Abstract

This document seeks to record all usage of IPv4 addresses in currently deployed IETF Operations & Management Area accepted 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 set aiming to record 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].

Document Organization

The document is organized as 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.

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.

RFC 1155 Structure of Management Information

Section 3.2.3.2. IpAddress defines the following:

  This application-wide type represents a 32-bit internet address.
  It is represented as an OCTET STRING of length 4, in network
  byte-order.

There are several instances of the use of this definition in the rest of the document.

RFC 1212 Concise MIB definitions

In section 4.1.6 IpAddress is defined as:

  (6)  IpAddress-valued: 4 sub-identifiers, in the familiar
       a.b.c.d notation.

RFC 1213 Management Information Base

There are far too many instances of IPv4 addresses is this document to enumerate here. The particular object groups that are affected are the IP group, the ICMP group, the TCP group, the UDP group, and the EGP group.

RFC 2578 Structure of Management Information Version 2 (SMIv2)

Section 7.1.5 defines the IpAddress data type:

  The IpAddress type represents a 32-bit internet address.  It is
  represented as an OCTET STRING of length 4, in network byte-order.

  Note that the IpAddress type is a tagged type for historical
  reasons.  Network addresses should be represented using an
  invocation of the TEXTUAL-CONVENTION macro.

Note the deprecated status of this type; see RFC 3291 for details on the replacement TEXTUAL-CONVENTION definitions.

RFC 2579 Textual Conventions for SMIv2

There are no IPv4 dependencies in this specification.

RFC 2580 Conformance Statements for SMIv2

There are no IPv4 dependencies in this specification.

RFC 2819 Remote Network Monitoring Management Information Base

There are no IPv4 dependencies in this specification.

RFC 3411 An Architecture for Describing SNMP Management Frameworks

There are no IPv4 dependencies in this specification.

RFC 3412 Message Processing and Dispatching for the Simple Network

Management Protocol (SNMP)

There are no IPv4 dependencies in this specification.

3.10. RFC 3413 SNMP Applications

There are no IPv4 dependencies in this specification.

3.11. RFC 3414 User-based Security Model (USM) for version 3 of the

   Simple Network Management Protocol (SNMPv3)

There are no IPv4 dependencies in this specification.

3.12. RFC 3415 View-based Access Control Model (VACM) for the Simple

   Network Management Protocol (SNMP)

There are no IPv4 dependencies in this specification.

3.13. RFC 3416 Protocol Operations for Version 2 of the Simple Network

   Management Protocol (SNMP)

Section 4.2.2.1., Example of Table Traversal, and Section 4.2.3.1., Another Example of Table Traversal, both use objects from MIB2 whose data contains IPv4 addresses. Other than their use in these example sections, there are no IPv4 dependencies in this specification.

3.14. RFC 3417 Transport Mappings for Version 2 of the Simple Network

   Management Protocol (SNMP)

Section 2 Definitions contains the following definition:

  SnmpUDPAddress ::= TEXTUAL-CONVENTION
      DISPLAY-HINT "1d.1d.1d.1d/2d"
      STATUS       current
      DESCRIPTION
              "Represents a UDP address:

                  octets   contents        encoding
                  1-4     IP-address      network-byte order
                  5-6     UDP-port        network-byte order
              "
     SYNTAX       OCTET STRING (SIZE (6))

Section 8.1, Usage Example, also contains examples which uses IPv4 address, but it has no significance in the operation of the specification.

3.15. RFC 3418 Management Information Base for Version 2 of the Simple

   Network Management Protocol (SNMP)

There are no IPv4 dependencies in this specification.

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.

RFC 1493 Definitions of Managed Objects for Bridges

There are no IPv4 dependencies in this specification.

RFC 1559 DECnet Phase IV MIB Extensions

There are no IPv4 dependencies in this specification.

RFC 1657 Definitions of Managed Objects for the Fourth

  Version of the Border Gateway Protocol (BGP-4) using SMIv2

The MIB defined in this RFC deals with objects in a BGP4 based routing system and therefore contain many objects that are limited by the IpAddress 32-bit value defined in MIB2. Clearly the values of this MIB are limited to IPv4 addresses. No update is needed, although a new MIB should be defined for BGP4+ to allow management of IPv6 addresses and routes.

