IP geolocation and GPS location are frequently confused. An IP address may offer clues about the network a device is using, but it usually cannot tell you which house, room or exact street position a phone occupies.
Public IP-address databases often associate an address with a country, region, city, internet provider or network operator. The quality varies. Mobile carrier traffic may exit the network far away from the user's actual position, and VPNs or relays can make the apparent location even less representative.
Even when a city estimate is correct, that is a very different product from metre-level GPS.
Phones move between mobile networks and Wi-Fi, share carrier infrastructure with large numbers of users and regularly receive different IP addresses. Carrier-grade NAT can also mean many subscribers appear behind shared public addresses.
A website you visit can normally see the IP address from which your request arrives. That does not give the site a secret map of every future location of your phone.
GPS/GNSS positioning comes from radio signals received by the phone from navigation satellites. Android can also combine Wi-Fi, cellular and sensor information. Access to that location is controlled through the operating system's permission model.
For a deeper comparison, read GPS vs Wi-Fi vs cellular location.
It may be useful evidence in certain investigations, particularly when a service records account logins, but consumer recovery should begin with the device platform's own lost-phone tools rather than IP lookup websites.
Service providers and law enforcement may have information unavailable to the public, subject to legal process. That is fundamentally different from a public 'IP tracker' page.
LocationOf uses location data generated by its installed Android application. The internet connection transports location points to the service; the IP address is not used as a substitute for the phone's GPS position.
IP geolocation is still useful when used for the right question. A website can use it to choose a language, estimate a country for fraud checks, suggest a nearby region or flag an account login that suddenly appears to come from another part of the world.
Those are coarse contextual uses. If an IP database says 'Amsterdam', it does not follow that the phone is at a particular Amsterdam address; the user could be elsewhere in the Netherlands, behind a corporate gateway, on a mobile carrier exit node or using a VPN.
For account-security investigations, combine IP information with timestamps, device details and the provider's own security logs. For physically recovering a missing phone, use the device platform's recovery system instead of trying to turn a network address into a street-level GPS pin.
IP geolocation can still be useful when the question is coarse. Websites use it to estimate a visitor's country, choose regional content, detect an account login from an unexpected part of the world or identify the internet provider carrying a connection. Those are legitimate network-level uses.
If a database says “Amsterdam”, however, that does not prove the phone is at a particular Amsterdam street. Mobile traffic can leave a carrier network in another city, corporate gateways centralize traffic, and VPNs or privacy relays deliberately change the apparent network location.
An IP address can be one clue in an account-security investigation when it is combined with timestamps, device details and provider logs. It is not a substitute for a device-recovery system. To physically recover your own Android phone, start with Google Find Hub and any tracker that was already authorized on the device.
Be suspicious of paid services that convert a public IP lookup into a fake street-level map. A precise GPS position requires a credible source of location data, not merely an address used to route internet packets.
