Terms of Use

Last updated: November 10, 2026

By using itoolkit you agree to these terms. If you do not agree, please do not use the website.

The service

itoolkit provides free online tools to look up public network information: IP addresses, DNS records, domain registration data, and SPF and DMARC records. The service is provided free of charge and may change or stop at any time.

Acceptable use

• Use the tools manually and for legitimate purposes: administration, troubleshooting, security and research.
• Do not use scripts, bots or scrapers to send automated requests, and do not try to get around the rate limits.
• Do not use the tools to harass anyone or to plan attacks against networks or systems.

We may block access from IPs or networks that abuse the service.

No warranty

Results come from third-party sources (DNS servers, domain registries and geolocation databases) and may be incomplete, outdated or wrong. IP geolocation in particular is approximate. The tools are provided "as is", without warranties of any kind. Always verify important information with the authoritative source before making decisions.

Limitation of liability

To the extent permitted by law, we are not liable for any damages arising from the use of, or inability to use, the website or its results.

Third-party data

IP geolocation data is provided by DB-IP under the Creative Commons Attribution 4.0 International License.

Law

These terms are governed by Spanish law.
