In this course, you will walk through the essentials of an IP address and then take a deep dive into subnetting IPv4 networks into smaller networks, as well as learn IPv6 addressing and how we can divide the very large IPv6 address space into smaller subnets.
As early as 1985, engineers knew there would be a shortage of IPv4 addresses before the end of the century. Over the next decade, engineers found a very clever solution to the problem, however it created a complex address. In this course, Network Layer Addressing and Subnetting, you will dive into extreme detail about the structure of an IPv4 address and its subnet mask counterpart. To do this, understanding binary numbers becomes very important. First, you will learn to describe how binary numbers work, how to convert from decimal to binary and back again, as well as see how hexadecimal easily integrates into binary. This may sound daunting, however, we keep the content simple and easy to follow, so it is not overwhelming. Next, you will explore how to understand binary and the structure of an IPv4 address, examining how to break a single IPv4 network into multiple IPv4 networks, understand the definition of a network address, broadcast address, and a host address. You will the examine how to calculate networks more efficiently using Variable Length Subnet Masking(VLSM), and to wrap up IPv4 addressing, we will take a simple IPv4 network, break it into 2 networks, and then observe its behavior across a router. Finally, you will wrap up IPv4, and move into IPv6, and understand the nuances of this new and obscure looking address. We keep it as simple as possible, so you understand the structure and operation of the IP address, without getting bogged down in nuanced details, infrequently used in IPv6. By the end of this course, you will have a much better grasp on IPv4 and a new understanding on the growing IPv6.
Course Overview Hi, everyone. My name is Ross Bagurdes, and welcome to my course, Network Layer Addressing and Subnetting. I'm a network engineer with more than 20 years professional experience managing enterprise networks and teaching people about them. The core of all things data networking, regardless if they're a traditional network or a software‑defined network, is IP addressing. In order to fully grasp IP addressing, one must understand subnetting. Now subnetting requires an understanding of some binary math and can be a challenge to learn in the beginning. However, this course will start with the basics and build up a solid skill set, so you'll leave with a deep understanding of IP addresses and subnetting. Some of the major topics that we'll cover include how to convert binary numbers to decimal numbers to hexadecimal numbers and back again. We'll learn the structure of an IPv4 and IPv6 address and identify the different types of addresses for each protocol. We'll learn how to use the subnet mask to identify IP address types, as well as break up big IP networks into smaller ones using subnetting. Before beginning this course, you should be eager and ready to understand the IP address operation and trying to suspend any anxieties you have about the math required to understand it. I hope you'll join me on this journey to learn IPv4 and IPv6 addressing with the Network Layer Addressing and Subnetting course, at Pluralsight.
