How many valid host addresses are available on an IPv4 subnet that is configured with a /26 mask?

  • 254
  • 190
  • 192
  • 62
  • 64
    Explanation:

    When a /26 mask is used, 6 bits are used as host bits. With 6 bits, 64 addresses are possible, but one address is for the subnet number and one address is for a broadcast. This leaves 62 addresses that can be assigned to network devices.
