Every website sees this — automatically
The data above required no cookies, no JavaScript tricks and no permission prompts. Your IP address travels with every single request your device makes, because servers need it to send anything back. That means every website you visit, every image that loads from a CDN, every API call an app makes in the background reveals the same information you see here — to someone else's server instead of your own screen.
From the IP alone, any server can derive roughly what this page derives: your approximate location (usually your city or a neighbouring one), your internet service provider, and the organisation that owns the network — your ISP at home, your employer at the office, your mobile carrier on the go. The lookup happens against a public database; SysLeak hosts that database locally, so your address is never shared with a third-party geolocation service just to answer the question.
What your IP does — and doesn't — reveal
An IP address identifies a network connection point, not a person. It will not give a website your name or your street address. But it is a strong, persistent signal: combined with a browser fingerprint it can re-identify you across visits even with cookies cleared, and your ISP can map it to your account precisely. Geolocation is accurate to the country almost always, and to the city most of the time — close enough to localise prices, content and ads without asking you anything.
If you use a VPN, the address shown above should belong to the VPN provider, not your ISP. That is easy to verify here: check the network organisation row. But hiding your IP is only one layer — your browser fingerprint and WebRTC behaviour can still give you away. The SysLeak exposure dashboard combines all of those signals into a single Exposure Score, so you can see the whole picture instead of a single data point.
Frequently asked questions
- How do websites know my IP address?
- Your IP address is part of every network packet your device sends — without it, the server would have nowhere to send the response. No JavaScript, cookies or permission prompts are involved: every website, image host and API you touch sees it automatically.
- How accurate is IP geolocation?
- Country-level accuracy is typically above 95%, but city-level results can be tens of kilometres off, because the location belongs to your internet provider's infrastructure, not your device. SysLeak uses a locally hosted GeoLite2 database — your IP is never sent to a third-party geolocation API.
- Does a VPN hide my IP address?
- A VPN replaces your visible IP with the VPN server's IP, which hides your network identity from websites. It does not change browser fingerprints, and WebRTC can still leak your underlying addresses — check the SysLeak dashboard to see both.
- Does SysLeak store my IP address?
- No. Your IP is read from the connection, shown back to you on this page, and discarded. It is never written to a database or a log file — see our security documentation for the full data-handling policy.
