Introduction:
Look brother whenever we download a free proxy or virtual private network to hide our identity on the internet we think that we are completely secure. But the actual truth is just the opposite. If you want to know why free VPN apps leak your real DNS server addresses and home locations then you will have to understand the backend server architecture of these apps. Look brother many free apps that are available on Play Store or App Store do not have the resources to maintain proper encryption tunnels. What this simply means is that when you browse your actual DNS request is routed to your local Internet Service Provider and your exact home location is leaked like water.

Look if you Cybersecurity and Infrastructure Security Agency Guidelines Or if you read the official privacy frameworks you will understand how unprotected tunnels expose your real location.
