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.