RFC 1658 Definitions of Managed Objects for Character Stream

  Devices using SMIv2

There are no IPv4 dependencies in this specification.

RFC 1659 Definitions of Managed Objects for RS-232-like Hardware

  Devices using SMIv2

There are no IPv4 dependencies in this specification.

RFC 1660 Definitions of Managed Objects for Parallel-printer-like

  Hardware Devices using SMIv2

There are no IPv4 dependencies in this specification.

RFC 1694 Definitions of Managed Objects for SMDS Interfaces using

  SMIv2

This MIB module definition defines the following subtree:

ipOverSMDS OBJECT IDENTIFIER ::= { smdsApplications 1 }

-- Although the objects in this group are read-only, at the -- agent's discretion they may be made read-write so that the -- management station, when appropriately authorized, may -- change the addressing information related to the -- configuration of a logical IP subnetwork implemented on -- top of SMDS.

-- This table is necessary to support RFC1209 (IP-over-SMDS) -- and gives information on the Group Addresses and ARP -- Addresses used in the Logical IP subnetwork. -- One SMDS address may be associated with multiple IP -- addresses. One SNI may be associated with multiple LISs.

ipOverSMDSTable OBJECT-TYPE

      ipOverSMDSAddress     IpAddress,
      ipOverSMDSHA          SMDSAddress,
      ipOverSMDSLISGA       SMDSAddress,
      ipOverSMDSARPReq      SMDSAddress
      }

ipOverSMDSIndex OBJECT-TYPE

   SYNTAX      IfIndex
   MAX-ACCESS  read-only
   STATUS      current
   DESCRIPTION
      "The value of this object identifies the
      interface for which this entry contains management
      information. "
   ::= { ipOverSMDSEntry 1 }

ipOverSMDSAddress OBJECT-TYPE

    SYNTAX      IpAddress
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
      "The IP address to which this entry's addressing
      information pertains."
   ::= { ipOverSMDSEntry 2 }

ipOverSMDSHA OBJECT-TYPE

   SYNTAX      SMDSAddress
   MAX-ACCESS  read-only

      "The SMDS address (individual or group) to which
      ARP Requests are to be sent."
   ::= { ipOverSMDSEntry 5 }

Although these object definitions are intended for IPv4 addresses, a similar MIB can be defined for IPv6 addressing.

RFC 1724 RIP Version 2 MIB Extension

As expected, this RFC is filled with IPv4 dependencies since it defines a MIB module for an IPv4-only routing protocol. A new MIB for RIPng is required.

RFC 1748 IEEE 802.5 MIB using SMIv2

There are no IPv4 dependencies in this specification.

4.10. RFC 1850 OSPF Version 2 Management Information Base

This MIB defines managed objects for OSPFv2 which is a protocol used to exchange IPv4 routing information. Since OSPFv2 is limited to IPv4 addresses, a new MIB is required to support a new version of OSPF that is IPv6 aware.

4.11. RFC 2115 Management Information Base for Frame Relay DTEs

   Using SMIv2

This specification has several examples of how IPv4 addresses might be mapped to Frame Relay DLCIs. Other than those examples there are no IPv4 dependencies in this specification.

4.12. RFC 2790 Host Resources MIB

There are no IPv4 dependencies in this specification.

4.13. RFC 2863 The Interfaces Group MIB

There are no IPv4 dependencies in this specification. There is some discussion in one object definition about an interface performing a self test, but the object itself is IP version independent.

4.14. RFC 3592 Definitions of Managed Objects for the Synchronous

   Optical Network/Synchronous Digital Hierarchy (SONET/SDH)

There are no IPv4 dependencies in this specification.

4.15. RFC 3593 Textual Conventions for MIB Modules Using Performance

   History Based on 15 Minute Intervals

There are no IPv4 dependencies in this specification.

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.

RFC 1239 Reassignment of experimental MIBs to standard MIBs

There are no IPv4 dependencies in this specification.

RFC 1269 Definitions of Managed Objects for the Border

  Gateway Protocol: Version 3

The use of BGP3 has been deprecated and is not discussed.

There are no IPv4 dependencies in this specification.

RFC 1382 SNMP MIB Extension for the X.25 Packet Layer

There are no IPv4 dependencies in this specification.

