Problem 2.4. IPv4 addressing basics and a problem subnetting solves. Suppose that the need per enterprise is K IPv4 addresses; for simplicity, assume that K is a constant. Calculate N(K), the number of enterprises we can accommodate with class A addresses and no subnetting; calculate W(K), the waste of addresses (define the term carefully). Plot both as a function of K. State your assumptions clearly. In your plots, use K values that are feasible for IPv4 (but not necessarily meaningful for the size/needs of an enterprise.
