Out of curiosity, does using CloudFlare WARP 1.1.1.1 hide my traffic from the router and network admin? I’m asking because my internet is shared with other roommates. Can others see the websites I visit?
It does hide it from the router yes. A secure tunnel will be created between your device running WARP and CloudFlare’s servers. Even DNS resolution will happen through this tunnel.
The only thing your Router will see is that you’re connected to a Cloudflare IP and transferring data with it, your roommates won’t be able to view what that data is due to it being encrypted.
