What is the usable number of host IP addresses on a network that has a /26 mask?

  • 256
  • 254
  • 64
  • 62
  • 32
  • 16

Explanation: A /26 mask is the same as 255.255.255.192. The mask leaves 6 host bits. With 6 host bits, 64 IP addresses are possible. One address represents the subnet number and one address represents the broadcast address, which means that 62 addresses can then be used to assign to network devices.
