How to use this tool
Enter an IP address to see its canonical form, version and public/private-or-reserved classification.
Important to know
Check the format and scope of an IPv4 or IPv6 address.
This is not a geolocation, ownership, ISP or threat-intelligence lookup. Address classification is not a claim about physical location.
Formula and methodology
Validate the address using IP parsing, normalize its representation and classify private/reserved ranges.
Example
192.168.1.1 is an IPv4 private address.
Frequently asked questions
Can this tell me where a person lives?
No. An IP address alone does not establish a person’s precise location.
