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.

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 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. Nesser II & Bergstrom Informational [Page 2]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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 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. 3.2. 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. 3.3. 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. 3.4. 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. 3.5. RFC 2579 Textual Conventions for SMIv2 There are no IPv4 dependencies in this specification. Nesser II & Bergstrom Informational [Page 3]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 3.6. RFC 2580 Conformance Statements for SMIv2 There are no IPv4 dependencies in this specification. 3.7. RFC 2819 Remote Network Monitoring Management Information Base There are no IPv4 dependencies in this specification. 3.8. RFC 3411 An Architecture for Describing SNMP Management Frameworks There are no IPv4 dependencies in this specification. 3.9. 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. Nesser II & Bergstrom Informational [Page 4]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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. 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 1493 Definitions of Managed Objects for Bridges There are no IPv4 dependencies in this specification. 4.2. RFC 1559 DECnet Phase IV MIB Extensions There are no IPv4 dependencies in this specification. Nesser II & Bergstrom Informational [Page 5]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 4.3. 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. 4.4. RFC 1658 Definitions of Managed Objects for Character Stream Devices using SMIv2 There are no IPv4 dependencies in this specification. 4.5. RFC 1659 Definitions of Managed Objects for RS-232-like Hardware Devices using SMIv2 There are no IPv4 dependencies in this specification. 4.6. RFC 1660 Definitions of Managed Objects for Parallel-printer-like Hardware Devices using SMIv2 There are no IPv4 dependencies in this specification. 4.7. 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 SYNTAX SEQUENCE OF IpOverSMDSEntry MAX-ACCESS not-accessible Nesser II & Bergstrom Informational [Page 6]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 STATUS current DESCRIPTION "The table of addressing information relevant to this entity's IP addresses." ::= { ipOverSMDS 1 } ipOverSMDSEntry OBJECT-TYPE SYNTAX IpOverSMDSEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The addressing information for one of this entity's IP addresses." INDEX { ipOverSMDSIndex, ipOverSMDSAddress } ::= { ipOverSMDSTable 1 } IpOverSMDSEntry ::= SEQUENCE { ipOverSMDSIndex IfIndex, 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 STATUS current Nesser II & Bergstrom Informational [Page 7]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 DESCRIPTION "The SMDS Individual address of the IP station." ::= { ipOverSMDSEntry 3 } ipOverSMDSLISGA OBJECT-TYPE SYNTAX SMDSAddress MAX-ACCESS read-only STATUS current DESCRIPTION "The SMDS Group Address that has been configured to identify the SMDS Subscriber-Network Interfaces (SNIs) of all members of the Logical IP Subnetwork (LIS) connected to the network supporting SMDS." ::= { ipOverSMDSEntry 4 } ipOverSMDSARPReq OBJECT-TYPE SYNTAX SMDSAddress MAX-ACCESS read-only STATUS current DESCRIPTION "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. 4.8. 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. 4.9. 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. Nesser II & Bergstrom Informational [Page 8]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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. 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. 5.1. RFC 1239 Reassignment of experimental MIBs to standard MIBs There are no IPv4 dependencies in this specification. 5.2. RFC 1269 Definitions of Managed Objects for the Border Gateway Protocol: Version 3 The use of BGP3 has been deprecated and is not discussed. Nesser II & Bergstrom Informational [Page 9]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 5.3. RFC 1285 FDDI Management Information Base There are no IPv4 dependencies in this specification. 5.4.

RFC 1420 SNMP over IPX 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 Nesser II & Bergstrom Informational [Page 10]

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."

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 Nesser II & Bergstrom Informational [Page 11]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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 entry, will all have their mioxPeerEncIndex values decremented by one." ::= { mioxPeerEncEntry 2 } Updated values of the first byte of these objects can be defined to support IPv6 addresses. 5.11. RFC 1471 The Definitions of Managed Objects for the Link Control Protocol of the Point-to-Point Protocol There are no IPv4 dependencies in this specification. 5.12. RFC 1472 The Definitions of Managed Objects for the Security Protocols of the Point-to-Point Protocol There are no IPv4 dependencies in this specification. 5.13. RFC 1473 The Definitions of Managed Objects for the IP Network Control Protocol of the Point-to-Point Protocol This MIB module is targeted specifically at IPv4 over PPP.

