Public IP address

A public IP address is a unique identifier assigned to a device connected to the internet, similar to a home address for mail delivery. It allows other devices and websites to find and communicate with your device online. Think of it as the device’s address on the internet that enables data to be sent and received between your device and the wider online world. Public IPs are assigned by Internet Service Providers and are necessary for accessing websites, sending emails, or hosting services. They are different from private IP addresses, which are used within local networks like your home Wi-Fi.
