Summary

Did you read Chapters 3 and 4 and understand everything on the first pass? If so, that is fantastic—congratulations! The thing is, you probably got lost a couple of times—and as I told you, that’s what usually happens, so don’t stress. Don’t feel bad if you have to read each chapter more than once, or even 10 times, before you’re truly good to go.

This chapter provided you with an important understanding of IP subnetting. After reading this chapter, you should be able to subnet IP addresses in your head.

This chapter is extremely essential to your Cisco certification process, so if you just skimmed it, please go back and read it and do all the written labs.
