What Does the Internet
Actually Know About You?
Every website you visit silently collects your IP address, ISP, city, timezone, and a browser fingerprint that identifies you across sessions — even if you clear cookies. This tool shows you exactly what they see. 100% client-side. Nothing sent to our servers.
How to read the result
What each signal means.
Public IP + ISP
The address every website sees when you connect. Combined with your ISP name, this identifies your internet provider and rough network. If VPN is on, both should belong to your VPN provider — not your home ISP.
Geolocation
City, region, and country derived from your IP. Accurate to the city level about 60-80% of the time. On a VPN, this shows the VPN exit city — not where you actually are.
VPN / Datacenter flag
We compare your ISP against known VPN and datacenter operators. A green flag means your VPN is masking you as expected. No flag on residential IP means every site sees your real ISP.
Browser fingerprint
The combination of user-agent, screen size, languages, timezone, and platform that identifies you uniquely across sessions — even in Incognito. This is what trackers use when your IP changes.
Mask the Signals
Your IP is the biggest signal. Cover it, cover 80% of your exposure.
Every value this tool just showed you is data trackers, ad networks, and data brokers are already collecting. CyberFence VPN replaces your real IP, ISP, and city with our exit node — instantly stripping the largest identifying signal. Bundle with Breach Monitor and Web Shield in CyberFence Complete to close the rest of the gaps.

- ✓ Kill switch blocks all traffic if the tunnel drops (no accidental exposure)
- ✓ Forced-tunnel DNS on every platform — Mac, Windows, iOS, Android
- ✓ No-log policy, US-operated, independently audited

FAQ
Everything you need to know about IP and browser privacy.
What information does this tool reveal about me?+
This is exactly the data any website you visit can silently collect about you: your public IP address, your ISP and ASN, your approximate city/region/country, your timezone, your browser and operating system, your preferred languages, your screen resolution, and whether your browser is set to 'Do Not Track'. Nothing here is a leak — every value on this page is available to every site you visit, every ad network you touch, and every tracker on the page. This tool just shows it back to you.
Is this tool 100% private?+
Yes. Your IP address is looked up client-side via a public, keyless HTTPS API (ipwho.is) that returns geolocation and ISP data. Browser fingerprint data is read directly from your browser and never leaves your device. Nothing on this page is sent to CyberFence servers, nothing is logged, and closing the tab discards everything.
How accurate is IP-based geolocation?+
IP geolocation is accurate to the city level about 60-80% of the time. It uses a database that maps IP ranges to the physical location of the ISP's point-of-presence — which is usually your city, but can be a nearby city or even the ISP's regional data center. It is not GPS-accurate. If you are on a VPN, the reported location is the VPN exit node, not your real location.
What does the VPN/Proxy detection actually check?+
We compare your reported ISP against a heuristic list of known hosting providers, VPN operators, and cloud data centers (AWS, DigitalOcean, OVH, M247, etc.). If your ISP name matches a datacenter pattern, we flag it as 'Likely VPN or Datacenter'. This is a rough signal — sophisticated VPNs can hide behind residential proxies, and some legitimate ISPs sell residential-fiber IPs that look like datacenters. Absence of a flag does not guarantee you are unmasked.
What is a browser fingerprint?+
A browser fingerprint is the combination of user-agent, screen resolution, installed languages, timezone, platform, and dozens of other details that trackers combine to identify you uniquely — even when you clear cookies. Two users on the same VPN with the same IP can still be told apart by their fingerprints. This tool shows you a simplified version so you can see what trackers are seeing.
How do I hide the information this tool shows?+
Different signals need different tools. To hide your IP and geolocation: use a VPN with a real kill switch (CyberFence VPN). To hide your fingerprint: use a hardened browser (Brave, LibreWolf, or Tor Browser) that spoofs the noisy signals. To hide your ISP and DNS trail: use encrypted DNS (DoH or DoT) on top of a VPN. No single tool eliminates every signal, but a VPN closes the biggest and easiest one — the IP address itself.
