What distinguishes a public IP address from a private IP address?

Public IP addresses are routable over the internet, which means they can be accessed from any device connected to the global internet. This connectivity is essential for hosting services, websites, or any resources that need to be reachable by the public. In contrast, private IP addresses are designed for use within a local network and cannot be routed on the internet. They are typically used in home networks or internal enterprise networks where devices need to communicate with each other without exposing their addresses to the outside world.

Furthermore, the unique characteristics of public IPs facilitate broader connectivity, as they can be assigned to a device that requires access to the internet, ensuring that it can send and receive data effectively. This is a fundamental aspect of how the internet operates, allowing different devices and networks to connect with each other around the globe.
