Terms of Service
Last updated: October 21, 2026
The service
MXDoctor provides free, automated diagnostic lookups of publicly available information (DNS records, certificates, blacklist status, HTTP responses) about domains and IP addresses. Results are generated live at the moment of the check and reflect the state of public data at that moment.
No warranty of results
DNS data changes constantly and propagation means different observers can legitimately see different answers at the same time. Results are provided "as is", for general informational purposes, without warranty of accuracy, completeness or fitness for a particular purpose. Always verify consequential changes with your DNS or hosting provider. MXDoctor is not liable for decisions taken on the basis of a check result.
Acceptable use
Use the tools at human scale. Automated scraping, bulk querying, or any use designed to degrade the service for others is prohibited and may be blocked without notice. Checks may only target domains and addresses you own, administer, or have a legitimate diagnostic reason to inspect.
Intellectual property
The site's content, design and code are the property of MXDoctor's operators. The DNS records, certificates and other public data displayed in results belong to their respective owners.
Changes
We may update these terms; continued use of the site after a change constitutes acceptance. Material changes will be noted on this page with a revised date.
