What websites see
Every website you visit sees this IP address and can estimate your city, provider and connection type from it.
IPv4 or IPv6?
If you see an address with colons, you are connected over IPv6. Most networks now support both.
Building this into an app? Use the IP geolocation API and its IP info endpoint documentation.
Public vs private IP address
| Property | Public IP | Private IP |
|---|---|---|
| Visible to | Every website and service you use | Only devices in your network |
| Assigned by | Your internet provider | Your router (DHCP) |
| Examples | 81.2.69.160, 2a02:… | 192.168.0.10, 10.0.0.5 |
IPv4 vs IPv6
IPv4 addresses (like 203.0.113.7) are running out, so providers increasingly give out IPv6 addresses (like 2001:db8::7). If your address above contains colons, your connection uses IPv6. Many devices have both and use IPv6 when the website supports it.