5.10. RFC 1461 SNMP MIB extension for Multiprotocol Interconnect

   over X.25

The following objects are defined in Section 4, Definitions:

mioxPleLastFailedEnAddr OBJECT-TYPE

       SYNTAX  OCTET STRING (SIZE(2..128))
       ACCESS  read-only
       STATUS  mandatory
       DESCRIPTION
               "The last Encapsulated address that failed
               to find a corresponding X.121 address and
               caused mioxPleEnAddrToX121LkupFlrs to be
               incremented.  The first octet of this object
               contains the encapsulation type, the
               remaining octets contain the address of that
               type that failed.  Thus for an IP address,
               the length will be five octets, the first
               octet will contain 204 (hex CC), and the
               last four octets will contain the IP

               address.  For a snap encapsulation, the
               first byte would be 128 (hex 80) and the
               rest of the octet string would have the snap
               header."
       ::= { mioxPleEntry 4 }

mioxPeerEnAddr OBJECT-TYPE

       SYNTAX    OCTET STRING (SIZE (0..128))
       ACCESS  read-write

       DESCRIPTION
               "The Encapsulation address of the remote
               host mapped by this table entry.  A length
               of zero indicates the remote IP address is
               unknown or unspecified for use as a PLE
               default.

               The first octet of this object contains the
               encapsulation type, the remaining octets
               contain an address of that type.  Thus for
               an IP address, the length will be five
               octets, the first octet will contain 204
               (hex CC), and the last four octets will
               contain the IP address.  For a snap
               encapsulation, the first byte would be 128
               (hex 80) and the rest of the octet string
               would have the snap header."
       DEFVAL { h }
       ::= { mioxPeerEntry 7 }

mioxPeerEncType OBJECT-TYPE

       SYNTAX  INTEGER (0..256)
       ACCESS  read-write
       STATUS  mandatory
       DESCRIPTION
               "The value of the encapsulation type.  For
               IP encapsulation this will have a value of
               204 (hex CC).  For SNAP encapsulated
               packets, this will have a value of 128 (hex
               80).  For CLNP, ISO 8473, this will have a
               value of 129 (hex 81).  For ES-ES, ISO 9542,
               this will have a value of 130 (hex 82).  A
               value of 197 (hex C5) identifies the Blacker
               X.25 encapsulation.  A value of 0,
               identifies the Null encapsulation.

               This value can only be written when the
               mioxPeerStatus object with the same

               mioxPeerIndex has a value of underCreation.
               Setting this object to a value of 256
               deletes the entry.  When deleting an entry,
               all other entries in the mioxPeerEncTable
               with the same mioxPeerIndex and with an
               mioxPeerEncIndex higher then the deleted

               values decremented by one."
       ::= { mioxPeerEncEntry 2 }

Updated values of the first byte of these objects can be defined to support IPv6 addresses.

All of the object definitions above (except trapDestProtocol) mention only IPv4 addresses. However, since they use a SYNTAX of OCTET STRING, they should work fine for IPv6 addresses. A new legitimate value of trapDestProtocol (i.e., SYNTAX addition of ipv6(3) should make this specification functional for IPv6.

5.32. RFC 2024 Definitions of Managed Objects for Data Link Switching

   using SMIv2

The following textual conventions are defined:

TAddress ::= TEXTUAL-CONVENTION

   STATUS  current
   DESCRIPTION
      "Denotes a transport service address.
       For dlswTCPDomain, a TAddress is 4 octets long,
       containing the IP-address in network-byte order."
   SYNTAX  OCTET STRING (SIZE (0..255))

-- DLSw over TCP dlswTCPDomain OBJECT IDENTIFIER ::= { dlswDomains 1 } -- for an IP address of length 4: -- -- octets contents encoding -- 1-4 IP-address network-byte order -- DlswTCPAddress ::= TEXTUAL-CONVENTION

           "Represents the IP address of a DLSw which uses
            TCP as a transport protocol."
   SYNTAX       OCTET STRING (SIZE (4))

Additionally there are many object definitions that use a SYNTAX of TAddress within the document. Interestingly the SYNTAX for TAddress is an OCTET string of up to 256 characters. It could easily accommodate a similar hybrid format for IPv6 addresses.

A new OID to enhance functionality for DlswTCPAddress could be added to support IPv6 addresses.

Clearly a subsequent revision of this MIB module should define equivalent IPv6 objects.

