  4. Given the class B network address 128.10 will be divided into subnets. Compute (a) the minimum number of bits necessary to obtain the number of subnets required, (b) the subnet mask, (c) the maximum number of hosts in each subnet, and (d) write the dotted decimal address for each of the following scenarios:

    Subnet Mask     		(c)
    Max # Of Hosts/Subnet     		Subnet # Host # (d)
    Dotted Decimal IP Address
