Not sure if your DNS is leaking? Find out in seconds.
A DNS leak occurs when your DNS queries are sent to your Internet Service Provider's DNS servers instead of through your VPN's encrypted tunnel. This means your ISP — and potentially anyone monitoring your connection — can see which websites you visit, even when you think you're protected by a VPN.
How Does DNS Work?
Every time you visit a website, your device sends a DNS (Domain Name System) request to translate the domain name (like google.com) into an IP address. Normally, these requests go through your ISP's servers, which means your ISP can log every website you visit.
Why Are DNS Leaks Dangerous?
- Your ISP can see and log every site you visit
- Your browsing history can be sold to advertisers
- Government agencies can request your browsing data
- Your real location can be exposed even with a VPN
