In the task list, please click Change adapter settings. Highlight and right click the Local Area Connection icon( If your computer is connected to a wireless network please click Wireless network connection icon) click on Status and go to Details. The physical address is the MAC address of your computer will display. The physical address is the MAC address of your computer will display. In the task list, please click Manage network connections( If your computer is connected to a wireless network please click Wireless network connection icon). Highlight and right-click the Local Area Connection icon click on Status and go to Details. The physical address is the MAC address of your computer will display.Ĭlick Start -> Control Panel -> Network and Internet -> Network and Sharing Center. Highlight and right-click the Local Area Connection icon(If your computer is connected to a wireless network, please click Wireless network connection icon) click on Status and go to Support and Detail. This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI.Choose the operating system of your computer. Through Control Panel:Ĭlick Start->Control Panel->select and click Network and internet connections (If you cannot find it, please go next) ->select and double click Network Connections. 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). 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).Multicast addresses are identified by I/G = 1 and are addressed to several receivers. If I/G = 0, it is a unicast address for a single network adapter. This bit is called I/G (short for individual/group).
Bit 1 (receiver): The first bit of the MAC address specifies whether it is an individual or group address.The bit sequence of each MAC address is divided into 4 areas, each of which encodes different information.
