A $)$large number of consecutive IP address are available starting at $192\mathrm{.}16.0\mathrm{.}0.$Suppose that three organizations, A $,$B and C $,$request a $000($ a thousand $),$b $000($ b thousand $)$and c $000($ c thousand $)$addresses$,$ respectively, and in that order. For each of these, give the first IP address assigned, the last IP address assigned, and the mask in the w $.$ x $.$ y $.$ z $/$ s notation. The student should write details of calculations. $($ Note: a $,$b and c are defined as nonzero three numbers of student ID beginning from right. For example, if your student ID is $189203609$then a $=6,$b $=0$and c $=9.$So $,$organization A requests $6000,$B requests $0$and C requests $9000$addresses $).$
