What Is an IP Address & Why Does It Matter?
An IP address (Internet Protocol address) is a unique number assigned to your device whenever it connects to the internet. It tells websites and servers where to send the data you request — like a return address on a letter. Your IP address can reveal your approximate location, internet provider (ISP), and whether you're on a home or mobile connection. Use this tool to instantly see what information your IP exposes to every site you visit.
