You need to set up 200 computers on a Class A private network. Which of the following network IDs meet all the criteria of a Class A private network? 0000 192.168.1.0 100.10.1.0 172168.0.1 10.0.00

The correct answer is $10.0.0.0$.<br /><br />Explanation:<br />A Class A private network has a default subnet mask of 255.0.0.0, which means the first octet is used for the network portion and the remaining three octets are used for the host portion. The range of IP addresses for a Class A private network is from 10.0.0.0 to 255.255.255.255.<br /><br />Among the given options, only $10.0.0.0$ falls within the range of a Class A private network. The other options are not valid network IDs for a Class A private network.
