Summary

In this chapter, we started by covering a brief history of IP. We learned how both versions of IP can do the job of routing and addressing; however, there are several differences between the IPv4 and IPv6 headers. We examined and explained each of the field values of both IPv4 and IPv6. Additionally, to give you a better understanding of the two protocols, we compared some of the similarities along with the differences between IPv4 and IPv6.

To help strengthen your knowledge of addressing, we briefly covered the classes of IPv4 addresses, along with reviewing the different types of IPv6 addresses. We then looked at how you can personalize the settings for IPv4 and IPv6 by modifying the protocol preferences. Finally, because of the need for both IP versions to coexist on today's networks, we compared the different types of tunneling protocols in use today.

In the next chapter, we will learn about ICMP, the companion protocol to IP, which works in the network layer...
