This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI.

Bit 25-48 (network adapter identifier): Bits 25 to 48 provide device manufacturers with 24 bits for assigning a unique hardware identifier (organizationally unique address, OUA).

A corresponding service is available, for example, on . Every network-compatible device can be identified by its MAC (media access control) address, a unique 17-character string of letters, numbers and colons. The assignment of OUIs is usually public and can be determined via databases.

Bit 3–24 (manufacturer identification): Bits 3 to 24 encode an identifier (organizationally unique identifier, OUI), which is assigned exclusively to hardware manufacturers by IEEE.

Addresses that are only locally unique are called locally administered address (LAA) and are marked with U/L = 1. If U/L = 0, the address is valid worldwide as a universally administered address (UAA).

Bit 2 (registry): The second bit of the MAC address indicates whether it is an address with global validity (universal) or whether the address has been assigned locally (local).

Search vendor, manufacturer or organization of a device by MAC/OUI address. Multicast addresses are identified by I/G = 1 and are addressed to several receivers. Fast and easy MAC address lookup on IEEE directory and Wireshark manufacturer database. If I/G = 0, it is a unicast address for a single network adapter. In the right pane, select Hardware Properties.
