Yes, quad9 is a DNS provider, meaning the way to configure quad9 as your DNS provider is the same as configuring cloudflare but instead of 1.1.1.1 it’s 9.9.9.9 (hence the name quad9)

edit: if you’re using android or a browser (or really anything that uses DNS over https), the URLs are different, but you can find more info at https://quad9.net/

I use duckduckgo on Firefox and mullvad browser, I also use it on my phones, but in my ungoogled chromium I’m trying out startpage.

Yeah, I literally got locked out for “suspicious behavior” (me changing from gmail to protonmail and being more active on the platform) and then it said for me to change the password and reddit wouldn’t allow me to. I fucking hate reddit.

They’re anti-profit lol
