The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014. The IAB uses an OUI from the MA-L (MAC address block, large) registry, previously called the OUI registry.
An organizationally unique identifier (OUI) is a 24-bit number that uniquely identifies a vendor, manufacturer, or other organization.. OUIs are purchased from the Institute of Electrical and Electronics Engineers (IEEE) Registration Authority by the assignee (IEEE term for the vendor, manufacturer, or other organization).
The [1] IEEE Registration Authority is the administrative body that is responsible for registering and administering organizationally unique identifiers (OUI) and other types of identifiers which are used in the computer and electronics industries (Individual Address Blocks (IAB), Manufacturer IDs, Standard Group MAC Addresses, Unique Registration Numbers (URN), EtherType values, etc.)
Each WWN is an 8- or 16-byte number, the length and format of which is determined by the most significant four bits, which are referred to as an NAA (Network Address Authority). The remainder of the value is derived from an IEEE OUI (or from Company Id (CID)) and vendor-supplied information. Each format defines a different way to arrange and/or ...
Each basic service set has a unique identifier, a BSSID, which is a 48-bit number that follows MAC address conventions. [4] An infrastructure BSSID is usually non-configurable, in which case it is either preset during manufacture or mathematically derived from a preset value such as a serial number or a MAC address of another network interface.
The mobile identification number (MIN) is a number that is derived from the 10-digit directory telephone number assigned to a mobile station. The rules for deriving the MIN from the 10-digit telephone number are given in the IS-95 standard. MIN1 is the first or least significant 24 binary digits of the MIN.
Virtual machines receive a MAC address in a range that is configurable in the hypervisor. [15] Additionally some operating systems permit the end user to customise the MAC address, notably OpenWRT. [16] Usage of the node's network card MAC address for the node ID means that a version-1 UUID can be tracked back to the computer that created it.
Examples include (1) the media access control address MAC address uniquely assigned to each individual hardware network interface device produced by the manufacturer of the devices, (2) consumer product bar codes assigned to products using identifiers assigned by manufacturers that participate in GS1 identification standards, and (3) the unique ...
