An administrator wants to create four subnetworks from the network address 192.168.1.0/24. What is the network address and subnet mask of the second useable subnet?

  • subnetwork 192.168.1.64
    subnet mask 255.255.255.192
  • subnetwork 192.168.1.32
    subnet mask 255.255.255.240
  • subnetwork 192.168.1.64
    subnet mask 255.255.255.240
  • subnetwork 192.168.1.128
    subnet mask 255.255.255.192
  • subnetwork 192.168.1.8
    subnet mask 255.255.255.224

Explanation: The number of bits that are borrowed would be two, thus giving a total of 4 useable subnets:
192.168.1.0
192.168.1.64
192.168.1.128
192.168.1.192
Because 2 bits are borrowed, the new subnet mask would be /26 or 255.255.255.192
