What is Public IP Address
Your public IP address is the IP that is logged when you visit websites or use any other services on the Internet. It differs from your private IP address, which varies by individual device as each device is assigned a private IP address.
A public IP address is a unique address assigned to a device by an Internet Service Provider (ISP). It serves as an identifier for your device on the internet and allows other devices to connect and communicate with it.
Public IP addresses are required for devices that need to be directly accessible from the outside world, such as servers or devices hosting services like websites, mail servers, etc.
