Basic Knowledge
Difference Between Global IP and Private IP
A global IP is a unique address worldwide that identifies you on the internet, while a private IP is an address used only within your home or corporate network (such as 192.168.~). External sites can see your global IP.
Why Does Your IP Address Change?
On typical internet connections, your provider dynamically assigns IP addresses, so your IP may change when you restart or reconnect your router. For purposes requiring a static IP, a fixed IP plan is used.
Why is the geolocation different from the actual location?
The geolocation of an IP address is not measured from the device's actual location, but is an estimate inferred from the region where the Internet Service Provider has assigned that IP address. For this reason, with home Wi-Fi or mobile phone connections, a different city or municipality within the same prefecture may be displayed, and this is not a display error but a result of how the estimation works.
Safety and Privacy
Server-side processing
Input is processed on the server; only information necessary for the inquiry is sent.
Temporary processing only
For Location acquisition, temporary processing occurs on the server, then data is discarded after results are returned.
Communications encrypted with HTTPS
All sent and received data is encrypted by TLS and cannot be read by third parties.
No transmission to third parties
Input content is not sent to external services such as ad networks or trackers.
Transmission to location API only
For location information retrieval, only the target IP is sent to external APIs.
