What Is My IP?
Shows the exact address your device reached this page through — the one every router and online service sees as you — plus its likely location and whether it is a private or public address.
Fill in the values and calculate
The form sends itself back to this page — results print below, computed on the server.
Notes, formula and assumptions
- This address came off the request itself: the first entry of the forwarded-for chain the proxy set, or the local socket when nothing was forwarded.
- Private blocks name loopback and test addresses no network resolves back to a subscriber; a public address belongs to ranges routed to real ones, which is why DNS records, routers and counters identify you by it.
- Live place reading from ipinfo.io: Columbus, Ohio, US at 39.9612, -82.9988 — that names the block your provider routes, not a door.
- Leave the box blank and the page answers about your own connection the moment it loads; type another address in it only to compare that one the same way.
About What Is My IP?
The address shown is the one your connection carried into this page: the server reads the forwarded-for chain its proxy set (a bare local connection has no chain, so the socket that carried the request is named instead). Nothing is guessed from a cookie, a stored value or a guess about your device, and the page answers the moment it loads.
That is your address at the network layer, which is what everything out there sees: your DNS server's records, a router's traffic counter, any account-less identification — they all act on exactly this string. This page itself keeps nothing at all.
A live ipinfo.io reading adds the town and coordinates the address belongs to: IP geolocation names the block your provider routes, so the place is a neighbourhood rather than a door. A private block (10.x, 127.x, 172.16-31, 192.168.x, the 169.64-66 test ranges) names a loopback or test address no network resolves back; the ip-lookup tool takes any dotted quad for the full octet-and-binary reading.
Questions about What Is My IP?
How does this page know my IP?
The server answering your connection hands the request its own chain of forwarding headers, and the first entry of that forwarded-for chain is your device's address; a bare local connection has no chain, so its socket is named instead. The page answers as soon as it loads.
Is it really my address?
It is the address your network presents to the internet, which is what everything beyond it sees. A VPN, a proxy or an in-app browser that pre-fetches pages can put its own address forward instead — that is why two networks can report different answers.
How exact is the shown location?
IP geolocation resolves to the block your provider routes, so the named town is the area your network sits in — accurate to a neighbourhood, not to a door, and the coordinates carry the same limit.
Do you keep or share the address?
Nothing is kept and nothing this page holds ever sends it anywhere; it is read from the request already being answered. The one external act is visible: the place line hands this address to ipinfo.io for that single lookup when the network answers.
What about IPv6 addresses?
An IPv6 address is reported exactly as it arrived and named as such; the place reading and the range table are written for IPv4 dotted quads.
