Bypass School Restrictions Using Custom DNS Settings

Recently I found out students at my school were accessing Discord, on their school Chromebook at home. Not using a Proxy or VPN. Some told me that it was a custom DNS setting that could bypass everything when your’re at home. When they provided me with the DNS settings and tried it for myself on my school Chromebook it didn’t work. This was weird at first because students have shown me actual evidence that this does work on a home WiFi (The schools WiFi blocks you from changing the DNS settings). I’ve done multiple research and it turns out this does work. I will provide the specific DNS setting below so you can try it for yourself.
