Introduction + + Some IETF protocols use Ethernet or other IEEE 802-related + communication frame formats and parameters [IEEE802]. These include + MAC (Media Access Control) identifiers and protocol identifiers. + + This document specifies IANA considerations for the assignment of + code points under the IANA OUI. It also discusses several other uses + by the IETF of IEEE 802 code points and provides some values for use + in documentation. As noted in [RFC2606] and [RFC5737], the use of + designated code values reserved for documentation and examples + reduces the likelihood of conflicts and confusion arising from their + duplication of code points assigned for some deployed use. + + [RFC5226] is incorporated herein except where there are contrary + provisions in this document. In this document, "IESG Ratification" + is used in some cases, and it is specified in Section 5.1. This is + not the same as "IESG Approval" in [RFC5226]. + +1.1. Notations Used in This Document + + This document uses hexadecimal notation. Each octet (that is, 8-bit + byte) is represented by two hexadecimal digits giving the value of + the octet as an unsigned integer. Successive octets are separated by + a hyphen. This document consistently uses IETF bit ordering although + the physical order of bit transmission within an octet on an IEEE + [802.3] link is from the lowest order bit to the highest order bit + (i.e., the reverse of the IETF's ordering). + + In this document: + + "AFN" stands for Address Family Number [RFC4760]. + + "EUI" stands for Extended Unique Identifier. + + "IAB" stands for Individual Address Block, not for Internet + Architecture Board. + + "MAC" stands for Media Access Control, not for Message + Authentication Code. + + "OUI" stands for Organizationally Unique Identifier. + + "RRTYPE" stands for a DNS Resource Record type [RFC6895]. + + "**" indicates exponentiation. For example, 2**24 is two to the + twenty-fourth power. + + + + +Eastlake & Abley BCP [Page 4] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +1.2. Changes from RFC 5342 + + o Added MAC addresses and IANA OUI-based protocol and other values + for use in documentation, and added relevant Security + Considerations language. + + o Eliminated any requirements for parallel unicast and multicast + assignment unless requested. Such requirements had been included + in [RFC5342] on the theory they would make bookkeeping easier for + IANA but they have proved to be problematic in practice. + + o Re-casted informational material about relevant IEEE assignment + policies to take into account [RAC-OUI]. + + o Added AFNs and RRTYPEs for 48-bit and 64-bit MACs. + +1.3. The IEEE Registration Authority + + Originally the responsibility of Xerox Corporation, the registration + authority for Ethernet parameters is now the IEEE Registration + Authority, available on the web at: + + http://standards.ieee.org/regauth/ + + Anyone may apply to that Authority for parameters. They may impose + fees or other requirements but commonly waive fees for applications + from standards development organizations. + + A list of some assignments and their holders is downloadable from the + IEEE Registration Authority site. + +1.4. The IANA OUI + + The OUI 00-00-5E has been assigned to IANA. + + There is no OUI value reserved at this time for documentation, but + there are documentation code points under the IANA OUI specified + below. + +2. Ethernet Identifier Parameters + + Section 2.1 discusses EUI-48 (Extended Unique Identifier 48) MAC + identifiers, their relationship to OUIs and other prefixes, and + assignments under the IANA OUI. Section 2.2 extends this to EUI-64 + identifiers. Section 2.3 discusses other IETF MAC identifier use not + under the IANA OUI. + + + + + +Eastlake & Abley BCP [Page 5] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + [RAC-OUI] indicates that the IEEE Registration Authority Committee is + exploring the feasibility of defining a new "EUI-128" identifier. + +2.1. 