Organizationally Unique Identifier
From Wikipedia, the free encyclopedia
An Organizationally Unique Identifier (or OUI) is a 24-bit number assigned by the IEEE Registration Authority to a company or organization for use in various computer hardware products, including MAC addresses for Ethernet and other network interface cards and World Wide Names for Fibre Channel host bus adapters.
In MAC addresses, the OUI is combined with an internally-assigned 24-bit number to form the address. The first three octets of the address are the OUI.
