A public IP address is a unique identifier assigned to a device connected to the internet. It is used to identify and locate the device on the internet and allows it to communicate with other devices. There are several ways to check your public IP address, including using online tools, command-line tools, or through your router’s settings.
Knowing your public IP address can be useful for a variety of reasons, such as troubleshooting network issues, accessing geo-restricted content, or setting up port forwarding. It can also be useful for security purposes, as it can help you identify unauthorized access to your network.
