While Chapter 5 briefly discussed IP addresses and their types, this chapter focuses on IP addressing, its components, and how to plan addressing. Note that there are two different versions of TCP/IP addressing: IPv4 and IPv6. 32-bit IPv4 addressing is covered in this chapter, and 128-bit IPv6 addressing is covered in Chapter 23. Before reading this chapter, you should go back and review the binary and hexadecimal conversion process introduced in Chapter 3, as this chapter makes extensive use of these concepts.Certification II Label 6.016.1 Reviewing IP AddressingAs stated in Chapter 5, an IPv4 address is 32 bits long and is divided into four bytes, with adjacent bytes separated by periods, often referred to as the dotted decimal format. This address consists of two parts: the network number and the host number, the combination of which must be unique throughout the network. IP addresses are similar to the ZIP codes used by the U.S. postal system; when you write a letter and drop it in your mailbox, the postal workers don't care who the recipient is or what the recipient's street address is; they look at the ZIP code and drop the letter into the appropriate container behind them accordingly Inside. For example, if the ZIP code begins with a 3, the letter is placed in the container intended for the southeastern United States. At a regional post office, the worker puts the letter into the container that indicates the state (if the ZIP code begins with 32, it is destined for Florida), and the process repeats until the letter reaches the post office closest to the recipient (if the ZIP code is 32765, the letter will arrive in Oviedo, Florida).
