How can I find my computers physical address (Mac address)?

· Linux

- On Linux systems, the ethernet device is typically called eth0.

- In order to find the MAC address of the ethernet device, you must first become root, through the use of su. Then, type ifconfig -a and look up the relevant info.

- For example:

# ifconfig -a

eth0 Link encap:Ethernet HWaddr 00:60:08:C4:99:AA

inet addr:131.225.84.67 Bcast:131.225.87.255 Mask:255.255.248.0

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:15647904 errors:0 dropped:0 overruns:0

TX packets:69559 errors:0 dropped:0 overruns:0

Interrupt:10 Base address:0x300

- The MAC address is the HWaddr listed on the first line. In the case of this machine, it is 00:60:08:C4:99:AA.

· Windows 95

- If you have TCP/IP installed, run winipcfg (click Start, then Run, then type winipcfg in the text box.)

- Once the program runs, look for a box marked Adapter Address. This is your MAC address.

· Windows NT

- If you have TCP/IP installed, run ipconfig /all from an MS-DOS shell window.

· Windows XP/2000

- The 12-digit Physical Address is the same as MAC address

- Note that you will need to register all MAC addresses in cases where you have both wired and wireless interface in your system.

· Windows Vista

- From the start menu, enter Cmd in the search window. The Command Prompt Application will appear in the Results Pane. Double click it to launch the application.

- Type in the command ipconfig /all (note the space) and enter. You should see something similar to the following.

- Note that you need the MAC address of your Ethernet card, not your wireless card.

· Mac OS X

- Open 'System Preferences' (usually found in the Dock) and select Network.

- Pick a location and specify the interface whose MAC address is desired in the Show: drop down list.

- For 'Built-in Ethernet', select the Ethernet tab. Read the MAC address labeled 'Ethernet ID:'.
