What Is My IP Address?
See your public IP address instantly, plus your ISP, AS number, approximate location and connection details. Free, no tracking, IPv4 and IPv6.
Your public IP, and what it reveals
Your public IP address is the address the internet sees when you connect — the one every website you visit receives automatically. It's assigned by your internet provider, not by your device, and it's how return traffic finds its way back to you.
Alongside it we show the network that address belongs to: the ISP, its AS number, the approximate location the address is registered to, and which Cloudflare edge served your request.
Public vs private IP addresses
The address shown here is your public one. The address your computer reports internally — usually something starting 192.168. or 10. — is a private address that only exists inside your own network, and it's invisible to the internet. Your router translates between the two, which is why every device in your home shares one public address.
Private ranges are reserved by RFC 1918 precisely so they can be reused in every network on earth without colliding. You can check whether any address is public or private with the subnet calculator.
About that location
Geolocation comes from who the address block is registered to, not from your device. There's no GPS involved and no permission prompt, which is exactly why it's approximate: usually right about the city or metro area, frequently wrong about the neighbourhood, and occasionally wrong by a whole region when an ISP routes traffic through a distant hub.
If you're on a VPN or corporate proxy, everything shown describes the exit node — that's the point of a VPN.
FAQ
Why does my IP address keep changing?
Most residential connections get a dynamic address that can change when your router reconnects or your ISP's lease expires. A static address that never changes is usually a business option. Either way it's your ISP's choice, not a setting on your device.
Why do I see an IPv6 address instead of IPv4?
Because your connection supports IPv6 and preferred it. That's a good sign — IPv6 is the current version of the protocol and avoids the address exhaustion that made IPv4 addresses scarce. Many networks run both; which one you see depends on which was used for this request.
Can someone find my home address from my IP?
No. The mapping goes to your ISP's registered location, not your door. Only your ISP knows which subscriber had an address at a given time, and they hand that over on a legal request, not casually.
Is it dangerous for a website to know my IP?
Every site you visit necessarily learns it — the connection can't work otherwise. It's identifying in the sense that it's often stable for a while, which is why it's used for rate limiting and fraud detection, but on its own it names a network, not a person.
How do I find who owns an IP address?
Use the WHOIS lookup with an IP address or AS number. It queries the regional internet registry (ARIN, RIPE, APNIC and friends) and returns the allocated block, the organisation, and the abuse contact.
