What Is a Public IP Address?

A public IP is the address the rest of the internet sees for your connection. Your devices at home share it through your router, which uses private IPs inside.

The short answer

Your public IP is the address websites see. At home, your router has one public IP, and every device behind it (laptop, phone, TV) uses a private IP such as 192.168.1.20 that only exists inside your network.

Why it matters for proxies

A proxy swaps your public IP for its own. To check that a proxy works, compare the public IP a "what is my IP" page shows with and without the proxy. If they match, the proxy is not being used.