48-Bit MAC Identifiers, OUIs, and Other Prefixes + + 48-bit MAC "addresses" are the most commonly used Ethernet interface + identifiers. Those that are globally unique are also called EUI-48 + identifiers. An EUI-48 is structured into an initial 3-octet OUI + (Organizationally Unique Identifier) and an additional 3 octets + assigned by the OUI holder or into a larger initial prefix assigned + to an organization and a shorter sequence of additional bits so as to + add up to 48 bits in total. For example, the IEEE has assigned IABs + (Individual Address Blocks), where the first 4 1/2 octets (36 bits) + are assigned, giving the holder of the IAB 1 1/2 octets (12 bits) + they can control; however, IABs will become historic, and a wider + range of prefix lengths will be made available [RAC-OUI]. + + The IEEE describes its assignment procedures and policies for IEEE + 802-related identifiers in [802_O&A], which is being revised. + + Two bits within the initial octet of an EUI-48 have special + significance in MAC addresses: the Group bit (01) and the Local bit + (02). OUIs and longer MAC prefixes are assigned with the Local bit + zero and the Group bit unspecified. Multicast identifiers may be + constructed by turning on the Group bit, and unicast identifiers may + be constructed by leaving the Group bit zero. + + The Local bit is zero for globally unique EUI-48 identifiers assigned + by the owner of an OUI or owner of a longer prefix. If the Local bit + is a one, the identifier has been considered by IEEE 802 to be a + local identifier under the control of the local network + administrator; however, there may be emerging recommendations from + the IEEE Registration Authority on management of the local address + space. If the Local bit is on, the holder of an OUI has no special + authority over MAC identifiers whose first 3 octets correspond to + their OUI. + + An AFN and a DNS RRTYPE have been assigned for 48-bit MAC addresses + (see Section 5.2). + +2.1.1. EUI-48 Assignments under the IANA OUI + + The OUI 00-00-5E has been assigned to IANA as stated in Section 1.4 + above. This includes 2**24 EUI-48 multicast identifiers from + 01-00-5E-00-00-00 to 01-00-5E-FF-FF-FF and 2**24 EUI-48 unicast + identifiers from 00-00-5E-00-00-00 to 00-00-5E-FF-FF-FF. + + + + + +Eastlake & Abley BCP [Page 6] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + Of these EUI-48 identifiers, the sub-blocks reserved or thus far + assigned by IANA for purposes of documentation are as follows: + + Unicast, all blocks of 2**8 addresses thus far: + + 00-00-5E-00-00-00 through 00-00-5E-00-00-FF: reserved and require + IESG Ratification for assignment (see Section 5.1). + + 00-00-5E-00-01-00 through 00-00-5E-00-01-FF: assigned for the + Virtual Router Redundancy Protocol (VRRP) [RFC5798]. + + 00-00-5E-00-02-00 through 00-00-5E-00-02-FF: assigned for the IPv6 + Virtual Router Redundancy Protocol (IPv6 VRRP) [RFC5798]. + + 00-00-5E-00-52-00 through 00-00-5E-00-52-FF: used for very small + assignments. Currently, 3 out of these 256 values have been + assigned. + + 00-00-5E-00-53-00 through 00-00-5E-00-53-FF: assigned for use in + documentation. + + Multicast: + + 01-00-5E-00-00-00 through 01-00-5E-7F-FF-FF: 2**23 addresses + assigned for IPv4 multicast [RFC1112]. + + 01-00-5E-80-00-00 through 01-00-5E-8F-FF-FF: 2**20 addresses + assigned for MPLS multicast [RFC5332]. + + 01-00-5E-90-00-00 through 01-00-5E-90-00-FF: 2**8 addresses being + used for very small assignments. Currently, 4 out of these 256 + values have been assigned. + + 01-00-5E-90-10-00 through 01-00-5E-90-10-FF: 2**8 addresses for + use in documentation. + + For more detailed and up-to-date information, see the "Ethernet + Numbers" registry at http://www.iana.org. + +2.1.2. EUI-48 Documentation Values + + The following values have been assigned for use in documentation: + + 00-00-5E-00-53-00 through 00-00-5E-00-53-FF for unicast and + + 01-00-5E-90-10-00 through 01-00-5E-90-10-FF for multicast. + + + + + +Eastlake & Abley BCP [Page 7] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +2.1.3. EUI-48 IANA Assignment Considerations + + EUI-48 assignments under the current or a future IANA OUI (see + Section 5.4) must meet the following requirements: + + o must be for standards purposes (either