The Individual Address Block (IAB) is an inactive registry which has been replaced by the MA-S (MAC address block, small), previously named OUI-36, and has no overlaps in addresses with the IAB [6] registry product as of January 1, 2014.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.
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 ...
Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...
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.

HMAC-SHA1 generation. In cryptography, an HMAC (sometimes expanded as either keyed-hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.
ISO/IEC 9797-1 Information technology – Security techniques – Message Authentication Codes (MACs) – Part 1: Mechanisms using a block cipher [1] is an international standard that defines methods for calculating a message authentication code (MAC) over data.
The Address Resolution Protocol (ARP) is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address. The protocol, part of the Internet protocol suite , was defined in 1982 by RFC 826 , which is Internet Standard STD 37.
