Learn a four-step method to "see" an entire subnetwork's worth of IP addresses in your head. Bill Ferguson reveals the secrets to determining IP ranges and broadcast addresses without the use of subnet calculators or any binary translation.
- [Bill] Welcome to Subnetting In Your Head. A few years ago, I became convinced that there was a better way for students to learn to subnet IP addresses. I wanted to develop a method that did not require converting numbers to binary or memorizing a chart to obtain the answers. I'm Bill Ferguson, and I'm excited about sharing this subnetting method with you. I've been an IT instructor for over 20 years. I used the tips and wisdom of those who taught me to develop my own four-step method of IP subnetting, that, with a little practice, will enable you to subnet Class A, B, and C addresses in your head.
This course brings his method to life more than ever before. We will start off by examining the original classful system developed by the Internet Corporation of Assigned Names and Numbers, ICANN, and the Internet Engineering Task Force, IETF. The original system is what I call the DNA of IP addressing. Then, we will discover how the same rules that they established for the classful system of IP addressing can be used for any custom subnet as well.
You will learn to use my four-step method to see the IP addresses of the custom subnets. Finally, you will learn how this new knowledge and skill can benefit you in real world situations and on IT certification tests. So we've got a lot to cover. Let's get started.
Discover how IP addresses are constructed and how to understand them better by relating them to a picture rather than converting binary numbers or memorizing charts. Learn the benefits that subnetting in your head provides in every aspect of IT networking, including routing protocols, access control lists, and network address translation. Then walk through Bill's four-step method, which leverages the rules that were used to create the original classful IP addressing schemes. Using this method, students can learn to "see" the IP addresses for each subnet. Watch the technique in action, and then practice what you've learned using the audio guides in chapter five, which provide auditory cues as you subnet in your head.
