(In this context, the 24-bit company_id value is a portion of the 32-bit Module_Vendor_Id ROM location and related locations, and uniquely identifies hardware vendors and I/O software interface architectures)

IEEE 1596в„ў-1992 Scalable Coherent Interface.

The вЂcompany_idвЂ™ relevant standards as defined in IEEE 1212в„ў-1991 Control and Status Register (CSR) Architecture referenced by IEEE 896.2в„ў-1991 Futurebus+Physical Layers and Profiles include: The relevant standards include but not limited to: These are used in LAN and MAN applications.

The OUI defined in IEEE 802В®-2001 can be used to generate 48-bit Universal LAN MAC addresses to uniquely identify Local and Municipal Area Networks stations, and Protocol Identifiers to identify public and private protocols. It may also be used as a company identifier in those protocols and protocol standards that specify the use of a 3 octet field as a part of the protocol identification mechanism.ДЇor more information, please see the tutorial вЂњ Guidelines for Use of Extended Unique Identifier (EUI), Organizationally Unique Identifier (OUI), and Company ID (CID)вЂњ. The included OUI may also be used to generate EUI-60 (deprecated), CDI-32, TCDI-40, MAC-48 (obsolete term), create multicast addresses (per IEEE Std 802), and as a unique root for various context dependent identifiers. The OUI included in the MA-L assignment may be appended with 24 organization-supplied bits to form a EUI-48 or 40 organization-supplied bits to form an EUI-64. It is most often used to create IEEE 802-defined MAC addresses (EUI-48 and EUI-64). A MA-L assignment includes an OUI and the right to generate various extended identifiers based on that OUI.

OUI is an IEEE Registration Authority (RA) specific term that is referred to in various standards and may be used to identify companies on the IEEE Public Listing. This product was previously referred to as an OUI (Organizationally Unique Identifier) and is still referred to as such in many standards.
