What is a private IP address, and what is the function of a private IP address?

A particular type of IP address is called a private IP address. In the current network, the IP address is divided into public IP and private IP address. Public IP is the IP address used on the Internet, while the private IP address is the IP address used in the LAN.

The number of IP addresses is now limited due to the limitations of the IP V4 protocol used before our SHUANGSE Qiu forecast. In this way, we cannot assign a public IP to each computer residing in the network. Therefore, each computer in the LAN can only use a private IP address, such as our common 192.168.0.*, is the private IP address.

A private IP address is a reserved IP address. It is only used on the LAN and is not used on the Internet.

The range of private IP addresses is:

Class A: 10.0.0.0-10.255.255.255

Class B: 172.16.0.0-172.31.255.255

Class C: 192.168.0.0-192.168.255.255

The above IP address can be used in the LAN.
