Suppose you have the following network requirements, for Given an IP address and mask of $9\mathrm{.}0\mathrm{.}0\mathrm{.}08,$ design an IP addressing scheme using VLSM$?$ How is the efficlency of this method achieved? Use the topology in Figure to answer the questions.

a$.$Network $1$ needs to support $30$ host addresses.

b$.$Network $2$ needs to support $662$ host addresses.

c$.$Network $3$ needs to support $2$ host addresses.

d$.$ Network $4$ needs to support $52$ host addresses.

e$.$Network $5$ needs to support $255$ host addresses.

f$.$ Network $6$ needs to support $62$ host addresses.

g$.$Network $7$ needs to support $2$ host addresses.

h$.$ Network $8$ needs to support $2$ host addresses.
