Appendix J. Practice for Chapter 28: Fundamentals of IP Version 6

This appendix provides extra practice problems for two topics discussed in Chapter 28, “Fundamentals of IP Version 6,” of the book. The first problems let you convert from a full 32-digit IPv6 address to its abbreviated form, or to do the reverse. The second set of problems begins with IPv6 addresses and prefix lengths, asking you to determine the IPv6 prefix (subnet).

Table J-1 lists some practice problems, with the full 32-digit IPv6 address on the left and the best abbreviation on the right. The table gives you either the expanded or abbreviated address, and you need to supply the opposite value. The answers sit at the end of the appendix, in the section “Answers to Address Abbreviating and Expanding Problems.”

Table J-2 lists practice problems that all use the same prefix length (/64), which is the most common prefix length you see. Table J-3 that follows lists additional practice problems, with prefix lengths other than /64.
