DNS leak

A DNS (Domain Name System) Leak is when your computer accidentally sends out a request for internet information to the wrong server. Sometimes, this request can go to someone other than your internet service provider (ISP). This means that your ISP and other outside companies can know what websites you're visiting, even if you're using a virtual private network (VPN) to stay anonymous online. A DNS Leak can put your online privacy and security at risk. To avoid this, it's important to use a reliable VPN service that offers DNS Leak protection.
