A technician has been asked to assign an IP address to a new desktop computer.

172.16.2.189 is a valid IP address that a technician can assign to a new desktop computer. An IP address is a unique identifier that is assigned to a device on a network that uses the Internet Protocol (IP). An IP address consists of four numbers separated by dots, each ranging from 0 to 255. For example, 192.168.1.1 is an IP address. An IP address can be classified into different classes based on the first number: Class A (1-126), Class B (128-191), Class C (192-223), Class D (224-239), and Class E (240-255). Each class has a different range of IP addresses that can be used for public or private networks. 172.16.2.189 is a Class B IP address that belongs to the private network range of 172.16.0.0 to 172.31.255.255. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 165.
