Who's behind an IP address?
Enter any IP address to see which network it belongs to, where it's registered and what kind of connection it is. Handy for addresses in email headers, router logs or games.

Addresses you look up aren't stored. ip5.io asks Cloudflare DNS who owns them.
Not the person. A lookup shows the network that owns the address, usually an internet provider, a mobile operator or a hosting company. Only that provider knows which customer used it at a given time, and it shares that only with the police or a court.
The country is where the address block is registered, which is usually where the provider is based. Big networks like Google or Cloudflare register addresses in one country and use them worldwide, and VPNs make an address appear far from its user.
It's a private address. Home and office routers give these to the devices inside, and millions of networks use the same ones, so they don't lead to anyone on the internet. Your public address is the one on ip5.io's main page.
Networks get addresses in ranges, written like 8.8.8.0/24. The number after the slash says how big the range is: /24 is 256 addresses, /19 is 8,192. Every address in the block belongs to the same network.
Yes. Who owns which addresses is public information that internet registries publish for everyone. A lookup shows the network, not the person, and the address's owner isn't told that you looked.
