Network Working Group C. Mickles, Ed. Request for Comments: 3790 Category: Informational P. Nesser, II Nesser & Nesser Consulting June 2004 Survey of IPv4 Addresses in Currently Deployed IETF Internet Area Standards Track and Experimental Documents Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2004).Abstract
This document seeks to document all usage of IPv4 addresses in currently deployed IETF Internet 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.Table of Contents

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, Management & Operations, Routing, Security, Sub-IP and Transport). This specific document focuses on usage of IPv4 addresses within the Internet area. For a full introduction, please see the introduction [1] document.2. Document Organization
The following 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 turn starting with RFC 1 and ending in (about) 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 any of the issues raised 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.3.1. RFC 791 Internet Protocol
This specification defines IPv4; IPv6 has been specified in separate documents.3.2. RFC 792 Internet Control Message Protocol
This specification defines ICMP, and is inherently IPv4 dependent.3.3. RFC 826 Ethernet Address Resolution Protocol
There are no IPv4 dependencies in this specification.
3.4. RFC 891 DCN Local-Network Protocols
There are many implicit assumptions about the use of IPv4 addresses in this document.3.5. RFC 894 Standard for the transmission of IP datagrams over Ethernet networks
This specification specifically deals with the transmission of IPv4 packets over Ethernet.3.6. RFC 895 Standard for the transmission of IP datagrams over experimental Ethernet networks
This specification specifically deals with the transmission of IPv4 packets over experimental Ethernet.3.7. RFC 903 Reverse Address Resolution Protocol
There are no IPv4 dependencies in this specification.3.8. RFC 919 Broadcasting Internet Datagrams
This specification defines broadcasting for IPv4; IPv6 uses multicast so this is not applicable.3.9. RFC 922 Broadcasting Internet datagrams in the presence of subnets
This specification defines how broadcasts should be treated in the presence of subnets. IPv6 uses multicast so this is not applicable.3.10. RFC 950 Internet Standard Subnetting Procedure
This specification defines IPv4 subnetting; similar functionality is part of IPv6 addressing architecture to begin with.3.11. RFC 1034 Domain Names: Concepts and Facilities
In Section 3.6, "Resource Records", the definition of A record is: RDATA which is the type and sometimes class dependent data which describes the resource: A For the IN class, a 32 bit IP address
And Section 5.2.1, "Typical functions" defines: 1. Host name to host address translation. This function is often defined to mimic a previous HOSTS.TXT based function. Given a character string, the caller wants one or more 32 bit IP addresses. Under the DNS, it translates into a request for type A RRs. Since the DNS does not preserve the order of RRs, this function may choose to sort the returned addresses or select the "best" address if the service returns only one choice to the client. Note that a multiple address return is recommended, but a single address may be the only way to emulate prior HOSTS.TXT services. 2. Host address to host name translation This function will often follow the form of previous functions. Given a 32 bit IP address, the caller wants a character string. The octets of the IP address are reversed, used as name components, and suffixed with "IN-ADDR.ARPA". A type PTR query is used to get the RR with the primary name of the host. For example, a request for the host name corresponding to IP address 1.2.3.4 looks for PTR RRs for domain name "4.3.2.1.IN-ADDR.ARPA". There are, of course, numerous examples of IPv4 addresses scattered throughout the document.3.12. RFC 1035 Domain Names: Implementation and Specification
Section 3.4.1, "A RDATA format", defines the format for A records: +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | ADDRESS | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ where: ADDRESS A 32 bit Internet address. Hosts that have multiple Internet addresses will have multiple A records. A records cause no additional section processing. The RDATA section of an A line in a master file is an Internet address expressed as four decimal numbers separated by dots without any embedded spaces (e.g.,"10.2.0.52" or "192.0.5.6").
