What is an IP address?
An IP address is the return address the internet uses to send data back to you. When you open a website, your device connects through your internet provider or mobile carrier, which assigns you a public IP. The website sees that public IP — it must, otherwise it could not reply.
IPv4 vs IPv6
IPv4 addresses look like 203.0.113.45 (four number groups). IPv6 addresses are longer, like 2001:db8::1, and were introduced because the world ran out of IPv4 space. Many connections today use both: IPv4 for compatibility, IPv6 where the network supports it. This page shows whichever your network actually used to reach us.
Public vs private IP
Your router gives your phone and laptop private addresses (for example 192.168.1.x) that only work inside your home. Websites never see those. They see your public address, shared by your whole household or assigned per-device on mobile data.
Can websites see my exact location from my IP?
No — not precisely. IP geolocation is approximate: usually correct at city or region level, often wrong on mobile networks and VPNs. We show only the approximate area our IP provider returns, and we say so honestly. Precise location requires GPS permission, which we never request.
Protecting your privacy
Your IP changes over time (dynamic IPs), and VPNs or mobile data give you a different one. Private browsing does not hide your IP. If location privacy matters, review your VPN, carrier and browser settings rather than relying on one toggle.
How it works
Open this page and the embedded script queries only documented browser APIs. Nothing is installed, no account is needed, and results reflect your current browser profile — including extensions, private mode and OS display scaling.
Limitations
Support varies by browser. Privacy features (tracking prevention, user-agent reduction, fingerprint randomization) can generalize or withhold values. Treat results as a best-effort live snapshot rather than a certified hardware inventory.
Privacy
Detection runs in your browser. We do not store fingerprints or device reports. The only network call any tool makes is the optional public-IP lookup on /my-ip (via a third-party IP API, disclosed in the privacy policy).
