SUBNETTING ASSIGNMENT – EXTRA CREDIT (30 points total)

Go to the following link and work through the Subnetting Tutorial until you reach Advanced Topics: www.subnetting.net/Tutorial.aspx. Advanced Topics will be covered in later classes. You will not need to understand Advanced Topics to complete these exercises. Each question is worth 3 points. IN ORDER TO GET CREDIT FOR A QUESTION, YOU MUST SHOW YOUR WORK OR EXPLAIN THE LOGIC OF HOW YOU ARRIVED AT YOUR ANSWER. NO EXCEPTIONS. This is imperative, and I will not give credit unless your work is shown. There are too many subnetting calculators on the Internet. I want to know that you understand the concepts taught in the tutorial, not that you can type numbers into an online calculator. I will give credit for any correct answers with work shown so it behooves you to turn in what you can, even if you cannot complete the entire assignment.