New objects need to be defined to support IPv6. Nesser II & Bergstrom Informational [Page 14]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 5.28. RFC 2012 SNMPv2 Management Information Base for the Transmission Control Protocol using SMIv2 A number of object definitions in this MIB assumes IPv4 addresses, as is noted in the note reproduced below: IESG Note: The IP, UDP, and TCP MIB modules currently support only IPv4. These three modules use the IpAddress type defined as an OCTET STRING of length 4 to represent the IPv4 32-bit internet addresses. (See RFC 1902, SMI for SNMPv2.) They do not support the new 128-bit IPv6 internet addresses. 5.29. RFC 2013 SNMPv2 Management Information Base for the User Datagram Protocol using SMIv2 A number of object definitions in this MIB assumes IPv4 addresses, as is noted in the note reproduced below: IESG Note: The IP, UDP, and TCP MIB modules currently support only IPv4.

SYNTAX OCTET STRING (SIZE (4)) Nesser II & Bergstrom Informational [Page 20]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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. 5.33. RFC 2051 Definitions of Managed Objects for APPC using SMIv2 There are no IPv4 dependencies in this specification. 5.34. RFC 2096 IP Forwarding Table MIB The MIB module's main conceptual table ipCidrRouteTable uses IPv4 addresses as index objects and is therefore incapable of representing an IPv6 forwarding information base. A new conceptual table needs to be defined to support IPv6 addresses. 5.35.

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. 5.65. RFC 2594 Definitions of Managed Objects for WWW Services There are no IPv4 dependencies in this specification. 5.66.

RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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. Nesser II & Bergstrom Informational [Page 28]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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: DocsIfCmtsCmStatusEntry ::= SEQUENCE { docsIfCmtsCmStatusIndex Integer32, docsIfCmtsCmStatusMacAddress MacAddress, docsIfCmtsCmStatusIpAddress IpAddress, docsIfCmtsCmStatusDownChannelIfIndex InterfaceIndexOrZero, docsIfCmtsCmStatusUpChannelIfIndex InterfaceIndexOrZero, docsIfCmtsCmStatusRxPower TenthdBmV, docsIfCmtsCmStatusTimingOffset Unsigned32, docsIfCmtsCmStatusEqualizationData OCTET STRING, docsIfCmtsCmStatusValue INTEGER, docsIfCmtsCmStatusUnerroreds Counter32, docsIfCmtsCmStatusCorrecteds Counter32, docsIfCmtsCmStatusUncorrectables Counter32, docsIfCmtsCmStatusSignalNoise TenthdB, docsIfCmtsCmStatusMicroreflections Integer32 } docsIfCmtsCmStatusIpAddress OBJECT-TYPE SYNTAX IpAddress MAX-ACCESS read-only STATUS current DESCRIPTION "IP address of this Cable Modem.

RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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. 5.88.

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 Nesser II & Bergstrom Informational [Page 31]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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.

RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 7. 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. 7.1. Standards 7.1.1. 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. 7.1.2. 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. 7.2. Draft Standards 7.2.1. BGP4 MIB (RFC 1657) This problem is currently being addressed by the Inter Domain Routing (IDR) WG [2]. 7.2.2. SMDS MIB (RFC 1694) See Internet Area standards. Once a specification for IPv6 over SMDS is created a new MIB must be defined. 7.2.3. RIPv2 MIB (RFC 1724) There is no updated MIB module to cover the problems outlined. A new MIB module should be defined. Nesser II & Bergstrom Informational [Page 36]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 7.2.4. OSPFv2 MIB (RFC 1850) This problem is currently being addressed by the OSPF WG [3]. 7.2.5. 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. 7.3. Proposed Standards 7.3.1. 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. 7.3.2. PPP IPCP MIB (RFC 1473) There is no updated MIB to cover the problems outlined. A new MIB should be defined. 7.3.3. 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. 7.3.4. The Definitions of Managed Objects for IP Mobility Support using SMIv2 (RFC 2006) The problems are being resolved by the MIP6 WG [4]. 7.3.5. SMIv2 IP MIB (RFC 2011) This issue is being resolved by the IPv6 WG [5]. 7.3.6. SNMPv2 TCP MIB (RFC 2012) This issue is being resolved by the IPv6 WG [6]. Nesser II & Bergstrom Informational [Page 37]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 7.3.7. SNMPv2 UDP MIB (RFC 2013) This issue is being resolved by the IPv6 WG [7]. 7.3.8. 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. 7.3.9. 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. Nesser II & Bergstrom Informational [Page 38]
RFC 3796 IPv4 in the IETF Operations & Management Area June 2004 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.
