Which of the following IP address groups can be used for assignment to computers using the public Internet?

A. 10.0.0.0–10.255.255.255

B. 12.222.0.0–12.222.255.255

C. 172.16.0.0–172.31.255.255

D. 192.168.0.0–192.168.255.255

Solution

Answer B is the correct answer. It is the only IP address shown in the four options that is a routable IP address. The address groups listed in answers A, C, and D are reserved for private networks and are not routed by the Internet, so those answers are incorrect. You will need to memorize the address groups reserved for private IP networks.
