What Is My Public IP Address?
The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet.
Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet.
An IP address is written in "dotted decimal" notation, which is 4 sets of numbers separated by period each set representing 8-bit number ranging from (0-255). An example of IPv4 address is 18.104.22.168, which is your IP address.
Every device on the Internet has two IP addresses: a public and a private one. In your home, your router uses your public IP address—assigned by your ISP—to connect to the Internet.
Your mobile devices also have public and private IP addresses. But they're constantly changing, and therefore, pretty much meaningless.
Your public IP address is the IP address that is logged by various servers/devices when you connect to them through your internet connection.
Geo tracking has become very common today. A network of satellites and mobile phone towers help in providing the exact location of an IP address. If you want to know where an IP address is located, you must use this geo IP locator tool.