for an IETF Standard or + other standard related to IETF work), + + o must be for a power-of-two size block of identifiers starting + at a boundary that is an equal or greater power of two, + including the assignment of one (2**0) identifier, + + o must not be used to evade the requirement for vendors to obtain + their own block of identifiers from the IEEE, and + + o must be documented in an Internet-Draft or RFC. + + In addition, approval must be obtained as follows (see the procedure + in Section 5.1): + + Small to medium assignments of a block of 1, 2, 4, ..., 32768, + 65536 (2**0, 2**1, 2**2, ..., 2**15, 2**16) EUI-48 identifiers + require Expert Review (see Section 5.1). + + Large assignments of 131072 (2**17) or more EUI-48 identifiers + require IESG Ratification (see Section 5.1). + + ([RFC5342] had a requirement for parallel unicast and multicast + assignments under some circumstances even when one of the types was + not included in the application. That requirement has proved + impractical and is eliminated in this document.) + +2.2. 64-Bit MAC Identifiers + + IEEE also defines a system of 64-bit MAC identifiers including + EUI-64s. EUI-64 identifiers are currently used as follows: + + o In a modified form to construct some IPv6 interface identifiers + as described in Section 2.2.1 + + o In IEEE Std 1394 (also known as FireWire and i.Link) + + o In IEEE Std 802.15.4 (also known as ZigBee) + + o In [InfiniBand] + + + + + + +Eastlake & Abley BCP [Page 8] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + Adding a 5-octet (40-bit) extension to a 3-octet (24-bit) OUI, or a + shorter extension to longer assigned prefixes [RAC-OUI] so as to + total 64 bits, produces an EUI-64 identifier under that OUI or longer + prefix. As with EUI-48 identifiers, the first octet has the same + Group and Local bits. + + An AFN and a DNS RRTYPE have been assigned for 64-bit MAC addresses + (see Section 5.2). + + The discussion below is almost entirely in terms of the "Modified" + form of EUI-64 identifiers; however, anyone assigned such an + identifier can also use the unmodified form as a MAC identifier on + any link that uses such 64-bit identifiers for interfaces. + +2.2.1. IPv6 Use of Modified EUI-64 Identifiers + + MAC-64 identifiers are used to form the lower 64 bits of some IPv6 + addresses (Section 2.5.1 and Appendix A of [RFC4291] and Appendix A + of [RFC5214]). When so used, the MAC-64 is modified by inverting the + Local/Global bit to form an IETF "Modified EUI-64 identifier". Below + is an illustration of a Modified EUI-64 unicast identifier under the + IANA OUI, where aa-bb-cc-dd-ee is the extension. + + 02-00-5E-aa-bb-cc-dd-ee + + The first octet is shown as 02 rather than 00 because, in Modified + EUI-64 identifiers, the sense of the Local/Global bit is inverted + compared with EUI-48 identifiers. It is the globally unique values + (universal scope) that have the 02 bit on in the first octet, while + those with this bit off are locally assigned and out of scope for + global assignment. + + The Local/Global bit was inverted to make it easier for network + operators to type in local-scope identifiers. Thus, such Modified + EUI-64 identifiers as 1, 2, etc. (ignoring leading zeros) are local. + Without the modification, they would have to be + 02-00-00-00-00-00-00-01, 02-00-00-00-00-00-00-02, etc. to be local. + + As with MAC-48 identifiers, the 01 bit on in the first octet + indicates a group identifier. + + When the first two octets of the extension of a Modified EUI-64 + identifier are FF-FE, the remainder of the extension is a 24-bit + value as assigned by the OUI owner for an EUI-48. For example: + + 02-00-5E-FF-FE-yy-yy-yy + or + 03-00-5E-FF-FE-yy-yy-yy + + + +Eastlake & Abley BCP [Page 9] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + where yy-yy-yy is the portion (of an EUI-48 global unicast or + multicast identifier) that is assigned by the OUI owner (IANA in this + case). Thus, any holder of one or more EUI-48 identifiers under the + IANA OUI also has an equal number of Modified EUI-64 identifiers that + can be formed by inserting FF-FE in the middle of