5.61. RFC 2561 Base Definitions of Managed Objects for TN3270E

The document states:

The MIB defined by this memo supports use of both IPv4 and IPv6 addressing.

This specification is both IPv4 and IPv6 aware.

5.62. RFC 2562 Definitions of Protocol and Managed Objects for

   SYNTAX       OCTET STRING (SIZE (0..255))

A new TC should be defined to handle IPv6 addresses.

5.64. RFC 2584 Definitions of Managed Objects for APPN/HPR in

   IP Networks

Many of the object definitions described in this document assume the use of the IPv4 only TOS header bits. It is therefore IPv4-only in nature and will not support IPv6.

There needs to be an update to allow an IPv6 based object for this value.

5.69. RFC 2619 RADIUS Authentication Server MIB

This MIB defines the followings objects:

This object needs to be deprecated and replaced by one that supports both IPv4 and IPv6 addresses.

5.70. RFC 2622 Routing Policy Specification Language (RPSL)

The only objects in the version of RPSL that deal with IP addresses are defined as:

<ipv4-address> An IPv4 address is represented as a sequence of four

  integers in the range from 0 to 255 separated by the character dot
  ".".  For example, 128.9.128.5 represents a valid IPv4 address.
  In the rest of this document, we may refer to IPv4 addresses as IP
  addresses.

<address-prefix> An address prefix is represented as an IPv4 address

  followed by the character slash "/" followed by an integer in the
  range from 0 to 32.  The following are valid address prefixes:
  128.9.128.5/32, 128.9.0.0/16, 0.0.0.0/0; and the following address
  prefixes are invalid:  0/0, 128.9/16 since 0 or 128.9 are not
  strings containing four integers.

There seems to be an awareness of IPv6 because of the terminology but it is not specifically defined. Therefore additional objects for IPv6 addresses and prefixes need to be defined.

5.71. RFC 2662 Definitions of Managed Objects for the ADSL Lines

There are no IPv4 dependencies in this specification.

5.72. RFC 2667 IP Tunnel MIB

The Abstract of this document says:

  This memo defines a Management Information Base (MIB) for use with
  network management protocols in the Internet community.  In
  particular, it describes managed objects used for managing tunnels
  of any type over IPv4 networks.  Extension MIBs may be designed
  for managing protocol-specific objects.  Likewise, extension MIBs
  may be designed for managing security-specific objects.  This MIB
  does not support tunnels over non-IPv4 networks (including IPv6
  networks).  Management of such tunnels may be supported by other
  MIBs.

A similar MIB for tunneling over IPv6 should be defined.

5.73. RFC 2669 DOCSIS Cable Device MIB Cable Device Management

   Information Base for DOCSIS compliant Cable Modems and
   Cable Modem Termination Systems

This document states:

  Please note that the DOCSIS 1.0 standard only requires Cable
  Modems to implement SNMPv1 and to process IPv4 customer traffic.
  Design choices in this MIB reflect those requirements.  Future
  versions of the DOCSIS standard are expected to require support
  for SNMPv3 and IPv6 as well.

5.74. RFC 2670 Radio Frequency (RF) Interface Management Information

   Base for MCNS/DOCSIS compliant RF interfaces

  This MIB defines the following objects:

5.82. RFC 2742 Definitions of Managed Objects for Extensible SNMP

   Agents

There are no IPv4 dependencies in this specification.

5.83. RFC 2748 The COPS (Common Open Policy Service) Protocol

5.86. RFC 2787 Definitions of Managed Objects for the Virtual

   Router Redundancy Protocol

As stated in the Overview section:

  Since the VRRP protocol is intended for use with IPv4 routers
  only, this MIB uses the SYNTAX for IP addresses which is specific
  to IPv4.  Thus, changes will be required for this MIB to
  interoperate in an IPv6 environment.

5.87. RFC 2788 Network Services Monitoring MIB

There are no IPv4 dependencies in this specification.

   Reference

This specification is both IPv4 and IPv6 aware and needs no changes.

