About the IP Address Classification

IP Address Classification is a focused network utility for administrators, developers, support teams and people troubleshooting an internet connection. Identify public, private, loopback, link-local and other special-use IP ranges.

The calculation runs locally in your browser, so the address is not uploaded.

Results describe public network information and should not be treated as proof of a person's identity or exact physical location.
