This means that 2 24 (= 16.777.216) unique OUAs can be assigned per OUI. Look for ‘Physical address (MAC)’ at the bottom of the page. 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.MACINTOSH OS 10.5 (Leopard) Look under Ethernet ID for the Wired Connectionand. To find the wireless MAC address, select Airport from the pull -down menu. In the Status window that appears, click Details. Next to Connections, click on the connection name. Step 3: The information about the IP configuration of your computer and the Physical Address of your network card are displayed. Step 2: In CMD, type the command ipconfig /all and then press the Enter key.

The MAC address is listed as series of 12 digits, listed as the Physical Address (00:1A:C2:7B:00:47, for example). Type ipconfig /all (note the space between the g and /).

Click on the Start Menu, then select Run. Step 1: Click on start button and type CMD. To find the MAC address on your Windows computer: Click on the Start menu in the bottom-left corner of your computer. Under the Ethernet Adapter Local Area Connection section, look for the 'Physical Address'. In the Command Prompt window, type ipconfig /all and press Enter. Addresses that are only locally unique are called locally administered address (LAA) and are marked with U/L = 1. In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for. If you just want to know the MAC address of the adapter currently in use, you can (in Windows 7): Right-click the connection icon in the system tray. Click on the Start Menu, and in the Search box, type cmd then press Enter.

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). All devices with Ethernet cards have MAC addresses, and certain programs or networks require.

Bit 1 (receiver): The first bit of the MAC address specifies whether it is an individual or group address. A Media Access Control (MAC) address is used to guide packets of data to the right point in a network.

The bit sequence of each MAC address is divided into 4 areas, each of which encodes different information.
