The first 24 bits, known as the Organizationally Unique Identifier or OUI, identify the manufacturer of a NIC card. The OUI is assigned to manufacturers by the Institute of Electrical and Electronics Engineers (IEEE) and is unique to each manufacturer. By looking up the OUI in a database such as the IEEE's publicly available database, the manufacturer of the NIC card can be determined.
