MAC Address Vendor Lookup

Identify the hardware manufacturer from the first 3 bytes (OUI) of a MAC address.

What is a MAC address OUI?

A MAC address is a 48-bit hardware identifier split into two parts: the first 3 bytes (24 bits) form the OUI (Organizationally Unique Identifier) assigned by the IEEE to a manufacturer, and the last 3 bytes are device-specific. For example, E8:06:88 is an Apple OUI prefix.
