Find IP, MAC and Other Network Information on your Apple Mac

Locate the Internet Protocol (IP) address, Media Access Control (MAC) address, and other network information on your Apple Mac computer. This information is used by the Office of Technology Services to support users experiencing network problems.  MAC addresses will be listed in the form of a1:b2:c3:d4:e5:f6, and they contain numbers and letters A through F.  IP addresses (including DNS addresses) will be four sets of numbers between one and 254 separated by periods (e.g. 10.24.34.56).  Using the IP address, you can find information about the network, in this article.
