What are DNS Leaks?

DNS (Domain Name System) leaks are a type of security issue that can occur when using a virtual private network (VPN) to access the internet. When you visit a website, your device sends a request to a DNS server to translate the domain name into an IP address. This translation process is necessary for your device to connect to the website's server and load the content.

However, if your device is configured to use a DNS server outside of your VPN's secure network, your DNS requests will bypass the VPN and go to the DNS server provided by your Internet Service Provider (ISP). This can potentially expose your true IP address to your ISP or any other third-party monitoring your internet traffic.

DNS leaks can happen due to several reasons such as:

Improper VPN configuration: If your VPN is not properly configured to route DNS requests through its own DNS servers, the requests may leak outside the VPN tunnel.

Malware or DNS hijacking: Malware or malicious actors can manipulate your device's DNS settings to redirect traffic to their own servers, bypassing the VPN tunnel.

Operating system or software vulnerabilities: Certain vulnerabilities in your operating system or software can allow DNS requests to bypass your VPN, resulting in DNS leaks.

DNS leaks can compromise your online privacy and anonymity, as well as bypass any geolocation restrictions set by your VPN. To prevent DNS leaks, it is important to use a VPN that properly routes your DNS requests through its own DNS servers, and regularly test for DNS leaks using tools like DNS leak test.
