    You can also use the, “About this Mac,” feature in the Apple menu. Click on more info and then on the Network category on the left side of the window. All network information will be displayed.

    I use the widget located at http://www.apple.com/downloads/dashboard/networking_security/ipwidget.html. It’s fast and simple.
