What is a 36-bit Organizationally Unique ID (OUI-36)?
An OUI-36 is a 36-bit identifier that can be used as an Individual Address Block or as an extended OUI. The OUI-36 may be appended with 4 organization-supplied bits to form a 40-bit Context Dependent Identifier (CDI-40), with 12 organization-supplied bits to form an EUI-48, or with organization-supplied 28 bits to form an EUI-64. Applications making use of an OUI-36 should make no assumptions about the bit pattern that will be present in the (24-bit most-significant) OUI portion of the assigned OUI-36.
