You want to create a network of a private class A to accommodate a maximum of 1000 devices, equally distributed over four floors (each floor max 250 devices).

The computers on each floor must be kept on a separate subnet.

The network address space must be kept minimal (use optimal design).

Provide the following information:

A) The address of the super network (the aggregation of the four subnets).

B) The network address of the four subnets.

C) The subnet masks in both dotted decimal and slash notation, both for subnets and the supernet. 

D) The first and last available host addresses of the first subnet.

E) The broadcast addresses of the second subnet.
