A company with an IP network address of 173.95.0.0 has just retained your services in
the area of network design. They have seven divisions running token ring, and each
division is located in a different geographical area. The seven areas are mesh-connected
by 56 kbps WAN links. Two of the divisions have twenty to thirty hosts each, and the
remaining divisions have between forty and fifty hosts each. If each division requires its
own subnet, what subnet mask(s) will satisfy the requirements? Based on your choice of
subnet mask, what is the maximum number of hosts that a division can have, and how
many divisions are possible on the network?
