Private IP addresses

Unlike a public IP address, a private IP address is considered to be any IP address that enables a device to be accessed from anywhere on the intranet. Naturally, a private IP address uniquely identifies a device on the intranet. That is also why a private IP address is often called a Local IP address. In addition, a private IP address is a non-routable. The IANA has specified the following IP address ranges for private use:

Class

Address Range

A

10.0.0.0 - 10.255.255.255

B

172.16.0.0 - 172.31.255.255

C

192.168.0.0 - 192.168.255.255
