FAQ: How can I find a MAC address?

FAQ L15

The MAC address is also known as the hardware address.

Mac OS X

  1. Select System Preferences... from the Apple menu and choose the Network icon.
  2. In the left hand pane select the interface for which you want to get the MAC address: AirPort for wireless or Ethernet for wired connections and click Advanced...
  3. Choose the Ethernet tab and the MAC address is listed as the Ethernet ID. It will be in the form 0a:1b:2c:3d:4e:5f

Windows

  1. Open the Command prompt. For example, on Windows 7 go to Start, type 'cmd' into the 'Search programs and files' box, then click OK. This will open a command window.
  2. Type ipconfig /all and press Enter.
  3. Find the Physical Address line under the section that lists your network adapter. The MAC address is in the form of six groups of two hexadecimal digits separated by hyphens, e.g. 00-27-0E-11-DA-93

Linux

  1. Open a Command Shell (e.g. xterm, gnome-terminal)
  2. Type /sbin/ifconfig at the shell prompt, then press Enter or Return
  3. You should see a network adapter listing. Most Linux distributions call the first Ethernet adaptor eth0. You will find the MAC address listed after HWaddr, for example:- eth0 Link encap:Ethernet HWaddr 00:04:23:D6:B1:ED
