What is my IP address?
Your public address for IPv4 and IPv6, the reverse name registered for it, and what your device sends with every request. Shown, not stored.

For those responsible for a company connection: we check, on your instruction, which services of your site are reachable from the internet and document the findings. We do not offer this for private connections.
This page stores nothing and sends nothing to third parties. It only shows what your device sends anyway to receive this page.
What these details mean
- Public IP address
- The address under which your connection appears on the internet. Every server you visit sees it – it is not a secret. For a company it is still an identifier: automated scans work through whole address ranges and remember what they find.
- Reverse DNS name
- The name your provider has registered for the address. On business lines it often contains the company itself – which marks the connection as a business line to an attacker and makes it more interesting than a random consumer line.
- Browser and operating system
- Your device sends both with every request so the page renders correctly. Why it matters: an outdated version tells an attacker which known vulnerabilities might be open on your side.
- What is NOT checked here
- We do not scan your connection. Checking which doors are open on someone else's connection is access to a third-party system – we do that only on written instruction, never casually on a tools page.
Frequently asked questions
Why do I see two addresses, IPv4 and IPv6?
Because most connections today have both. Your browser uses one of them for this page (marked CONNECTED); the other is looked up separately. Websites that only speak IPv4 see only that address, which is why your 'IP' can differ between tools.
Is my IP address personal data?
In the EU, yes – courts treat it as personal data because the provider can link it to a subscriber. That is why this page stores nothing and sends nothing to third parties; it only shows what your device sends anyway to receive the page.
Does my IP reveal my exact location?
No. It reveals the provider and roughly the region where the address block is used – a city at best, often just a country. Street-level claims from IP geolocation are guesses.
How do I hide my IP address?
A VPN or proxy replaces it with the exit server's address; the server you visit then sees that one. Your provider still sees you. For companies the question is usually the reverse: which services are reachable at your address from outside – that is what an external attack surface audit answers.
