Straight talk about your data.

We use two cookies, both essential:

  • _csrf — Prevents cross-site request forgery. Required for form submissions. Security-only.
  • _dns_session — Only exists if you choose to sign in. No account required to use DNS Tool.

We log your IP address for two reasons: rate limiting (so nobody abuses the service) and security (identifying malicious actors and complying with legal obligations). We check source geography for analysis accuracy — DNS responses vary by region, and knowing which resolver answered from where makes the science better.

No tracking cookies. No analytics cookies. No ad networks. No data brokers. Our code is open-core — the application framework is publicly available under BUSL-1.1 with timed Apache-2.0 conversion. Verify it yourself.

Public analyses are archived by a third party. When a scan is not marked private or run as /dev/null, its report URL is submitted to the Internet Archive, which creates a permanent public record outside our control. That is deliberate — it gives every published analysis tamper-evident provenance independent of us — but it is not reversible, so it is stated here before you scan rather than after.

If you create an account and want out, account deletion removes your login and scan history. Public domain analyses remain available because they contain only public DNS records, already hashed. Full details: Privacy Policy.

Running Real-Time Scan Telemetry

Most scans complete in less than one minute. Some may take longer.

Markers represent known resolver locations. Anycast routing selects the nearest node — exact routing is internal to each provider.

Pipeline nodes reflect live data as each analysis phase completes.
