A network administrator is given the network prefix 10.25.0.0/16. What subnet prefix would provide the organization with 512 subnets, each capable of supporting at least 100 hosts?

Explanation: The calculation should start with the IPv4 prefix 10.25.0.0/16, a subnet mask of 255.255.255.128 is required to create 512 subnets, each can accommodate at least 100 hosts. The subnet mask 255.255.255.128 is equivalent to the notation of /25. The difference between /16 and /25 is 9 bits. 9 bits will produce 512 subnets. A subnet mask notation /25 allows 7 bits for hosts. 7 bits provides for 126 hosts.
