How to Find Your MAC Address
MAC is an acronym for Media Access Control. A MAC address is an address that is given to a network adapter (NIC) that helps a computer to identify it. Since many functions of a computer can be determined by the MAC address on the network adapter, it is important to be able to find your MAC address in case it is requested.
Finding a MAC address is, for the most part, simple. However it depends on which operating system you are using. Here are a few tips on how to find your MAC address when your computer runs certain popular operating systems.
Finding Your MAC Address When Using Windows OSs
Windows NT
If you are running Windows NT, finding your MAC address is quite simple. Run the command ipconfig/all within your MS-DOS shell window. The MAC address will be clearly visible.
Windows 2000 and Windows XP
Open up your command prompt window by clicking Start, then Run, then cmd. Once in the command prompt window, type ipconfig/all and the MAC address will be visible. The 12 digit "Physical Address" is actually the MAC address.
MAC OSx
On your MAC OSx computer, open the system preferences and select Network. Now, you will need to choose an interface. Remember to choose the interface that contains the MAC address you are trying to locate. You can do this by going to Show and then looking in the drop-down list. If you are looking for the MAC address of built in Ethernet cards (NIC), simply select the Ethernet Tab and read the MAC Address which is labeled as "Ethernet ID".
Note: If you have a wireless card, follow the above steps, but instead of selecting the Ethernet card, choose "Air Card". Your MAC address will be labeled as "Air Card ID".
Finding Your MAC Address on a Linux OS
On most Linux systems, the Ethernet device (NIC) is called eth0. To find the MAC address on these devices, first login as the root using the su command. Then simply type the command ifconfig -a. You should see a 12 digit address, usually labeled HWaddr.