their EUI-48 + identifiers and inverting the Local/Global bit. + + (Note: [EUI-64] defines FF-FF as the bits to be inserted to create + an IEEE EUI-64 identifier from a MAC-48 identifier. That document + says the FF-FE value is used when starting with an EUI-48 + identifier. The IETF uses only FF-FE to create Modified EUI-64 + identifiers from 48-bit Ethernet station identifiers regardless of + whether they are EUI-48 or MAC-48 local identifiers. EUI-48 and + local MAC-48 identifiers are syntactically equivalent, and this + doesn't cause any problems in practice.) + + In addition, certain Modified EUI-64 identifiers under the IANA OUI + are reserved for holders of IPv4 addresses as follows: + + 02-00-5E-FE-xx-xx-xx-xx + + where xx-xx-xx-xx is a 32-bit IPv4 address. The owner of an IPv4 + address has both the unicast- and multicast-derived EUI-64 address. + Modified EUI-64 identifiers from + + 02-00-5E-FE-F0-00-00-00 to 02-00-5E-FE-FF-FF-FF-FF + + are effectively reserved pending the specification of IPv4 Class E + addresses. However, for Modified EUI-64 identifiers based on an IPv4 + address, the Local/Global bit should be set to correspond to whether + the IPv4 address is local or global. (Keep in mind that the sense of + the Modified EUI-64 identifier Local/Global bit is reversed from that + in (unmodified) MAC-64 identifiers.) + +2.2.2. EUI-64 IANA Assignment Considerations + + The following table shows which Modified EUI-64 identifiers under the + IANA OUI are reserved, assigned, or available as indicated. As noted + above, the corresponding MAC addresses can be determined by + complementing the 02 bit in the first octet. In all cases, the + corresponding multicast 64-bit MAC addresses formed by complementing + the 01 bit in the first octet have the same status as the modified + 64-bit unicast address blocks listed below. + + 02-00-5E-00-00-00-00-00 to 02-00-5E-0F-FF-FF-FF-FF reserved + + 02-00-5E-10-00-00-00-00 to 02-00-5E-10-00-00-00-FF assigned for + documentation use + + + +Eastlake & Abley BCP [Page 10] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + 02-00-5E-10-00-00-01-00 to 02-00-5E-EF-FF-FF-FF-FF, which is + available for assignment + + 02-00-5E-F0-00-00-00-00 to 02-00-5E-FD-FF-FF-FF-FF reserved + + 02-00-5E-FE-00-00-00-00 to 02-00-5E-FE-FF-FF-FF-FF assigned to + IPv4 address holders as described above + + 02-00-5E-FF-00-00-00-00 to 02-00-5E-FF-FD-FF-FF-FF reserved + + 02-00-5E-FF-FE-00-00-00 to 02-00-5E-FF-FE-FF-FF-FF assigned for + holders of EUI-48 identifiers under the IANA OUI as described + above + + 02-00-5E-FF-FF-00-00-00 to 02-00-5E-FF-FF-FF-FF-FF reserved + + The reserved identifiers above require IESG Ratification (see + Section 5.1) for assignment. IANA EUI-64 identifier assignments + under the IANA OUI must meet the following requirements: + + o must be for standards purposes (either for an IETF Standard or + other standard related to IETF work), + + o must be for a power-of-two size block of identifiers starting + at a boundary that is an equal or greater power of two, + including the assignment of one (2**0) identifier, + + o must not be used to evade the requirement for vendors to obtain + their own block of identifiers from the IEEE, and + + o must be documented in an Internet-Draft or RFC. + + In addition, approval must be obtained as follows (see the procedure + in Section 5.1): + + Small to medium assignments of a block of 1, 2, 4, ..., 134217728, + 268435456 (2**0, 2**1, 2**2, ..., 2**27, 2**28) EUI-64 + identifiers require Expert Review (see Section 5.1). + + Assignments of any size, including 536870912 (2**29) or more + EUI-64 identifiers, may be made with IESG Ratification (see + Section 5.1). + + + + + + + + + +Eastlake & Abley BCP [Page 11] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +2.2.3.

