MAC vendor lookup
Identify the manufacturer of any network device from its MAC address via the IEEE OUI database.
Examples
How it works: The first 3 octets (24 bits) of a MAC address form the OUI (Organizationally Unique Identifier), assigned by the IEEE to manufacturers. Lookups run entirely in your browser against the bundled IEEE MA-L OUI database (~39,000 entries). No data is sent anywhere.