And Section 3.4.2, "WKS RDATA", format is: +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | ADDRESS | +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ | PROTOCOL | | +--+--+--+--+--+--+--+--+ | | | / <BIT MAP> / / / +--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+--+ where: ADDRESS An 32 bit Internet address PROTOCOL An 8 bit IP protocol number <BIT MAP> A variable length bit map. The bit map must be a multiple of 8 bits long. The WKS record is used to describe the well known services supported by a particular protocol on a particular internet address. The PROTOCOL field specifies an IP protocol number, and the bit map has one bit per port of the specified protocol. The first bit corresponds to port 0, the second to port 1, etc. If the bit map does not include a bit for a protocol of interest, that bit is assumed zero. The appropriate values and mnemonics for ports and protocols are specified in RFC1010. For example, if PROTOCOL=TCP (6), the 26th bit corresponds to TCP port 25 (SMTP). If this bit is set, a SMTP server should be listening on TCP port 25; if zero, SMTP service is not supported on the specified address. The purpose of WKS RRs is to provide availability information for servers for TCP and UDP. If a server supports both TCP and UDP, or has multiple Internet addresses, then multiple WKS RRs are used. WKS RRs cause no additional section processing. Section 3.5, "IN-ADDR.ARPA domain", describes reverse DNS lookups and is clearly IPv4 dependent. There are, of course, numerous examples of IPv4 addresses scattered throughout the document.
3.13. RFC 1042 Standard for the transmission of IP datagrams over IEEE 802 networks
This specification specifically deals with the transmission of IPv4 packets over IEEE 802 networks.3.14. RFC 1044 Internet Protocol on Network System's HYPERchannel: Protocol Specification
There are a variety of methods used in this standard to map IPv4 addresses to 32 bits fields in the HYPERchannel headers. This specification does not support IPv6.3.15. RFC 1055 Nonstandard for transmission of IP datagrams over serial lines: SLIP
This specification is more of an analysis of the shortcomings of SLIP which is unsurprising. The introduction of PPP as a general replacement of SLIP has made this specification essentially unused. No update need be considered.3.16. RFC 1088 Standard for the transmission of IP datagrams over NetBIOS networks
This specification documents a technique to encapsulate IP packets inside NetBIOS packets. The technique presented of using NetBIOS names of the form IP.XX.XX.XX.XX will not work for IPv6 addresses since the length of IPv6 addresses will not fit within the NetBIOS 15 octet name limitation.3.17. RFC 1112 Host Extensions for IP Multicasting
This specification defines IP multicast. Parts of the document are IPv4 dependent.3.18. RFC 1132 Standard for the transmission of 802.2 packets over IPX networks
There are no IPv4 dependencies in this specification.3.19. RFC 1201 Transmitting IP traffic over ARCNET networks
The major concerns of this specification with respect to IPv4 addresses occur in the resolution of ARCnet 8bit addresses to IPv4 addresses in an "ARPlike" method. This is incompatible with IPv6.
3.20. RFC 1209 The Transmission of IP Datagrams over the SMDS Service
This specification defines running IPv4 and ARP over SMDS. The methods described could easily be extended to support IPv6 packets.3.21. RFC 1390 Transmission of IP and ARP over FDDI Networks
This specification defines the use of IPv4 address on FDDI networks. There are numerous IPv4 dependencies in the specification. In particular the value of the Protocol Type Code (2048 for IPv4) and a corresponding Protocol Address length (4 bytes for IPv4) needs to be created. A discussion of broadcast and multicast addressing techniques is also included, and similarly must be updated for IPv6 networks. The defined MTU limitation of 4096 octets of data (with 256 octets reserved header space) should remain sufficient for IPv6.3.22. RFC 1661 The Point-to-Point Protocol (PPP)
There are no IPv4 dependencies in this specification.3.23. RFC 1662 PPP in HDLC-like Framing
There are no IPv4 dependencies in this specification.3.24. RFC 2427 Multiprotocol Interconnect over Frame Relay
There are no IPv4 dependencies in this specification.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.4.1. RFC 951 Bootstrap Protocol (BOOTP)
This protocol is designed specifically for use with IPv4, for example: Section 3. Packet Format All numbers shown are decimal, unless indicated otherwise. The BOOTP packet is enclosed in a standard IP UDP datagram. For simplicity it is assumed that the BOOTP packet is never fragmented. Any numeric fields shown are packed in 'standard network byte order', i.e., high order bits are sent first.
