Read guideWhat is my public IP address?
Your public IP is the address websites see when your connection reaches them. It may belong to your home router, a mobile gateway, a VPN, or a company network. Devices inside your home usually have separate private addresses.
IPv4 and IPv6 are two ways to address devices on the Internet. You may have both, only one, or different routes for each. The checks above ask your browser to reach separate endpoints so you can see what this connection exposes.
