Request to Block (Whitelist) Off Campus IP

Registered network managers can submit a Security Request form to request a given off-campus IP address be whitelisted.  Include the IP(s) that you need whitelisted, and the reason for the request. If this is a temporary whitelist, please include when the whitelist entry should be removed. Whitelist entries will be processed by the end of business the following day, although requests are often processed much sooner. Whitelist entries may be expedited by calling the 24/7 IT Support Center at (520) 626-TECH (8324). You may also send email to and an UAssist ticket will be opened. You will need to provide the email address from which you sent the security request.
