In this chapter, you have gained a solid understanding of the need for logical addressing on a network and have discovered both the IPv4 and IPv6 address spaces. You learned about the importance of NAT to help preserve the IPv4 public address space while allowing devices on a private network to communicate with hosts on a public network. Furthermore, you have gained the hands-on skills to convert IP addresses between binary and decimal. Additionally, this chapter covered the characteristics of various IPv4 and IPv6 address types and their role on a network.

I hope this chapter has been informative for you and is helpful in your journey toward learning networking and becoming a network professional. In the next chapter, Chapter 5, Applied IPv4 Subnetting, you will gain hands-on skills as a network professional to break down network blocks into subnetworks using the technique of subnetting.
