Problem
As the network administrator for a growing ISP, you want to make efficient use of your network addresses. One of the network addresses IANA assigned to you is a Class C network of 197.14.88.0. You have decided to use the addresses in this Class C network to satisfy the IP address requirements of 16 corporate customers who need between 10 and 14 addresses each. Calculate a subnet mask that meets their needs. List the subnet mask and the first four subnet addresses the mask will create.
