How many host addresses are available on the network 172.16.128.0 with a subnet mask of 255.255.252.0?

  • 510
  • 512
  • 1022
  • 1024
  • 2046
  • 2048
    Explanation:

    A mask of 255.255.252.0 is equal to a prefix of /22. A /22 prefix provides 22 bits for the network portion and leaves 10 bits for the host portion. The 10 bits in the host portion will provide 1022 usable IP addresses (210 – 2 = 1022).
