OpenDNS FAQ

What is OpenDNS?

OpenDNS is a company that provides cloud-delivered network security services that protect devices from known and emergent threats such as malware, spyware, adware and phishing sites. The OpenDNS service uses up-to-the-minute analysis of 2% of the world’s Internet activity to stay ahead of attacks. This predictive intelligence is enforced in the cloud, blocking access to domains or IP addresses that post a threat.

David Ulevitch, OpenDNS Founder & CEO, is a graduate of Washington University in St. Louis.

Who will use it at WUSTL?

OpenDNS will be available for everyone who accesses the Internet via the Washington University DNS servers by default.

How does it work?

When a user on the Washington University network tries to access a webpage that OpenDNS has identified as a known or emergent threat, OpenDNS will redirect the user to an alert page on the Washington University Information Security website that provides information and/or instructions on how to proceed.

OpenDNS is blocking a legitimate domain. What should I do?

If you find that OpenDNS is blocking a legitimate domain, contact the Washington University Information Security Office at infosec@wustl.edu.

I am traveling, how can OpenDNS protect my device from malware?

Washington University students, faculty and staff can take advantage of the OpenDNS protection service while traveling by downloading the Washington University OpenDNS client. It will run in the background of your device, and provide the same level of protection available on campus.

Can I use this protection at home?

Washington University students, faculty and staff who would like to take advantage of the OpenDNS protection service at home have two options.

  1. Users can download the free OpenDNS Home service for personal use. This service provides Web content filtering and phishing protection but does not block malicious domains.
  2. Users can contact the Information Security Office to get the OpenDNS client at infosec@wustl.edu.
