Understanding DNS Leaks and How to Prevent It

Importance of a VPN

In today’s digital world, data security plays a key role. However, even with encryption and other security measures in place, DNS leaks remain a serious threat. DNS (Domain Name System) is a system that provides the conversion of domain names into IP addresses necessary to establish connections between devices on the Internet. A DNS leak occurs when DNS queries are sent over an inappropriate channel, often without encryption, allowing attackers to access sensitive information.

How Does a DNS Leak Happen?

A DNS leak can happen for a variety of reasons. One of the most common is the use of unencrypted connections to DNS servers. When you use a VPN or proxy to hide your real IP address, but don’t configure your system to use secure DNS servers, you run the risk of a DNS leak. This can happen because the operating system continues to send DNS queries through normal channels without paying attention to the VPN settings.

Another reason for a DNS leak could be the use of untrusted programs or browser extensions that can change DNS settings without your consent. This could result in your DNS requests being sent through attacker-controlled servers instead of your ISP’s secure servers.

Consequences of a DNS Leak
