IP Address Inspector is a tool for dissecting IP ranges, the calculation runs in your browser, so your figures never reach a server.

Results update as you change any field; copy them into a sheet or quote.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

Which ranges are private?+

10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16, plus 127.0.0.0/8 loopback and 169.254.0.0/16 link-local.

Can it find my IP location?+

No. Geolocation needs a third-party database and network access. This tool analyses the address structure only and makes no requests.

Is IP Address Inspector free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does IP Address Inspector work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
