The Institute of Electrical and Electronics Engineers (IEEE) collects and maintains a database of Organizationally Unique Identifiers (OUI). Each identifier is a 24-bit number that uniquely identifies vendors, manufactures, and other organizations. MAC addresses are generated by prefixing this 24-bit number to ensure that all devices manufactured have unique MAC addresses.