In the IP header of a bootrequest, the client fills in its own IP source address if known, otherwise zero. When the server address is unknown, the IP destination address will be the 'broadcast address' 255.255.255.255. This address means 'broadcast on the local cable, (I don't know my net number)'. FIELD BYTES DESCRIPTION ----- ----- --- [...] ciaddr 4 client IP address; filled in by client in bootrequest if known. yiaddr 4 'your' (client) IP address; filled by server if client doesn't know its own address (ciaddr was 0). siaddr 4 server IP address; returned in bootreply by server. giaddr 4 gateway IP address, used in optional cross-gateway booting. Since the packet format is a fixed 300 bytes in length, an updated version of the specification could easily accommodate an additional 48 bytes (4 IPv6 fields of 16 bytes to replace the existing 4 IPv4 fields of 4 bytes).4.2. RFC 1188 Proposed Standard for the Transmission of IP Datagrams over FDDI Networks
This document is clearly informally superseded by RFC 1390, "Transmission of IP and ARP over FDDI Networks", even though no formal deprecation has been done. Therefore, this specification is not considered further in this memo.4.3. RFC 1191 Path MTU discovery
The entire process of PMTU discovery is predicated on the use of the DF bit in the IPv4 header, an ICMP message (also IPv4 dependent) and TCP MSS option. This is not compatible with IPv6.4.4. RFC 1356 Multiprotocol Interconnect on X.25 and ISDN
Section 3.2 defines an NLPID for IP as follows: The value hex CC (binary 11001100, decimal 204) is IP. Conformance with this specification requires that IP be supported.
See section 5.1 for a diagram of the packet formats. Clearly a new NLPID would need to be defined for IPv6 packets.4.5. RFC 1534 Interoperation Between DHCP and BOOTP
There are no IPv4 dependencies in this specification.4.6. RFC 1542 Clarifications and Extensions for the Bootstrap Protocol
There are no new issues other than those presented in Section 4.1.4.7. RFC 1629 Guidelines for OSI NSAP Allocation in the Internet
There are no IPv4 dependencies in this specification.4.8. RFC 1762 The PPP DECnet Phase IV Control Protocol (DNCP)
There are no IPv4 dependencies in this specification.4.9. RFC 1989 PPP Link Quality Monitoring
There are no IPv4 dependencies in this specification.4.10. RFC 1990 The PPP Multilink Protocol (MP)
Section 5.1.3, "Endpoint Discriminator Option", defines a Class header field: Class The Class field is one octet and indicates the identifier address space. The most up-to-date values of the LCP Endpoint Discriminator Class field are specified in the most recent "Assigned Numbers" RFC. Current values are assigned as follows: 0 Null Class 1 Locally Assigned Address 2 Internet Protocol (IP) Address 3 IEEE 802.1 Globally Assigned MAC Address 4 PPP Magic-Number Block 5 Public Switched Network Directory Number A new class field needs to be defined by the IANA for IPv6 addresses.
4.11. RFC 1994 PPP Challenge Handshake Authentication Protocol (CHAP)
There are no IPv4 dependencies in this specification.4.12. RFC 2067 IP over HIPPI
Section 5.1, "Packet Formats", contains the following excerpt: EtherType (16 bits) SHALL be set as defined in Assigned Numbers: IP = 2048 ('0800'h), ARP = 2054 ('0806'h), RARP = 32,821 ('8035'h). Section 5.5, "MTU", has the following definition: The MTU for HIPPI-SC LANs is 65280 bytes. This value was selected because it allows the IP packet to fit in one 64K byte buffer with up to 256 bytes of overhead. The overhead is 40 bytes at the present time; there are 216 bytes of room for expansion. HIPPI-FP Header 8 bytes HIPPI-LE Header 24 bytes IEEE 802.2 LLC/SNAP Headers 8 bytes Maximum IP packet size (MTU) 65280 bytes ------------ Total 65320 bytes (64K - 216) This definition is not applicable for IPv6 packets since packets can be larger than the IPv4 limitation of 65280 bytes.4.13. RFC 2131 Dynamic Host Configuration Protocol
This version of DHCP is highly predicated of IPv4. It is not compatible with IPv6.4.14. RFC 2132 DHCP Options and BOOTP Vendor Extensions
This is an extension to an IPv4-only specification.4.15. RFC 2390 Inverse Address Resolution Protocol
There are no IPv4 dependencies in this specification.4.16. RFC 2460 Internet Protocol, Version 6 (IPv6) Specification
This document defines IPv6 and has no IPv4 issues.
