Everything you need to know about DNS leaks and our testing tool
A DNS leak occurs when your device sends DNS queries outside of your VPN tunnel, potentially exposing your browsing activity to your ISP or other third parties. This happens when your system bypasses the VPN's DNS servers and uses your default DNS settings instead.
Our test queries multiple specially configured DNS servers and analyzes the responses to determine which DNS servers are handling your requests. We then compare this against your expected VPN or proxy DNS servers to detect any leaks.
If a leak is detected, try reconnecting to your VPN, changing VPN servers, or manually configuring your DNS settings to use your VPN provider's DNS servers. You can also enable DNS leak protection in your VPN client if available.
Yes, our test works with all VPN providers and proxy services. The test is provider-agnostic and focuses on detecting whether DNS queries are leaking outside your protected tunnel, regardless of which service you're using.
We recommend testing whenever you connect to a new VPN server, change VPN providers, or experience connectivity issues. Regular monthly checks are also a good practice to ensure ongoing protection.
No, we don't store any personal information, IP addresses, or test results. All testing is performed locally in your browser, and no data is transmitted to our servers or third parties.
Yes, you can run the test without a VPN to see your default DNS configuration. This helps you understand your baseline DNS setup and identify which servers your ISP assigns by default.
