ipapi.is
Commercial API, anonymous tierGeolocation, ASN, organisation, and the hosting, datacenter, VPN, proxy, Tor, mobile and abuse classifications.
Used through its public anonymous API only. No database from the project repository is bundled.
Data sources and licences
Every value this product shows comes from one of the sources below, from your own browser, or from a measurement taken against this server. Nothing is inferred, and where a source has no answer the result is reported as Unknown.
Third-party sources
IPinfo
Attribution 4.0 International (CC BY 4.0)Geolocation, ASN, organisation and privacy flags. Only active when this deployment is configured with an IPinfo token.
Optional. The product works without it, and it is never required for a check to run.
Cloudflare
Edge metadataThe public address and country observed at the edge, when this site is served through Cloudflare.
Edge-provided metadata only. No Cloudflare database is used.
ThumbmarkJS
MITBrowser fingerprint component collection, computed entirely in your browser.
Configured with logging and API calls disabled, so no component is ever transmitted.
BotD
MITAutomation indicators.
Loaded with telemetry disabled, so no monitoring request is made.
What is deliberately not bundled
No IP geolocation database is distributed with this product. Commercial and share-alike datasets were reviewed and excluded; the reasoning is recorded in the repository's licence audit. Where a data source is used, it is queried over the network at the moment of the lookup and its terms are honoured.
All tools
- Check Your InternetSee your public IP, browser environment, privacy exposure and network health. Everything runs in your browser. No account, no fingerprint upload.
- What Is My IP Address?See your public IPv4 or IPv6 address, its country, region and network operator, and how data providers classify it. Runs in your browser.
- Browser CheckSee your browser version, operating system, display resolution, device pixel ratio, and whether WebGL, WebGPU and WebRTC are available.
- Browser Fingerprint TestSee the individual signals a browser exposes — canvas, audio, fonts, graphics and more — and how stable they are. Computed locally, never uploaded.
- Internet Speed TestMeasure your download and upload throughput, latency and jitter against this server. Starts only when you press the button.
- IPv6 TestCheck whether your connection reaches this server over IPv6 or IPv4, and see the address family and address that were actually observed.
- WebRTC Leak TestSee which addresses WebRTC exposes to a page, whether they match your public IP, and whether your browser is hiding them behind mDNS.
