Question

What is the range for a Class B network block?

1) 10.0.0.0 - 10.255.255.255
2) 172.16.0.0 - 172.31.255.255
3) 192.168.0.0 - 192.168.255.255

Answer 1

The range for a Class B network block is 128.0.0.0 to 191.255.255.255, but for a private Class B network, the correct range is 172.16.0.0 - 172.31.255.255, which is Option 2.

Step-by-step explanation:

The correct range for a Class B network is not listed among the options provided. Class B networks have IP addresses that range from 128.0.0.0 to 191.255.255.255. However, the options given seem to refer to private IP address ranges. For clarity:

• Option 1: 10.0.0.0 - 10.255.255.255 is the range for a Class A private network.
• Option 2: 172.16.0.0 - 172.31.255.255 is the range for a Class B private network.
• Option 3: 192.168.0.0 - 192.168.255.255 is the range for a Class C private network.

Therefore, if the question is about private IP address ranges, the correct answer for a Class B private network is Option 2.