5.93. RFC 2925 Definitions of Managed Objects for Remote

   Ping, Traceroute, and Lookup Operations

This MIB mostly is IPv4 and IPv6 aware. There are a few assumptions that are problems, though. In the following object definitions:

pingCtlDataSize OBJECT-TYPE

  SYNTAX      Unsigned32 (0..65507)
  UNITS       "octets"
  MAX-ACCESS  read-create

  STATUS      current
  DESCRIPTION
      "Specifies the size of the data portion to be
      transmitted in a ping operation in octets.  A ping
      request is usually an ICMP message encoded
      into an IP packet.  An IP packet has a maximum size
      of 65535 octets.  Subtracting the size of the ICMP
      or UDP header (both 8 octets) and the size of the IP
      header (20 octets) yields a maximum size of 65507
      octets."
  DEFVAL { 0 }
  ::= { pingCtlEntry 5 }

traceRouteCtlDataSize OBJECT-TYPE

  SYNTAX      Unsigned32 (0..65507)
  UNITS       "octets"
  MAX-ACCESS  read-create
  STATUS      current
  DESCRIPTION
      "Specifies the size of the data portion of a traceroute
      request in octets.  A traceroute request is essentially
      transmitted by encoding a UDP datagram into a
      IP packet.  So subtracting the size of a UDP header
      (8 octets) and the size of a IP header (20 octets)
      yields a maximum of 65507 octets."
  DEFVAL { 0 }
  ::= { traceRouteCtlEntry 6 }

The DESCRIPTION clauses need to be updated to remove the IPv4 dependencies.

5.94. RFC 2932 IPv4 Multicast Routing MIB

This specification is only defined for IPv4 and a similar MIB must be defined for IPv6.

5.95. RFC 2933 Internet Group Management Protocol MIB

As stated in this document:

  Since IGMP is specific to IPv4, this MIB does not support
  management of equivalent functionality for other address families,
  such as IPv6.

5.96. RFC 2940 Definitions of Managed Objects for Common

   Open Policy Service (COPS) Protocol Clients

This MIB is both IPv4 and IPv6 aware and needs no changes.

    Architecture

There are no IPv4 dependencies in this specification.

5.106. RFC 3060 Policy Core Information Model -- Version 1

    Specification (CIM)

There are no IPv4 dependencies in this specification.

5.107. RFC 3084 COPS Usage for Policy Provisioning (COPS-PR)

This specification builds on RFC 2748, and is both IPv4 and IPv6 capable. The specification defines a sample filter in section 4.3, which has "ipv4" in it.

5.108. RFC 3165 Definitions of Managed Objects for the Delegation of

    Management Scripts

There are no IPv4 dependencies in this specification.

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.

Summary of Results

In the initial survey of RFCs, 36 positives were identified out of a total of 153, broken down as follows:

     Standards:                         6 out of  15 or 40.00%
     Draft Standards:                   4 out of  15 or 26.67%
     Proposed Standards:               26 out of 112 or 23.21%
     Experimental RFCs:                 0 out of  11 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.

Standards

STD 16, Structure of Management Information (RFCs 1155 and 1212)

RFC 1155 and RFC 1212 (along with the informational document RFC 1215) define SMIv1. These documents have been superseded by RFCs 2578, 2579, and 2580 which define SMIv2. Since SMIv1 is no longer being used as the basis for new IETF MIB modules, the limitations identified in this Internet Standard do not require any action.

STD 17 Simple Network Management Protocol (RFC 1213)

The limitations identified have been addressed, because RFC 1213 has been split into multiple modules which are all IPv6 capable.

Draft Standards

BGP4 MIB (RFC 1657)

This problem is currently being addressed by the Inter Domain Routing (IDR) WG [2].

SMDS MIB (RFC 1694)

See Internet Area standards. Once a specification for IPv6 over SMDS is created a new MIB must be defined.

RIPv2 MIB (RFC 1724)

There is no updated MIB module to cover the problems outlined. A new MIB module should be defined.

OSPFv2 MIB (RFC 1850)

This problem is currently being addressed by the OSPF WG [3].

Transport MIB (RFC 1906)

RFC 1906 has been obsoleted by RFC 3417, Transport Mappings for SNMP, and the limitations of this specification have been addressed by that RFC, which defines TCs that can be used to specify transport domains in an IP version-independent way. RFC 3419 recommends that those TCs be used in place of SnmpUDPAddress when IPv6 support is required and for all new applications that are not SNMP-specific.

