Your public IPv4 address

An IP address (Internet Protocol address) is the number that identifies your device on the internet. Every request you send carries it, so the server knows where to send the answer back. It is a bit like a return address on an envelope: necessary for the mail to work, and visible to everyone who handles it.

Yes. Every website you visit, every app you open and every email server you touch can see it. That is exactly how this page found yours — you did not tell us, your connection did. It is not secret, which is why it is worth knowing what it reveals.

Your approximate location (usually the city or region, not your street), your internet provider, and whether you are on mobile, broadband, a business line, a hosting provider or a VPN. It does not reveal your name, your address or the contents of your traffic. Combined with other data, though, it is a durable way to track you across sites.

IPv4 addresses look like 203.0.113.42 and there are about 4.3 billion of them — long since exhausted. IPv6 addresses look like 2001:db8:85a3::8a2e:370:7334 and there are enough for every grain of sand on Earth, many times over. Most connections today run both at once; your network picks whichever the destination supports.

They are separate addressing systems running side by side on the same connection. Your provider assigns both independently, so there is no relationship between the two numbers. Some networks are IPv4-only and have no IPv6 address at all, which is completely normal.

IP geolocation is an estimate built from provider registration data, not GPS. It typically resolves to your ISP's regional hub rather than your actual neighbourhood, and mobile networks can place you a hundred kilometres away. If you are on a VPN it shows the server's location, which means it is working.

Usually, yes. Most home connections get a dynamic address that changes when your router reconnects or after a lease expires. Static addresses that never change are typically a paid business option. Mobile connections change addresses constantly as you move between towers.

The address on this page is your public IP — the single one your whole household shares with the outside world. Behind your router, each device also has a private IP such as 192.168.1.14 that only exists on your local network. Websites never see the private one.

A VPN is the practical answer: it routes your traffic through an encrypted tunnel and websites see the VPN server's address instead of yours. Tor also works but is far slower. Simply restarting your router may get you a new address from your provider, but it will still point to the same city and the same ISP.

Yes. Looking up your own address, or any address that connects to a server you run, is entirely ordinary — it happens automatically in every web server log on the planet. What matters is what you do with it, and harassment or unauthorised access is illegal regardless of how you obtained the address.

This page reads your IP from the connection, prints it, and that is the end of it. There are no trackers, no advertising scripts, no cookies and no third-party fonts — the entire page is one file served from one server, and your location is looked up here rather than by asking anyone else. The one outbound call is the optional China-route check, which your browser makes directly to speedtest.cn. Standard web server access logs exist, as they do everywhere.

Yes. Run curl https://find-my-ip.com and you get your bare IP address as plain text, ready to pipe into a script. Add /json for a structured response. The page detects terminal clients automatically, so no flags are needed.