Other MAC-48 Identifiers Used by the IETF + + There are two other blocks of MAC-48 identifiers that are used by the + IETF as described below. + +2.3.1. Identifiers Prefixed "33-33" + + All MAC-48 multicast identifiers prefixed "33-33" (that is, the 2**32 + multicast MAC identifiers in the range from 33-33-00-00-00-00 to + 33-33-FF-FF-FF-FF) are used as specified in [RFC2464] for IPv6 + multicast. In all of these identifiers, the Group bit (the bottom + + + +Eastlake & Abley BCP [Page 12] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + bit of the first octet) is on, as is required to work properly with + existing hardware as a multicast identifier. They also have the + Local bit on and are used for this purpose in IPv6 networks. + + (Historical note: It was the custom during IPv6 design to use "3" + for unknown or example values, and 3333 Coyote Hill Road, Palo + Alto, California, is the address of PARC (Palo Alto Research + Center, formerly "Xerox PARC"). Ethernet was originally specified + by the Digital Equipment Corporation, Intel Corporation, and Xerox + Corporation. The pre-IEEE [802.3] Ethernet protocol has sometimes + been known as "DIX" Ethernet from the first letters of the names + of these companies.) + +2.3.2. The 'CF Series' + + The Informational [RFC2153] declared the 3-octet values from CF-00-00 + through CF-FF-FF to be OUIs available for assignment by IANA to + software vendors for use in PPP [RFC1661] or for other uses where + vendors do not otherwise need an IEEE-assigned OUI. It should be + noted that, when used as MAC-48 prefixes, these values have the Local + and Group bits on, while all IEEE-assigned OUIs thus far have those + bits off. The Group bit is meaningless in PPP. To quote [RFC2153]: + "The 'CF0000' series was arbitrarily chosen to match the PPP NLPID + 'CF', as a matter of mnemonic convenience." + + CF-00-00 is reserved, and IANA lists multicast identifier + CF-00-00-00-00-00 as used for Ethernet loopback tests. + + In over a decade of availability, only a handful of values in the + 'CF Series' have been assigned. (See "Ethernet Numbers" + <http://www.iana.org/assignments/ethernet-numbers> and "PPP Numbers" + <http://www.iana.org/assignments/ppp-numbers>). + +2.3.2.1. Changes to RFC 2153 + + The IANA Considerations in [RFC2153] were updated as follows by the + approval of [RFC5342] (no technical changes were made at that time): + + o Use of these identifiers based on IANA assignment was + deprecated. + + o IANA was instructed not to assign any further values in the + 'CF Series'. + + + + + + + + +Eastlake & Abley BCP [Page 13] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +3. Ethernet Protocol Parameters + + Ethernet protocol parameters provide a means of indicating the + contents of a frame -- for example, that its contents are IPv4 or + IPv6. + + The concept has been extended to labeling by "tags". A tag in this + sense is a prefix whose type is identified by an Ethertype that is + then followed by either another tag, an Ethertype, or an LSAP (Link- + Layer Service Access Point) protocol indicator for the "main" body of + the frame, as described below. Traditionally, in the [802_O&A] + world, tags are a fixed length and do not include any encoding of + their own length. Any device that is processing a frame cannot, in + general, safely process anything in the frame past an Ethertype it + does not understand. An example is the C-Tag (formerly the Q-Tag) + [802.1Q]. It provides customer VLAN and priority information for a + frame. + + There are two types of protocol identifier parameters that can occur + in Ethernet frames after the initial MAC-48 destination and source + identifiers: + + Ethertypes: These are 16-bit identifiers appearing as the initial + two octets after the MAC destination and source (or after a + tag), which, when considered as an unsigned integer, are equal + to or larger than 0x0600. + + LSAPs: These are 8-bit protocol identifiers that occur in pairs + immediately after an initial 16-bit (two-octet) remaining frame + length, which is in turn after the MAC destination and source + (or after a tag). Such a length must, when considered as an + unsigned integer, be less than 0x5DC, or it could be mistaken + as an Ethertype. LSAPs occur in pairs where one is intended to + indicate the source protocol handler and one the destination + protocol handler; however, use cases where the two are + different have been relatively rare. + + Neither