Join Bill Ferguson for an in-depth discussion in this video What you should know, part of Subnetting in Your Head.
- [Instructor] Sometimes people wonder whether this is the right course for them and whether they have the prerequisite knowledge for the course. So, I want to let you know that you don't have to be a networking expert. You only have to understand general network concepts. We're going to talk about subnetting, so you should understand why we would have subnets in networks. But you don't have to understand everything about networking.
Also, you should be able to solve simple mathematical problems. You don't have to be a math whiz. We're going to use simple methods to solve our IP subnetting problems. And the whole idea is to learn to do it in your head. So, we're going to use the knowledge that you already have. So the main thing that you should know is that you want to learn to subnet IP addresses in your head.
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.
