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 (IEEE) Registration Authority by the assignee (IEEE term for the vendor, manufacturer, or other organization).
The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014.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.
MAC addresses need to be individually configured on the servers by an administrator. RARP is limited to serving only IP addresses . Reverse ARP differs from the Inverse Address Resolution Protocol (InARP), which is designed to obtain the IP address associated with a local Frame Relay data link connection identifier. [ 2 ]

The Address Resolution Protocol (ARP) is a widely used communications protocol for resolving Internet layer addresses into link layer addresses.. When an Internet Protocol (IP) datagram is sent from one host to another in a local area network, the destination IP address must be resolved to a MAC address for transmission via the data link layer.
The term message integrity code (MIC) is frequently substituted for the term MAC, especially in communications [1] to distinguish it from the use of the latter as media access control address (MAC address). However, some authors [2] use MIC to refer to a message digest, which aims only to uniquely but opaquely identify a single message.
In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the ...
Another approach that has been tested is truncating the MAC Address by removing the Organizationally unique identifier (the first 24 bits of the 48 bit MAC Address). [7] However, as only 0.1% of the total Organizationally unique identifier space has been allocated and not all manufacturers fully utilise their allocated MAC Address space, this ...
