All OS [Tip]Turn off WhatsApp without turning off the internet

Proxy and dns are different.

Also just point to a local address that your router handles. 192.168.x.x in most cases. And then reserve that address to random MAC address so that dhcp doesn’t assign it.

This will work for both mobile data and wifi.
His question was, what if the ip address resolves to some random chinese isp or ip address. And that was my answer.
I know proxy and dns are different but you know even a proxy has its own dns server to resolve internet queries? If I have a proxy with address 10.100.10.100 for example and my proxy has its own dns server at 10.100.10.1, then if someone uses my proxy server to connect to the internet he will get dns queries answered from my server. My proxy will act like a middle man.

Of course I know.

Your answer mentioned setting fake dns which is different than proxy. Just pointing it.
 
I actually tried this today and this works. I set the proxy address to 127.00.1 or something like that. I tried messaging from another phone and I did not receive the message. Every time I sent a message to my phone, I received the "Whatsapp may have received new messages" thing but it did not come through. Thanks for the tip.
