ake your nine$-$digit student ID $100$xxyyzz$,$ and create an IP address in form of $100.$xx$.$yy$.$zz from it$.$ For example if your student ID is $100963897,$ your assigned IP address will be $100\mathrm{.}96\mathrm{.}38\mathrm{.}97.$ Using your IP address and assuming the subnet mask $255\mathrm{.}255\mathrm{.}252\mathrm{.}0,$ answer the following questions: a$.$ Calculate the network address in which your assigned IP address resides, the broadcast address, the first valid host address, the last valid host address and the total number of valid host addresses in this network. $(20$ marks$)$ b$.$ Divide the network address range from part $(1)$ into eight equal$-$size subnets, and calculate the network address, subnet mask and broadcast address for each of those subnets. How many usable host addresses exist in each of those subnets? $(20$ marks$)$ c$.$ What is the maximum number of subnets I can fit into the network from part $(1)$ if each subnet is to accommodate up to $50$ hosts? $(10$ marks
