Which country is this IP address from?
A strange login, a burst of visits, an address in a firewall report: the first question is always “where is this from?”. This answers it for one address or ten thousand, and nothing leaves your device.

How it works
- Paste the addresses or the text that contains them, or drop a log file — the tool picks out every IPv4 and IPv6 address it finds.
- Press “Look up the countries”. The first time, the browser downloads a country table of about 770 KB; after that it works offline.
- Read the count by country and the list, and download the CSV if you need it in a spreadsheet.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
How can it know the country without asking a server?
Every public address belongs to a block that a company or provider registered somewhere in the world. Those blocks and their countries are public data. The tool downloads that table once (DB-IP Lite, updated monthly) and looks your addresses up in it, inside the browser — the same way a paper phone book works.
How accurate is it?
Country level is usually right; city level is not attempted. An address shows where its block is registered or mostly used, so a VPN, a mobile carrier or a big cloud provider can point to a different country than the person using it. Treat it as a strong hint, not proof.
What does “unassigned / private” mean?
Addresses like 192.168.x.x or 10.x.x.x are private — they exist only inside a home or office network — and some ranges are reserved or not yet given to anyone. None of those has a country.
Can I use it on a whole log file?
Yes. Drop the file, or paste the text; the tool finds the addresses inside it and counts them. Files stay on your device — the site never receives them.
