What is a public IP address?

Direct answer: A public IP address is the address your internet provider (or mobile carrier) exposes to the rest of the internet so servers can send data back to you. Tools like What Is My IP Address IP show that address in your browser.

How it differs from a “local” IP

Devices on your home network often use private ranges (for example 192.168.0.x). Those are not globally unique. Your public IP is what the wider web associates with your connection at that moment.

Does it change?

It can. Many residential connections use dynamic public IPs that rotate. Business lines or special plans may have static IPs. VPNs replace the visible public IP with the VPN exit node’s address.

Open What Is My IP Address IP to read your current IPv4 and IPv6 when available.
