2013-04-10 This page has assignments by IANA as specified in to be under the IANA OUI. For some information on IEEE 802 number assignments by the IEEE Registration Authority and how to contact that authority, see the . Dan Romascanu See IANA allocates addresses under the IANA OUI (00-00-5E) as explained in . Unicast address under the IANA OUI start with 00-00-5E, while multicast addresses under the IANA OUI start with 01-00-5E. In the lists below, these initial 3 bytes are omitted for brevity. As described in , 48-bit MAC addresses in the range 33-33-00-00-00-00 to 33-33-FF-FF-FF-FF are used for IPv6 multicast. These values are prefixed with 00-00-5E. 00-00-00 to 00-00-FF Reserved 00-01-00 to 00-01-FF VRRP (Virtual Router Redundancy Protocol) 00-02-00 to 00-02-FF VRRP IPv6 (Virtual Router Redundancy Protocol IPv6) 00-03-00 to 00-51-FF Unassigned 00-52-00 PacketPWEthA 00-52-01 PacketPWEthB 00-52-02 to 00-52-12 Unassigned (small allocations) 00-52-13 Proxy Mobile IPv6 00-52-14 to 00-52-FF Unassigned (small allocations) 00-53-00 to 00-53-FF Documentation 00-54-00 to FF-FF-FF Unassigned These values are prefixed with 01-00-5E. 00-00-00 to 7F-FF-FF IPv4 Multicast 80-00-00 to 8F-FF-FF MPLS Multicast 90-00-00 MPLS-TP p2p 90-00-01 Bidirectional Forwarding Detection (BFD) on Link Aggregation Group (LAG) Interfaces 90-00-02 AllL1MI-ISs 90-00-03 AllL2MI-ISs 90-00-04 to 90-00-FF Unassigned (small allocations) 90-01-00 to 90-0F-FF Unassigned 90-10-00 to 90-10-FF Documentation 90-11-00 to FF-FF-FF Unassigned These values are prefixed with 02-00-5E for unicast or 03-00-5E for multicast.
