Suppose that the Green University of Bangladesh is granted block $107\mathrm{.}108\mathrm{.}22\mathrm{.}128/16.$ The administrator

wants to create eight subnets from the block for eight departments. The CSE dept will need $252$

addresses, the EEE dept will need $60$ addresses, Textile, GBS$,$ and English dept each will need $60$

addresses. And the remaining $3$ departments i$.$e$.,$ Law, sociology, and JMC departments will need $15$

addresses.

Design the subblocks by giving the network address and address range using lash notation i$.$e$.,$ in the form of

a$.$b$.$c$.$d$/$x for each subblock. Finally, analyze how many addresses are still available after these allocations.
