NLZIET runs on Cloudflare. On NLZIET's own domain, /cdn-cgi/trace returns the country a visit comes from, and other pages can read it. That's the location NLZIET itself sees, and the page checks it against NLZIET's list of supported countries.
Each service locates IPs with its own database, and they don't always agree: the same proxy can be in Japan for one service and in Hong Kong for another. Some services also turn away data center IPs and known VPNs. The country shown is the one NLZIET itself sees. Try another server; a home broadband IP usually gets through more often.
Proxy apps (Clash, Surge, Shadowrocket and others) can send different sites over different routes. A script on a server can only test that server's IP. This page visits each service from your browser, over the route you actually use for it.
They show how reliable a result is, most reliable first. Official API: the service's own region API says whether it works. Official location: the service's servers say which country they think you're in, checked against the countries it supports. Redirect test: whether the service sent you to its "not available" page. Guess: the service lets nothing be read, so the page only knows it opens and uses the country other services see.
Your proxy rules may send them through different servers (split routing), or the services use different IP databases. When that happens, the page lists which services see which country. To make them agree, route these services through the same server.
AI services compare your browser's time zone with your IP's country. A time zone in China with an IP in the US looks like a proxy and can trigger extra checks. Setting your device's time zone to match your IP helps.
Not while testing. Your browser contacts each service directly; this site only serves the page and never sees your results. When you share on 1ms.dog, the short link and its preview image are stored there so chat apps can show them; shared results don't include IPs. Use Hide IPs before taking a screenshot.
