About This Chapter
IP Addressing - Chapter Summary
Check out this comprehensive computer science chapter to learn or review the fundamentals of IP addressing. After reviewing the components of IP addresses, you'll take a look at a variety of concepts, including hostname resolution, IPv4 addresses, network segmentation, IP subnetting and much more. If you want to see how well you comprehend these IP address concepts, take the short quizzes that accompany each lesson. The chapter can be accessed online at any time that fits your schedule, and we encourage you to submit questions to our computer science experts if you need clarification on any lesson topic. When you're finished with the chapter, you should be able to:
- Define the term IP address
- Explain the concept of hostname resolution
- Discuss the functions of IP addresses, URLs, ISPs, DNS and ARPANET
- Compare types, classes and structures of IPv4 addresses
- Describe the role of ICANN and IANA in IP address management
- Outline network segmentation and IP subnetting processes
1. What is an IP Address? - Definition & Explanation
In this lesson, we will learn the basics of IP addresses, how and why they are used, and their role in the world of the internet. We will understand binary and decimal notations and the role of subnets in identifying networks.
2. What is Hostname Resolution?
Hostname resolution makes it easy to locate a system on a large network. In this lesson, we will see what Hostname Resolution is all about and how a System Administrator would make use of it.
3. The Internet: IP Addresses, URLs, ISPs, DNS & ARPANET
We'll cover the basics of the Internet, including its history and functioning. Key topics include IP addresses, TCP/IP communication protocol, DNS, URLs, and the transfer of information as packets through the Internet.
4. IPv4 Address: Structure, Classes and Types
In this lesson, you will learn the concepts of IPv4 Address and its structure. The IP address classes, as well as the fields associated with an IP packet, are also discussed in this lesson.
5. The Role of IANA & ICANN in Managing IP Addresses
We'll talk about the roles of IANA (Internet Assigned Numbers Authority) and ICANN (Internet Corporation for Assigned Names and Numbers) in managing domain names and IP addresses and also learn how they help in keeping the Internet stable and secure.
6. Network Segmentation & IP Subnetting: Definition & Processes
In this lesson, we will learn about what is Network Segmentation and why we need to segment a network. We will also discuss about how to achieve Network Segmentation using IP Subnetting.
