Look up an IP address
See approximate network location, ISP and ASN information. IP geolocation is an estimate and does not identify a street address.
How to use the IP lookup
- Enter one public IPv4 address, such as the address shown in your own connection scan, or a complete IPv6 address.
- Select “Look Up IP.” Do not paste a website URL, email address, port number or list of addresses.
- Read the approximate location alongside the network operator and ASN. Treat those fields as clues about the network, not a person.
Understand the three results
IP address: the address returned by the lookup service. Location: an estimate from its IP database. ISP and ASN: the network associated with the address; an ASN identifies an autonomous network. A network name can belong to a VPN host, transit provider or mobile operator rather than the company you pay for internet service.
Why the city may look wrong
Mobile networks, VPN exits and shared provider infrastructure can route traffic through another city. Databases update at different times. If two lookup services disagree, that alone does not prove either address is unsafe. Compare the expected country or network with your provider’s information before drawing a conclusion.
Private addresses and failed lookups
Addresses beginning with 192.168 or 10 are commonly local network addresses and do not have a meaningful public geolocation. An unavailable lookup can also mean a service limit, connection failure, browser restriction or unsupported address. Try once more later; do not interpret an error as a security verdict.
What is sent and when
Only after you select the lookup button, the entered address is sent directly from your browser to ipwho.is. That service also receives the connection information needed to handle your request. Do not submit an address if you do not want to share it with that service. The page does not save a lookup history.
The lookup cannot identify a household member, street address, account owner or criminal activity. Do not use approximate results to accuse, track or harass someone.
