What is DNS leak? Why it matters?
A DNS leak happens when your domain name requests are sent through your internet service provider instead of being routed through your VPN. It exposes your IP address to the websites you visit, even if your IP address appears masked.
DNS requests translate domain names into IP addresses. If these requests are not properly secured, they can reveal browsing activity and reduce the effectiveness of your connection setup.
How a VPN prevents DNS leaks?
A VPN helps prevent DNS leaks by routing all your requests, including DNS requests, through its own secure servers instead of your ISP. Therefore a VPN ensures that your browsing activity is handled within the VPN network rather than exposed externally.
Some VPN solutions like 1click VPN include built-in DNS leak protection that forces all requests through the encrypted tunnel, helping maintain consistent protection while you browse.
How DNS Works in Your Internet Connection
When you enter a website address, your device sends a DNS request to find the correct IP address of that site.
The DNS server processes the request and matches the domain name with its corresponding IP address.
Using the returned IP address, your browser connects to the website’s server and loads the page.