Proposed Standards

MIB for Multiprotocol Interconnect over X.25 (RFC 1461)

This problem has not been addressed. If a user requirement for IPv6 over X.25 develops (which is thought to be unlikely) then this MIB module will need to be updated in order to accommodate it.

PPP IPCP MIB (RFC 1473)

There is no updated MIB to cover the problems outlined. A new MIB should be defined.

Appletalk MIB (RFC 1742)

This problem has not been addressed. If a user requirement for IPv6 over Appletalk develops (which is thought to be unlikely) then this MIB module will need to be updated (or a new MIB module will need to be created) in order to accommodate it.

The Definitions of Managed Objects for IP Mobility

    Support using SMIv2 (RFC 2006)

The problems are being resolved by the MIP6 WG [4].

SMIv2 IP MIB (RFC 2011)

This issue is being resolved by the IPv6 WG [5].

SNMPv2 TCP MIB (RFC 2012)

This issue is being resolved by the IPv6 WG [6].

SNMPv2 UDP MIB (RFC 2013)

This issue is being resolved by the IPv6 WG [7].

RMON-II MIB (RFC 2021)

This issue has been brought to the attention of the RMONMIB WG. Currently, there is a work in progress [8] to update RFC 2021, but it does not address the problems that have been identified; it is expected that there will be a resolution in a future version of that document.

DataLink Switching using SMIv2 MIB (RFC 2024)

The problems have not been addressed and an updated MIB should be defined.

7.3.10. IP Forwarding Table MIB (RFC 2096)

This issue is being worked on by the IPv6 WG [9].

7.3.11. Classical IP & ARP over ATM MIB (RFC 2320)

The current version of Classical IP and ARP over ATM (RFC 2225) does not support IPv6. If and when that protocol specification is updated to add IPv6 support, then new MIB objects to represent IPv6 addresses will need to be added to this MIB module.

7.3.12. Multicast over UNI 3.0/3.1 ATM MIB (RFC 2417)

The current version of Multicast over UNI 3.0/3.1 ATM (RFC 2022) does not support IPv6. If and when that protocol specification is updated to add IPv6 support, then new MIB objects to represent IPv6 addresses will need to be added to this MIB module.

7.3.13. ATM MIB (RFC 2515)

The AToM MIB WG is currently collecting implementation reports for RFC 2515 and is considering whether to advance, revise, or retire this specification. The problems identified have been brought to the attention of the WG.

7.3.14. TN3270 MIB (RFC 2562)

The problems identified are not being addressed and a new MIB module may need to be defined.

7.3.15. Application MIB (RFC 2564)

The problems identified are not being addressed and a new MIB module may need to be defined. One possible solution might be to use the RFC 3419 TCs.

7.3.16. Definitions of Managed Objects for APPN/HPR in IP Networks

     (RFC 2584)

The problems identified are not addressed and a new MIB may be defined.

7.3.17. RADIUS MIB (RFC 2618)

The problems have not been addressed and a new MIB should be defined.

7.3.18. RADIUS Authentication Server MIB (RFC 2619)

The problems have not been addressed and a new MIB should be defined.

7.3.19. RPSL (RFC 2622)

Additional objects must be defined for IPv6 addresses and prefixes.

[10] defines extensions to solve this issue, and it is being considered for publication.

7.3.20. IPv4 Tunnel MIB (RFC 2667)

The issue is being resolved.

7.3.21. DOCSIS MIB (RFC 2669)

This problem is currently being addressed by the IPCDN WG.

7.3.22. RF MIB For DOCSIS (RFC 2670)

This problem is currently being addressed by the IPCDN WG [11].

7.3.23. VRRP MIB (RFC 2787)

The problems have not been addressed and a new MIB may need to be defined.

7.3.24. MIB For Traceroute, Pings and Lookups (RFC 2925)

The problems have not been addressed and a new MIB may need to be defined.

7.3.25. IPv4 Multicast Routing MIB (RFC 2932)

The problems have not been addressed a new MIB must be defined.

7.3.26. IGMP MIB (RFC 2933)

This problem is currently being addressed by the MAGMA WG [12].

Experimental RFCs

Protocol Independent Multicast MIB for IPv4 (RFC 2934)

The problems have not been addressed and a new MIB may need to be defined.

Security Considerations

This memo examines the IPv6-readiness of specifications; this does not have security considerations in itself.
