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.

FAQ

What is an OUI?

What does 'locally administered' mean?
A locally administered MAC address has been manually set (e.g., by a hypervisor) rather than burned into the hardware by the manufacturer.
