The fine print, in plain English.

By using Network Lookup, you agree to these terms. We've written them to be readable — if anything is unclear, the contact page is the right place to ask. The "last updated" date at the bottom of this page reflects the most recent revision.

Use at your own risk

The information shown on Network Lookup — IP geolocation, DNS records, ASN data, WHOIS output — is provided as-is. We make a genuine effort to use accurate sources, but data can be stale, incomplete, or wrong:

• Geolocation is an estimate. City-level accuracy is roughly 50–70%, and anything more granular than that is essentially a guess. Don't use a Network Lookup geolocation result as evidence of someone's physical location.
• DNS records reflect what our resolvers returned at the moment of query. Propagation delays and caching mean results may lag behind recent changes.
• WHOIS data is often redacted by privacy services or outdated in registrar databases.

Don't rely on Network Lookup as your only source for security-critical decisions. Cross-check with authoritative sources — the relevant RIR, your DNS provider's management panel, the certificate authority — before acting on anything important.

Acceptable use

These tools exist for legitimate network and security research: understanding your own infrastructure, investigating routing, learning how the internet works. Things that are not acceptable:

• Automated bulk scraping. Don't send automated queries at volume to scrape results. If you have a legitimate use case that requires bulk data, contact us — we may be able to point you toward the underlying data sources or discuss API access.
• Facilitating illegal activity. Don't use these tools as part of unauthorized network reconnaissance, stalking, harassment, or any other illegal activity. "I found the IP on Network Lookup" is not a defence.
• Attacking the infrastructure. Don't attempt to overload, exploit, or interfere with the service. This is obvious, but worth stating.

Rate limiting

We may rate-limit or temporarily block access from IP addresses that generate unusual traffic volumes. This is handled automatically and is not personal. If you believe you've been incorrectly blocked — for example, you're behind a shared IP — use the contact page and we'll look into it.

Intellectual property

The Network Lookup interface, design system, written content, and original code are owned by Network Lookup. You may not reproduce the site design or content at scale without permission.

The data displayed by the tools — IP registry records, routing data, DNS records, WHOIS information — comes from third-party public sources and remains the property of those sources. We're a viewer and display layer, not the source of record. The relevant registries (ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC), DNS operators, and certificate authorities hold the authoritative copies.

No warranties

We provide Network Lookup without warranty of any kind. We don't guarantee that the data is accurate, that the site will be available at any given moment, or that any particular tool will work correctly for your specific use case. If the site is down or a result is wrong, we genuinely want to know — but we can't be held liable for decisions made on the basis of that information.

Limitation of liability

To the extent permitted by applicable law, Network Lookup and its operators are not liable for any damages arising from the use of — or inability to use — these tools. This includes damages from relying on inaccurate data, disruptions to tool availability, or any other failure of the service. The tools are provided for informational purposes; you bear responsibility for how you use the information they provide.

Changes to these terms

We may update these terms as the service grows — when new tools are added, when legal requirements change, or when we learn something needs to be clearer. Continued use of the site after changes are posted constitutes acceptance of the updated terms. The "last updated" date below tells you when the current version was published.

Governing law

These terms are governed by the laws of the State of California, United States, without regard to its conflict of laws principles. Any dispute arising from these terms or your use of Network Lookup will be resolved in the state or federal courts located in California.
