The OUI (Organizationally Unique Identifier) is the first 3 octets (6 hex characters) of a MAC address. It uniquely identifies the device manufacturer or vendor, assigned by IEEE.
The vendor/manufacturer name associated with the MAC address OUI prefix. For example, looking up 00:1A:2B returns the manufacturer who owns that OUI block.
The OUI identifies the manufacturer but not the specific model. To identify the exact device, you need additional information like network scanning or device fingerprinting.
The database includes thousands of OUI entries covering major manufacturers (Apple, Samsung, Cisco, Intel, etc.) and smaller vendors. It's updated regularly with new IEEE assignments.
Yes. The OUI database is stored locally. No MAC address data is transmitted during lookups.
