One IP

Terms of use

Service scope

This site provides IP lookups, network diagnostics, browser checks and service status queries.

Acceptable use

Use these tools only for targets you are authorized to test. Do not use the site for unlawful activity, disrupting third-party services, bypassing access restrictions or abusing the API.

API and request limits

The API requires no key but is rate-limited by request IP. Reduce request frequency after a 429 response; do not rotate IPs to bypass limits. Cross-site browser calls are restricted.

Interpreting results

HTTP responses and latency differ from ICMP ping and do not establish AI login, chat or model access. An egress IP describes the route of that request only. IP reputation and browser anomalies alone do not prove abuse or identity spoofing.

Results and availability

Results depend on the network, browser restrictions and third-party data. They are for reference and do not guarantee security, account access or continued availability. Maintenance, rate limits or upstream failures may interrupt service.

Third-party services and open-source license

When visiting third-party links or using their services, follow their terms as well. Use of the source code is governed by the license in the repository.

Service changes

Features, data sources and rate limits may change. Check the current instructions before use and verify important results through the relevant official service.
