This page contains one exercise based on IP addressing and subnetting. At first the problem definition and some questions are given. Later, the solution of the questions are given. Please, at first try to solve yourself. When you have finished then look the answers / solutions. If you go forward in this way, I'm sure you do better.

[Note: Visit Subnetting Index or type http://hubpages.com/_ccna/hub/Subnet to your browser address bar to learn a-to-z of subnetting. Many examples are there to make you a smart master of subnetting.]
