Background
The IEEE Registration Authority was formed in 1986 at the initiative of the P802 (LAN/MAN) standards group in order to register Organizationally Unique Identifiers (OUI). Since that time, the activities of the Registration Authority have continued to expand.
In 1997, the IEEE Registration Authority assumed responsibility for the registration of EtherType Fields, as defined in the current edition of IEEE Std 802.3, and in 1998 began administering Individual Address Block assignments in an effort to preserve the OUI assignments and offer the option of obtaining a smaller amount of addresses.
In 2003, it assumed responsibility for administering, allocating and managing the Logical Link Control (LLC) and Standard Group MAC addresses. IEEE has become the single point of contact with respect to all information associated with LAN addresses.
In 2004, IEEE established three registration authorities associated with IEEE 1451.4-2004. They are:
On 27 April 2007, three additional registries were launched. Unlike the registries launched in 2004, each registry represents a different IEEE standard.
The IEEE Registration Authority formerly had administrative responsibility for the IEEE POSIX® Certification. Authority.
