + [1]. + This document represents one of the seven blocks, and its scope + is limited to the use of IPv4 addresses in IETF Application Area + documented Standards. -1.2 A Brief Aside +2 Document Organization -Throughout this document there are discussions on how protocols might be -updated to support IPv6 addresses. Although current thinking is that IPv6 -should suffice as the dominant network layer protocol for the lifetime of -the author, it is not unreasonable to contemplate further upgrade to IP. -Work done by the IRTF Interplanetary Internet Working Group shows one idea -of far reaching thinking. It may be a reasonable idea (or may not) to -consider designing protocols in such a way that they can be either IP -version aware or independent. This idea must be balanced against issues -of simplicity and performance. Therefore it is recommended that protocol -designer keep this issue in mind in future designs. + The remainder sections are organized as follows. Sections 3, 4, 5, and + 6 describe, respectively, the raw analysis of Internet Standards [3]: + Full, Draft and Proposed Standards, and Experimental RFCs. For + each section, standards are analysed by their RFC sequential order, + i.e., from RFC 1 to RFC 3247. Also, the comments presented for + each RFC are raw in their nature, i.e., each RFC is simply analysed + in terms of possible IPv4 addressing dependencies. Finally, Section + 7 presents a global overview of the data described in the previous + sections, and suggests possible future steps. -Just as a reminder, remember the words of Jon Postel: +3 Full Standards - "Be conservative in what you send; be liberal in what - you accept from others." + Internet Full Standards attain the highest level of maturity on + the standards track process. They are commonly referred to as + "Standards", and represent fully technical mature specifications, + widely implemented and used throughout the Internet. -2.0 Methodology +3.1 RFC821, RFC1869: SMTP Service Extensions -To perform this study each class of IETF standards are investigated in -order of maturity: Full, Draft, and Proposed, as well as Experimental. -Informational RFC are not addressed. RFCs that have been obsoleted by -either newer versions or as they have transitioned through the standards -process are not covered. +3.1.1 RFC 821 -Please note that a side effect of this choice of methodology is that -some protocols that are defined by a series of RFC's that are of different -levels of standards maturity are covered in different spots in the -document. Likewise other natural groupings (i.e. MIBs, SMTP extensions, -IP over FOO, PPP, DNS, etc.) could easily be imagined. + Section 4.1.2 "Command Syntax" contains the following clear IPv4 + reference: -2.1 Scope + " ::= "." "." "." " -The procedure used in this investigation is an exhaustive reading of the -applicable RFC's. This task involves reading approximately 25000 pages -of protocol specifications. To compound this, it was more than a process -of simple reading. It was necessary to attempt to understand the purpose -and functionality of each protocol in order to make a proper determination -of IPv4 reliability. The author has made ever effort to make this effort -and the resulting document as complete as possible, but it is likely that -some subtle (or perhaps not so subtle) dependence was missed. The author -encourage those familiar (designers, implementers or anyone who has an -intimate knowledge) with any protocol to review the appropriate sections -and make comments. + Also, the following paragraph needs to be re-written, to eliminate + the explicit reference to a 32-bit ARPA Internet Address in four + 8-bit fields: -2.2 Document Organization + "Sometimes a host is not known to the translation function and + communication is blocked. To bypass this barrier two numeric forms + are also allowed for host 'names'. One form is a decimal integer + prefixed by a pound sign, "#", which indicates the number is the + address of the host. Another form is four small decimal integers + separated by dots and enclosed by brackets, e.g., "[123.255.37.2]". -The rest of the document sections are described below. +3.1.2 RFC 1869 -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 RFC 3247. The comments for -each RFC is "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. + There are no IPv4 dependencies in RFC 1869. -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. +3.2 RFC 822: Standard for the format of ARPA Internet + text messages -3.0 Full Standards + There are some IPv4 dependencies in RFC 822, which needs to be + re-written. Section 6.2.3. (Domain Terms) contains the following + text: -Full Internet Standards (most commonly simply referred to as "Standards") -are fully mature protocol specification that are widely implemented and -used throughout the Internet. + "A domain-ref must be THE official name of a registry, network, + or host. It is a symbolic reference, within a name sub-domain.
