Your public IP, location, ISP & connection details — detected in real time.
Your public IP is the unique address your ISP assigns to your internet connection. Every website you visit can see it — it's how data finds its way back to you.
They can see your approximate city and country through your IP, but not your home address. Your ISP's nearest server location is what gets detected.
IPv4 looks like 103.189.61.2. IPv6 is longer and newer, created because the world ran out of IPv4 addresses. Most connections today support both.
Most home ISPs assign dynamic IPs that can change when you restart your router. Businesses usually have static IPs. Using a VPN also changes your visible IP.
Using a VPN routes your traffic through a different server, masking your real IP. Tor browser also hides your IP but is slower.
