What is MAC Address Lookup?
A MAC address lookup identifies the hardware vendor of a network device by checking the first 3 bytes (OUI) against a database. This tool includes a local database of common OUIs from major vendors like Apple, Cisco, Intel, VMware, Raspberry Pi, and more.
It also identifies whether a MAC address is universally or locally administered.
