Terms of use & disclaimer

NetChecks is provided for legitimate network diagnostics and educational purposes only, on systems, domains, and IP addresses that you own or are explicitly authorized to test.

Running port scans, DNS/whois lookups, traceroutes, or other checks against third-party systems without authorization may violate computer misuse laws in your jurisdiction (for example the Computer Fraud and Abuse Act in the US, the "Loi Godfrain" in France, or equivalent local legislation). You are solely responsible for ensuring you have the right to test any target you enter here.

This site and its results are provided "as is", without warranty of any kind. The operator of this site accepts no liability for any direct, indirect, or consequential damages, legal consequences, or misuse arising from the use of this site.

Requests are rate-limited to prevent abuse. The operator of this instance may optionally enable request-activity logging - if so, each tool request (your IP address, timestamp, the tool used, and the target/query entered) may be recorded in a database for security, abuse-prevention, and usage-analytics purposes; this is disabled by default. By using this site you agree to these terms; if you do not agree, do not use it.

Programmatic (API) use of this site is subject to these same terms, including the authorization requirement above.
