    Default 150.48.0.0/4 network block?

    i have little tricky question.

    Assume that you have been assigned 150.48.0.0/4 network block. You need to establish sixteen(16) subnets

    a. specify the extended network prefix that allows the creation of sixteen subnets

    b. express the subnets in binary format and dotted-decimal notation for the first 4 subnets(of the 16 subnets)


    how can i solve this question.
    could someone help me_?

    The largest block you could assign to 150.x.x.x is /16 its a class b network. (Unless CIDR is in use)
    So lets assume your block is 150.48.0.0/16.

    To get 16 useable subnets your new mask would be 255.255.240.0 150.48.0.0/20

    For part b your subnets would be
    150.48.0.0
    150.48.16.0
    150.48.32.0
    150.48.48.0
