How do I get my MAC address?

Often times, support will need the MAC address for your computer when it comes to getting an IP on our wired network, as we give IP addresses based off of the MAC address.

For different operating systems, you can get the MAC address through different means.

 For Windows:

  1. Go to 'Start'.
  2. Either go to 'Run' or the 'Search' section for Windows Vista/7/8.
  3. Type 'command' and hit 'Enter'.
  4. In the new window, type 'getmac'.
  5. The MAC Address will be listed under 'Physical Address' section.  Usually in the format of ##-##-##-##-##-##

For Macs:

  1. Go to the Apple icon on your computer (Usually in the upper left hand corner), click on it and select 'System Preferences'.
  2. Go to 'Network'.
  3. On the left side, click on the network connection you will be using.  For wired networks, it will usually be the Thunderbolt Ethernet or the USB Ethernet.
  4. Click on the 'Advanced...' button in the lower right hand corner.
  5. Under this new window, click on the 'Hardware' tab section.
  6. The MAC address will be listed under 'MAC Address' in the format of ##:##:##:##:##:##.

Note: Mac OSX will not show a MAC address for either wired connections unless it is physically connected to an active network connection.  If you still cannot see the MAC address using the Thunderbolt or USB Ethernet adapter, try using a different networking cable, a different Thunderbolt/USB ethernet adapter or another network port.

For Linux/UNIX based computers:

  1. Pull up a terminal session.
  2. type 'ifconfig' and hit enter.
  3. Look for the text 'ether ##:##:##:##:##:##', this entry should be your MAC address for your machine

For Routers:

At this time, due to the numerous types of routers out there, it is wisest to use the Router's Web Interface and look for the WAN (Internet) Setting information for the Router's MAC Address.

Routers have a WAN (Internet) MAC Address, a LAN (Local Area Network) MAC Address and a WLAN (Wirless LAN) MAC Address.  We only need the WAN (Internet) MAC Address.

Wireless Access can only be provided via the Office of Information Technology, as referenced here:
