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 are 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

Go to settings -> Wi-Fi -> Known Networks
Select a network
Dropdown the “Network” option
Click “Name servers -> Custom name servers
Set the first field to 38.175.197.10, the second field to 66.94.105.229, the third field to 167.86.91.171, and the fourth to 0.0.0.0
Repeat steps 3-5 on all other networks
Restart your chromebook to clear cached blocked websites.

Issues

GG is patching this soon with a hardcoded list. Common sites like discord will stay blocked, but you will still be able to use about any proxy link.

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 wifi network without it, unless your extensions may update and be patched.

This commonly breaks locked mode quizes, to fix them revert the DNS then reboot your chromebook and go to chrome://policy and press “refresh policies”
