    D．255.255.255.0

    E．255.255.255.224


    正确答案：C
    解析：Explanation:
    Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of networks.

    Again using the 2n-2 formula, we have 2n-2 = 126 networks that are available.

    Incorrect Answers:
    A. This will provide for only 1 network with 216-2 = 65534 hosts
    B. This will provide for 6 networks with 8190 host addresses.
    D. This will provide 254 networks and 254 hosts.
    E. This will provide 2046 different networks, but each network will have only 30 hosts.
