IP Addressing and Subnetting Trong Chương 5, "nguyên tắc cơ bản của IP, bạn đã học về các khái niệm cơ bản và thuật ngữ liên quan đến địa chỉ IP. Những khái niệm này đã được giới thiệu trong cuốn sách bởi vì sự hiểu biết của bạn về khái niệm mạng cơ bản phụ thuộc vào kiến thức cơ sở của địa chỉ IP. Trong chương này, bạn sẽ tìm hiểu về các khái niệm và toán học cho phép bạn phân tích địa chỉ IP và các mạng con. Địa chỉ IP là chủ đề lớn. | C H A P T E R IP Addressing and Subnetting In Chapter 5 Fundamentals of IP you learned about the basic concepts and terminology relating to IP addressing. These concepts were introduced early in the book because your understanding of many basic networking concepts depends on a base knowledge of IP addressing. In this chapter you will learn about the concepts and mathematics that let you analyze IP addresses and subnets. IP addressing is the only major topic that happens to get coverage on both of the INTRO and ICND exams. To answer questions on either CCNA exam you will need to discover the structure of IP addresses list the addresses in the same subnet list the other subnets of that same network identify the numbers of hosts in a subnet and identify other information about addresses and subnets. This chapter describes the math and processes used to answer these questions. This chapter also happens to cover a few topics related IP address scalability issues related to Internet growth. Do I Know This Already Quiz The purpose of the Do I Know This Already quiz is to help you decide whether you really need to read the entire chapter. If you already intend to read the entire chapter you do not necessarily need to answer these questions now. The 14-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. Table 12-1 outlines the major topics discussed in this chapter and the Do I Know This Already quiz questions that correspond to those topics.
