Finding your hardware ethernet address: Windows Vista/7

To determine your hardware Ethernet address:

  1. Click the Windows Start button (the Windows button in the lower left corner of your screen). Type cmd in the "Start Search" field and hit enter.
  2. At the C:\ command prompt, type getmac /v. Your network adapters will be displayed, including the twelve-digit physical address for the Local Area Connection, which is your Ethernet adapter's address.

    If you have a wireless network adapter and wish to use it, the physical address for the wireless network adapter is also displayed. You can tell the wireless apart from the wired hardware address by a "Wireless" or "802.11" label in either the "Connection Name" or "Network Adapter" fields. You will need to enter these numbers (without punctuation) into the automated registration system. If it says "Wireless Disabled", please enable your wireless adapter (often a switch on the outside of a laptop case or a key combination) and run getmac /v again.
  3. When you have finished viewing the hardware addresses, type exit at the C:\ prompt to close the window.
