CHAPTER 9
Internet Protocol Version 6
This chapter reviews Internet Protocol Version 6 (IPv6) address structures, address assign-
ments, representations, and mechanisms used to deploy IPv6. Expect plenty of questions
about IPv6 on the exam. The CCDA must understand how an IPv6 address is represented
and the different types of IPv6 addresses. This chapter also covers the benefits of IPv6
over IPv4, compares the protocols, and examines migration to IPv6 options.
As IPv6 matures, different deployment models will be used to implement the new proto-
col with existing IPv4 networks. This chapter covers these models at a high level. This
chapter does not discuss the configuration of IPv6 because it is not a requirement for
CCDA certification.
The “Do I Know This Already?” quiz helps you identify your strengths and deficiencies in
this chapter's topics.
The 13-question quiz, derived from the major sections in the “Foundation Topics” portion
of the chapter, helps you determine how to spend your limited study time.
Ta ble 9 -1 outlines the major topics discussed in this chapter and the “Do I Know This
Already?” quiz questions that correspond to those topics.
