We do not offer phone support. Email lets us look up the details of your case and give you a written answer you can keep.

Report a wrong IP location or ISP

If the IP lookup shows the wrong city, country or ISP for your IP address, email us the IP address, the location shown and the correct location. We check it against our GeoIP sources and correct our data when the source confirms it. Changes in third-party GeoIP databases can take several weeks to appear, because those providers update on their own schedule. If you manage the IP range, also contact your ISP or the regional internet registry, since they publish the records that lookup tools rely on.

Technical support and bug reports

For a tool that fails or returns an error, send us the tool name, the IP address or domain you tested, the time of the test and a screenshot of the result. Tell us your browser and device. With these details we can reproduce most problems on the first try. Feature suggestions and requests for new tools are welcome at the same address.

Privacy requests

To access, correct or delete personal data we hold, or to object to its processing, email [email protected] with the subject "Privacy request". Include the IP address and approximate date of your visit so we can find the related records. We reply within 30 days. The privacy policy lists what we collect and how long we keep it.

Report abuse of our tools

If you see traffic from CheckIP servers scanning or testing your systems without your permission, email us with the subject "Abuse report". Include the target IP address or domain, the time of the traffic in UTC and log lines if you have them. We investigate every abuse report and block users who break our terms of service.

Business and partnership inquiries

For API access above the free limits, data partnerships, advertising or other business proposals, email [email protected] with the subject "Business inquiry". Tell us your company, the volume of requests or the type of cooperation you have in mind, and how to reach you.
