Terms of Use

Using the tools

ProbeDNS provides free diagnostic tools. You may use them for lawful purposes, including commercial troubleshooting, without an account and without charge.

Acceptable use

Do not use these tools to:

• Probe, scan, or test systems you do not own or are not authorised to assess.
• Generate load that degrades this service or any third party — automated or scripted use that circumvents the published rate limits is not permitted.
• Collect data for spam, harassment, or any unlawful purpose.
• Republish results in a way that presents them as authoritative certification of anything.

Requests are rate limited per IP address. Persistent abuse may be blocked without notice.

Accuracy and limitations

Results reflect what public DNS resolvers, registries, blocklists, and the hosts you name returned at the moment of your query. DNS is a distributed, cached system: two checks seconds apart can legitimately differ. Third-party sources can be stale, rate limited, or temporarily unavailable.

We work hard to report exactly what we observe and to distinguish “not found” from “could not determine”. Even so, these tools are diagnostic aids, not guarantees. Verify anything critical independently — every tool page shows the equivalent command-line check for exactly that reason.

No warranty

The service is provided “as is”, without warranties of any kind, express or implied, including fitness for a particular purpose and uninterrupted availability. We may change, suspend, or discontinue any part of it at any time.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential loss arising from use of, or inability to use, these tools — including decisions made on the basis of a result.

Third-party links and advertising

Pages may link to third-party resources and may display advertising. We do not control and are not responsible for third-party content.
