What is a MAC Address and how to find it

In order to gain access to Hartwick's network services, you may need to provide the MAC address of your computer. Below you will find information on what a MAC address is and how to find it, depending on what operating system you are using (Windows or Mac). If you have any questions, please contact the Technology Resource Center at x4357 or send e-mail to the technology@hartwick.edu.

What is a MAC address:

Your MAC (Media Access Control) address is the network address of the network card within your computer. It is unique--no two are alike and, like your home address, allows us to easily find and monitor your computer on the Hartwick network. The format would be 00-00-5a-99-62-50 or even with colons rather than dashes, such as 00:00:5a:99:62:50.

How to find the MAC address of your computer:

Windows 95/98/ME
• Click on the Start button
• Go to the Run box
• Type "winipcfg" – press Enter
• In the drop-down box where it would say PPP Adapter, change it to the other adapter in the list (just not PPP)
• Once adapter is changed, the Adapter Address is your MAC Address

Windows 2000/XP (Home and Professional)
• Click on the Start button
• Go to the Run box
• Type "cmd" – press Enter
• Type "ipconfig/all"
• Under the "Ethernet adapter Local Area Connection" section, the Physical Address is your MAC address

Macintosh Computer
• Click on the Apple menu icon
• Go to System Preferences
• Under the Network section, click on "Network"
• In the drop-down area, where it says "Show" – choose "built-in Ethernet"
• Click on the Ethernet tab
• The Ethernet ID is your MAC address

If you have any problems or have questions about your MAC address, please call the Technology Resource Center, which is open 9:00 A.M. – 5:00 P.M. Monday thru Friday, x4357 (607-431-4357 if you are calling from a cell phone).
