AUTO CHECKS

Not run

Secure DNS reachability

Compare public DNS-over-HTTPS response times. This does not identify your device’s configured resolver.

Not run

IPv6 availability

Check whether this browser can reach an IPv6 address endpoint.

Optional

WebRTC address exposure

A direct browser test can reveal addresses available to WebRTC. Contacts Google’s public STUN service.

Local only

Browser environment

Public IP profile

Reported address ownership and network registration.

IPWHO.IS

This lookup does not verify residential use, “native” status, cleanliness, reputation, or eligibility on any platform.

AI website connectivity

Automatic, best-effort browser network checks.

AUTO

A completed request only indicates a basic network path from this browser. Cross-origin rules hide the HTTP response; this does not test sign-in, API access, account eligibility, or platform risk decisions.

A more transparent way to test.

✓No login, cookies for tracking, or report history.
✓Browser details are read locally and are not uploaded to NetCheck Atlas.
✓Automatic checks contact ipwho.is, public DNS endpoints, an IPv6 endpoint and Google STUN. Browser details stay on this device.

On page load, this site contacts ipwho.is for IP details, Google and Cloudflare DNS-over-HTTPS, ipify for IPv6, Google STUN for WebRTC, and chatgpt.com, claude.ai, and gemini.google.com for basic connectivity checks. These services receive network requests and may process request metadata under their own policies. Detailed browser diagnostic values are read locally and are not included in analytics. Cloudflare Web Analytics collects page-visit and performance statistics; its service receives usage and request metadata.

Useful signals, without pretending they tell the whole story.

An IP lookup can estimate a network’s location and provider. It cannot reliably prove that an address is “clean,” residential, or safe for a particular account.

This first version intentionally avoids a black-box risk score. Results are informational, may be approximate, and can differ between databases and networks.

Want to compare connection behavior? Run the DNS checks above and compare the round-trip times from this browser. Results are browser-to-provider timings, not a global ping test.