Ethertypes nor LSAPs are assigned by IANA; they are assigned + by the IEEE Registration Authority (see Section 1.3 above and + Appendix B). However, both LSAPs and Ethertypes have extension + mechanisms so that they can be used with five-octet Ethernet protocol + identifiers under an OUI, including those assigned by IANA under the + IANA OUI. + + + + + + + + +Eastlake & Abley BCP [Page 14] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + When using the IEEE 802 Logical Link Control (LLC) format (Subnetwork + Access Protocol (SNAP)) [802_O&A] for a frame, an OUI-based protocol + identifier can be expressed as follows: + + xx-xx-AA-AA-03-yy-yy-yy-zz-zz + + where xx-xx is the frame length and, as above, must be small enough + not to be confused with an Ethertype; "AA" is the LSAP that indicates + this use and is sometimes referred to as the SNAP Service Access + Point (SAP); "03" is the LLC control octet indicating datagram + service; yy-yy-yy is an OUI; and zz-zz is a protocol number, under + that OUI, assigned by the OUI owner. The odd five-octet length for + such OUI-based protocol identifiers was chosen so that, with the LLC + control octet ("03"), the result is 16-bit aligned. + + When using an Ethertype to indicate the main type for a frame body, + the special "OUI Extended Ethertype" 88-B7 is available. Using this + Ethertype, a frame body can begin with + + 88-B7-yy-yy-yy-zz-zz + + where yy-yy-yy and zz-zz have the same meaning as in the SNAP format + described above. + + It is also possible, within the SNAP format, to use an arbitrary + Ethertype. Putting the Ethertype as the zz-zz field after an all- + zeros OUI (00-00-00) does this. It looks like + + xx-xx-AA-AA-03-00-00-00-zz-zz + + where zz-zz is the Ethertype. + + (Note that, at this point, the 802 protocol syntax facilities are + sufficiently powerful that they could be chained indefinitely. + Whether support for such chaining is generally required is not + clear, but [802_O&A] requires support for + + xx-xx-AA-AA-03-00-00-00-88-B7-yy-yy-yy-zz-zz + + although this could be more efficiently expressed by simply + pinching out the "00-00-00-88-B7" in the middle.) + + As well as labeling frame contents, 802 protocol types appear within + NBMA (Non-Broadcast Multi-Access) Next Hop Resolution Protocol + [RFC2332] messages. Such messages have provisions for both two-octet + Ethertypes and OUI-based protocol types. + + + + + +Eastlake & Abley BCP [Page 15] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +3.1. Ethernet Protocol Assignment under the IANA OUI + + Two-octet protocol numbers under the IANA OUI are available, as in + + xx-xx-AA-AA-03-00-00-5E-qq-qq + + where qq-qq is the protocol number. + + A number of such assignments have been made out of the 2**16 protocol + numbers available from 00-00-5E-00-00 to 00-00-5E-FF-FF (see [IANA]). + The extreme values of this range, 00-00-5E-00-00 and 00-00-5E-FF-FF, + are reserved and require IESG Ratification for assignment (see + Section 5.1). New assignments of SNAP SAP protocol (qq-qq) numbers + under the IANA OUI must meet the following requirements: + + o the assignment must be for standards use (either for an IETF + Standard or other standard related to IETF work), + + o it must be documented in an Internet-Draft or RFC, and + + o such protocol numbers are not to be assigned for any protocol + that has an Ethertype (because that can be expressed by putting + an all-zeros "OUI" before the Ethertype as described above). + + In addition, the Expert Review (or IESG Ratification for the two + reserved values) must be obtained using the procedure specified in + Section 5.1. + +3.2. Documentation Protocol Number + + 0x0042 is a protocol number under the IANA OUI (that is, + 00-00-5E-00-42) to be used for documentation purposes. + +4. Other OUI-Based Parameters + + Some IEEE 802 and other protocols provide for parameters based on an + OUI beyond those discussed above. Such parameters most commonly + consist of an OUI plus one octet of additional value. They are + usually called "vendor specific" parameters, although "organization + specific" might be more accurate. They