What an IP lookup can tell you
This lookup combines public IP routing details with an approximate location estimate. The address and IP version identify the network address being checked. ISP or organization and ASN, when returned, describe the network that announces or operates it, not the person. A carrier, VPN, cloud host, university, or business can own the visible network even when the user is elsewhere.
Country, region, and city are labelled approximate because geolocation databases infer a likely area from network records, provider data, and routing clues. They can point to a provider's office, a regional gateway, or an outdated record. They cannot reliably give a street, home, or live GPS position. Timezone is also a database estimate for that area. Reverse DNS is a separate lookup: the network operator may have created a PTR record that maps the address to a hostname. Many valid addresses have no PTR record, and a hostname is not proof of who owns or uses the address.
How to read the result
For the default lookup, the page first asks this site's small same-origin endpoint which address connected to it, then passes that address through one shared geolocation provider chain. When you enter a different public address, the same provider chain receives that address and returns whatever fields it has. One provider may not have organization, ASN, city, or timezone data; blank fields mean unavailable, not that the address has no network owner. The reverse-DNS query is made separately and can also return no hostname.
Private and special-use addresses are refused. This includes RFC 1918 home or office ranges, carrier-grade NAT space shared by internet providers, loopback addresses that refer back to the same device, link-local addresses used on a local network, and IPv6 unique-local addresses. These ranges are not globally routable, so public geolocation and reputation data would be misleading. A public address can still belong to a VPN or hosting provider. If you need a router's local address, read our guide to finding a local IP.
What to do with an unexpected location
Compare the displayed address with the one in your VPN application or router status page. Disconnecting a VPN may change both the address and its approximate location. If the address is yours but the city looks wrong, the result usually reflects how the provider registered or routes the block, not a problem with your device. Your provider may be able to confirm which public address was assigned at a particular time. The IP location guide explains common causes. Never use an IP lookup as identity verification or as evidence of someone's precise location.
Frequently asked questions
Can an IP address show someone's exact address?
No. IP geolocation is an estimate, commonly at country, region, or city scale. Only the network provider can associate a dynamic assignment with a subscriber and time, subject to its records and applicable law.
Why can the ISP or city be missing?
Provider databases differ. A geolocation provider may not have current details for a small, new, mobile, or reassigned network block.
What does reverse DNS mean?
It is an optional PTR record that maps an IP address to a hostname. Many addresses have no PTR record; when present, the name is maintained by the network owner.
Does this request get saved?
The result is not saved in browser storage. The site's server and the geolocation or DNS providers process the address to answer the request; see the privacy page for the exact data path and standard hosting logs.
