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. 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). Step 1: Open the terminal of your operating system.
