CCNA Data Center - Introducing Cisco Data Center Networking Study Guide: Exam 640-911

Chapter 6

Easy Subnetting

The following topics are covered in this chapter:

• Describing an IP Addressing Scheme

• Describing Routing
• Understanding Numbering Systems
• Constructing a Network Addressing Scheme
• Subnetting

This chapter will pick up right where we left off in the last chapter. We will continue our discussion of IP addressing.

We’ll start with subnetting an IP network. You’re going to have to really apply yourself because it takes time and practice to nail subnetting. So be patient. Do whatever it takes to get this stuff dialed in. This chapter truly is important—possibly the most important chapter in this book for you to understand.

I’ll thoroughly cover IP subnetting from the very beginning. I know this might sound weird to you, but I think you’ll be much better off if you can try to forget everything you’ve learned about subnetting before reading this chapter—especially if you’ve been to a Microsoft class!

So get psyched—you’re about to go for quite a ride! This chapter will truly help you understand IP addressing and networking, so don’t get discouraged or give up. If you stick with it, I promise that one day you’ll look back on this and you’ll be really glad you decided to hang on. It’s one of those things that after you understand it, you’ll wonder why you once thought it was so hard. Ready? Let’s go!
