About OUI Lookup
How MAC address vendor identification works
The first 3 octets (24 bits) of a MAC address form the Organizationally Unique Identifier (OUI), assigned by the IEEE to hardware manufacturers.
This tool includes an embedded database of ~100 common OUI prefixes for offline lookup. For a complete database, refer to the IEEE OUI Registry.
Supported input formats: AA:BB:CC:DD:EE:FF, AA-BB-CC-DD-EE-FF, AABBCC.DDEEFF, AABBCCDDEEFF
