About this tool
Enter a public IP address to see who it belongs to, the network range it sits in, its network number and its reverse DNS name. Ownership comes from the regional internet registries, so it needs no key. The country is where the network block is registered, and it is only approximate. Private addresses like 192.168.0.1 are refused with an explanation.
Common questions
Is the location exact?
No. It shows the country where the address block is registered, which often matches where the provider is, but not where a person is. City-level location needs a paid database.
Why is my own address a private one?
Addresses like 192.168.x.x are used inside home and office networks. The public address your network shows to the internet is the one that can be looked up.
Where does the data come from?
From RDAP, the free lookup service run by the registries, plus public DNS for reverse names and network numbers.
Is it free to use?
Yes. There's no sign-up, and you can use it as often as you like.
Do I need to install anything?
No. It works in your browser on a computer or a phone.
Is what I enter kept?
It's only used to get your result. Some public answers, such as the branches for a pincode, are kept for a while so the next lookup is quicker, but nothing links them to you.