would look like + + yy-yy-yy-zz + + where yy-yy-yy is the OUI and zz is the additional specifier. An + example is the Cipher Suite Selector in IEEE [802.11]. + + Values may be assigned under the IANA OUI for such other OUI-based + parameter usage by Expert Review except that, for each use, the + + + +Eastlake & Abley BCP [Page 16] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + additional specifier values consisting of all zero bits and all one + bits (0x00 (00-00-5E-00) and 0xFF (00-00-5E-FF) for a one-octet + specifier) are reserved and require IESG Ratification (see + Section 5.1) for assignment; also, the additional specifier value + 0x42 (00-00-5E-42) is assigned for use in documentation. + + Assignments of such other IANA OUI-based parameters must be for + standards use (either for an IETF Standard or other standard related + to IETF work) and be documented in an Internet-Draft or RFC. The + first time a value is assigned for a particular parameter of this + type, an IANA registry will be created to contain that assignment and + any subsequent assignments of values for that parameter under the + IANA OUI. The Expert will specify the name of the registry. + + If different policies from those above are required for such a + parameter, a BCP or Standards Track RFC must be adopted to update + this BCP and specify the new policy and parameter. + +5. IANA Considerations + + The entirety of this document concerns IANA considerations for the + assignment of Ethernet parameters in connection with the IANA OUI and + related matters. + + As this document replaces [RFC5342], references to [RFC5342] in IANA + registries have been replaced by references to this document. In + addition, any references in the registries to [DOC-ADDR], which has + been combined into this document, have been replaced by references to + this document. + + This document does not create any new IANA registries. + + This document assigns MAC address values for documentation. These + values had been previously assigned by [DOC-ADDR]; as noted above, + any references in the registries to [DOC-ADDR] have been replaced by + references to this document. + + The only other assignment that has been made by this document is a + protocol number for documentation. See Section 5.6 for details. + + No existing assignment is changed by this document. + +5.1. Expert Review and IESG Ratification + + This section specifies the procedure for Expert Review and IESG + Ratification of MAC, protocol, and other IANA OUI-based identifiers. + The Expert(s) referred to in this document shall consist of one or + more persons appointed by and serving at the pleasure of the IESG. + + + +Eastlake & Abley BCP [Page 17] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + The procedure described for Expert Review assignments in this + document is fully consistent with the IANA Expert Review policy + described in [RFC5226]. + + While finite, the universe of code points from which Expert-judged + assignments will be made is felt to be large enough that the + requirements given in this document and the Experts' good judgment + are sufficient guidance. The idea is for the Expert to provide a + light sanity check for small assignments of EUI identifiers, with + increased scrutiny by the Expert for medium-sized assignments of EUI + identifiers and assignments of protocol identifiers and other IANA + OUI-based parameters. However, it can make sense to assign very + large portions of the MAC identifier code point space. (Note that + existing assignments include one for 1/2 of the entire multicast IANA + EUI-48 code point space and one for 1/16 of that multicast code point + space.) In those cases, and in cases of the assignment of "reserved" + values, IESG Ratification of an Expert Review approval recommendation + is required as described below. The procedure is as follows: + + The applicant always completes the appropriate template from + Appendix A below and sends it to IANA <iana@iana.org>. + + IANA always sends the template to an appointed Expert. If the + Expert recuses themselves or is non-responsive, IANA may choose + an alternative