Overview

Check your connection for DNS leaks

See which DNS resolvers answer your browser’s requests. Choose a standard 6-query check or an extended 18-query test to view each resolver’s IP, provider, ASN, country, and type.

Choose a mode and start the test. No signup required.

The test on this page sends DNS queries from your browser and reports which resolvers answer, including their IP address, provider, ASN, country, and resolver type. Compare these results with the DNS resolver expected for your VPN, proxy, browser, or network configuration.

Seeing a resolver operated by your real ISP Premium can indicate a DNS leak. However, an unfamiliar provider or a resolver in another country does not prove a leak by itself, especially when public DNS services are used.

Designed for the job

Use the result, then tune the route

Run the check, note what it exposes, and use the result to decide whether the proxy, browser, or DNS configuration needs adjustment.

Run

Use the tool with the exact proxy or browser configuration you want to evaluate.

Interpret

Separate a network finding from a browser, DNS, or destination-specific behavior.

Adjust

Change one variable at a time, then run the check again to verify the improvement.

Deep dive

What is a DNS leak?

Proxy DNS leaks depend mainly on how your browser, application, or automation tool resolves hostnames.

Some clients resolve domains locally, while others pass them to the proxy for remote resolution

A DNS leak happens when DNS requests bypass the VPN or proxy route you intended to use.

It is usually caused by browser, application, operating-system, or tunnel settings

Workflow

Do proxies leak DNS?

01 · Run the diagnostic

Run the diagnostic with the intended setup.

02 · Read the signal

Read the signal the tool actually measured.

03 · Check the environment

Check whether browser, proxy, or DNS context changes it.

04 · Change one variable

Change one variable at a time.

05 · Run it again

Run the test again to verify the result.

06 · Keep the verified setup

Keep the verified setup available for later checks.

Details

What causes a DNS leak

Run the check against a known route, read the result, and adjust the setup only when the evidence points to a change.

Keep credentials private and use the support channel when the result is unclear.

Practical guidance

Interpret the result carefully

A diagnostic is a decision aid. It should tell you what to investigate next, not promise a universal answer.

Signal

Identify what the tool actually measured.

Context

Compare it with the browser, proxy, and destination setup.

Make one controlled change and test again.

FAQ

FAQs

Yes. Pick residential, mobile, or ISP Premium based on risk and session needs, then point your tool at the proxy host from the dashboard.

Residential and mobile use per-GB packages (billed monthly or pay as you go). ISP Premium is priced per IP. There are no free unlimited plans.

HTTPS works for most browser and scraper stacks. SOCKS5 is available when your tool prefers it.

Yes on eligible products. Hold the same IP for multi-step flows, or rotate per request for bulk collection.
