Both private and public IP addresses accomplish the same thing: they allow devices to communicate with each other. The difference between these two types of addresses is the types of devices that they allow to communicate. The most important factors of private and public IP addresses are as follows: Private IP addresses: Devices that are assigned private IP addresses are not accessible by the devices on the public internet. In other words, devices with private IP addresses can only communicate directly with other devices that have private IP addresses. Private IP addresses are used in home and office networks, and their purpose is to limit the number of public IPv4 addresses used by a home or business. There are a limited number of public IPv4 addresses that are available, and this is the reason why private IPv4 addresses were developed in the first place. Public IP addresses: Public IP addresses are used for devices that are accessible on the public internet. A device that’s assigned a public IP address can be accessed by any device that has a connection to the internet. The best example for where public IP addresses are used is when they are assigned to websites. Websites are public resources that are accessible by anyone with a connection to the internet, and the public IP address they’re assigned is how you access your favorite websites. Even though there are a limited number of public IPv4 addresses, another type of IP address (called IPv6) has been developed to ensure we don’t run out of public IP addresses as the internet continues to grow at unprecedented rates.