appointed Expert or, if none is available, will + contact the IESG. + + In all cases, if IANA receives a disapproval from an Expert + selected to review an application template, the application + will be denied. + + If the assignment is based on Expert Review: + + If IANA receives approval and code points are available, + IANA will make the requested assignment. + + If the assignment is based on IESG Ratification: + + The procedure starts with the first steps above for Expert + Review. If the Expert disapproves the application, they + simply inform IANA; however, if the Expert believes the + application should be approved, or is uncertain and believes + that the circumstances warrant the attention of the IESG, + the Expert will inform IANA about their advice, and IANA + will forward the application, together with the reasons for + approval or uncertainty, to the IESG. The IESG must decide + whether the assignment will be granted. This can be + accomplished by a management item in an IESG telechat as is + + + +Eastlake & Abley BCP [Page 18] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + + done for other types of requests. If the IESG decides not + to ratify a favorable opinion by the Expert or decides + against an application where the Expert is uncertain, the + application is denied; otherwise, it is granted. The IESG + will communicate its decision to the Expert and to IANA. + +5.2. MAC Address AFNs and RRTYPEs + + IANA has assigned Address Family Numbers (AFNs) for MAC addresses as + follows: + + AFN Decimal Hex Reference + ---------- ------- ------ --------- + 48-bit MAC 16389 0x4005 [RFC7042] + 64-bit MAC 16390 0x4006 [RFC7042] + + IANA has assigned DNS RRTYPEs [RFC6895] for MAC addresses as follows: + + RRTYPE Code + Data Mnemonic Decimal Hex Reference + ---------- -------- ------- ------ ----------- + 48-bit MAC EUI48 108 0x006C [RFC7043] + 64-bit MAC EUI64 109 0x006D [RFC7043] + +5.3. Informational IANA Web Page Material + + IANA maintains an informational listing on its web site concerning + Ethertypes, OUIs, and multicast addresses assigned under OUIs other + than the IANA OUI. The title of this informational registry is "IEEE + 802 Numbers". IANA has merged in those Ethertypes listed in Appendix + B that were not already included. IANA will update that + informational registry when changes are provided by the Expert. + +5.4. OUI Exhaustion + + When the available space for either multicast or unicast EUI-48 + identifiers under OUI 00-00-5E has been 90% or more exhausted, IANA + should request an additional OUI from the IEEE Registration Authority + for further IANA assignment. The appointed Expert(s) should monitor + for this condition and notify IANA. + +5.5. IANA OUI MAC Address Table + + No changes have been made in the "IANA Unicast 48-bit MAC Addresses" + and "IANA Multicast 48-bit MAC Addresses" tables except for the + updates to references as specified in the first part of Section 5. + + + + + +Eastlake & Abley BCP [Page 19] + +RFC 7042 IANA/IETF and IEEE 802 Parameters October 2013 + + +5.6. SNAP Protocol Number Table and Assignment + + The "SNAP PROTOCOL IDs" table has been renamed the "SNAP Protocol + Numbers" table. "PID" has been replaced by "Protocol Number". + + IANA has assigned 0x0042 as the SNAP protocol number under the IANA + OUI to be used for documentation purposes. + +6. Security Considerations + + This document is concerned with assignment of parameters under the + IANA OUI and closely related matters. It is not directly concerned + with security except as follows. + + Confusion and conflict can be caused by the use of MAC addresses or + other OUI-derived protocol parameters as examples in documentation. + Examples used "only" in documentation can end up being coded and + released or cause conflicts due to later real use and the possible + acquisition of intellectual property rights in such addresses or + parameters. The reservation herein of MAC addresses and parameters + for documentation purposes will minimize such confusion and conflict. + + See [RFC7043] for security considerations in storing MAC addresses in + the DNS. + +7.
