IP Address Lookup

Check the approximate country, region, city, ASN and network organization associated with a public IP address.

This live lookup sends only the IP address or hostname you enter to the named public lookup service. Do not submit private hostnames or confidential infrastructure details.

About the IP Address Lookup

IP Address Lookup is a focused network utility for administrators, developers, support teams and people troubleshooting an internet connection. Look up the approximate location, ISP and network details of a public IPv4 or IPv6 address.

Live results use a public lookup service. Only the address or hostname submitted for lookup is sent to that service.

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