How to register your laptop or other personal equipment with our network

If you would to be added to our "trusted" network so that you can use Math Department printers or access the Math Department intranet, you must:

  • Ensure your equipment has all malware removed and is running up-to-date virus/malware protection software. You may purchase your own, or at no cost to you make use of the university-provided automatically-updating Sophos Anti-Virus.
  • Configure your equipment to obtain a network address automatically (via DHCP). Most equipment is configured this way by default.
  • Have us register your network interface MAC addresses (all equipment has these - the term "MAC" does not refer to Macintosh) with our DHCP server. Note that you may have multiple MAC addresses (for example, one for your LAN connection, one for your wireless connection). See below on how to obtain your addresses, then send the information to the computer support staff. (If you are unable to determine the necessary information, then we will be happy to inspect your equipment ourselves. Please contact us to arrange a time.)

Registering for rest of campus

To use personal equipment in areas of campus controlled by UITS, which includes the student union, the campus library, and the ILC, you'll need to register it with UITS. This does not apply to wireless access. There is no registration required for wireless access, but you will need a UA NetID to connect via the UAWiFi connection. UAGuest does not require NetID, but it is not secure and does not allow certain types of connections.

  • Students: you can do this by following the instructions on this page.
  • Faculty, Visitors, and Staff: you must ask us to register your equipment with UITS on your behalf. In your request, include the same MAC address information discussed below.

How to obtain your MAC addresses:

Microsoft Windows

Open a DOS prompt and use the command ipconfig /all. As in the screenshot below, look forPhysical Address on your LAN and/or wireless adapter, but ignore the PPP (dial-up) adapter if there is one.


Use the command ifconfig or /sbin/ifconfig. As in the screenshot below, look for HWaddr on your LAN (often eth0 or en0) and/or wireless (often wlan0 or ath0) adapter.

Mac OS X

Go to the Apple Menu and choose About This Mac:

Click on System Report...

Choose Network on the left, then Ethernet at the top, and find the Ethernet MAC Address below.
