Check if your DNS queries are leaking outside your VPN or secure DNS tunnel. A DNS leak can expose your browsing activity to your ISP.
Click the button below to check which DNS servers are handling your queries.
A DNS leak occurs when your DNS queries are sent to servers outside your VPN or secure DNS configuration. This can happen even when you're connected to a VPN, exposing which websites you visit to your ISP or network operator.
Your ISP can see every website you visit, even with a VPN. Your browsing history is exposed.
All DNS queries go through your VPN or secure DNS. Your ISP cannot see which sites you visit.
Enable DoH in your browser or system settings. This encrypts DNS queries and sends them over HTTPS, preventing leaks.
Ensure your VPN is set to use its own DNS servers. Most VPN apps have a "DNS leak protection" setting.
Switch to a privacy-focused DNS like Cloudflare (1.1.1.1), Quad9, or Mullvad DNS. These don't log your queries.
WebRTC can leak your real IP. Use a browser extension to disable it or use a VPN with WebRTC leak protection.
