Omada DNS

Omada is a community and small group of people working on hosting free and open source services on the basis of freedom, privacy and decentralization. One of these services is Omada DNS, which breaks Lightspeed, Securly, GoGuardian and more from working simply using a network setting. This also breaks ChromeOS updates.

If your school has “Managed networks” on, use caudns

Guide

  1. Go to “settings” → “Wi-Fi” → “Known Networks”
  2. Select a network
  3. Dropdown the “Network” option
  4. Click “Name servers” → “Custom name servers”
  5. Set the first field to 66.23.198.252, the second field to 66.94.105.229, the third field to 0.0.0.0, and the fourth to 0.0.0.0
  6. Repeat steps 3-5 on all other networks
  7. Restart your Chromebook to clear cached blocked websites

Issues

Lightspeed keeps a cache for two weeks of blocked websites. Simply use the DNS for more than two weeks.

This does NOT work on filters such as ContentKeeper, iboss, most Cisco configurations, or Fortiguard. They are network level.

If you’re already using OmadaDNS, continue to do so, and DO NOT connect to a Wi-Fi network without it, unless your extensions may update and be patched.

This commonly breaks locked mode quizzes. To fix them: revert the DNS → reboot your Chromebook → go to chrome://policy and press “refresh policies”. If that does not work, then disable DNS → remove user → add user back.
