ADRAMADA: Practical Subnetting For Certifications And Pros

Dave Rush presents a Practical Subnetting guide for everyone from beginning students to seasoned network professionals though foundational concepts through subnetting Class A, B and C IP network addresses. Each section comes with downloadable, follow-along slides that can be used to review well after you complete the course. Each section will also have an end-of-section quiz and there is a practice exam at the end of the course to test all of the covered topics. (Note - we're furiously writing the quizzes and practice test as quickly as possible. They should be added by mid-April, 2025).The course opens with a basic overview of IP address notations. From there, we present binary and base-2 number systems, using base-10 concepts to review how binary notation works. We illustrate how there is only one combination of 1s and 0s to represent any number. Students will easily be able to convert back and forth between binary and decimal numbers.Next, we introduce the concept of Classful IP addressing. This was how the first Internet addresses were distributed to users, organizations and Internet Service Providers (ISPs). Classful addressing is a fundamental and critical concept to understanding subnetting. With Classful addressing comes the concept of a subnet mask, network address classes and the skill to quickly identify a class of address, its subnet mask and which octets are used in the network address and which are used in host/node addresses.We continue our exploration of Classful addressing to review special IP addresses. We present the uses of special IP addresses and what makes them so special.With these concepts secure, we're ready to delve into the seemingly mysterious and arcane world of subnetting. Using the step-by-step approach, we learn the reasons for subnetting and a simple, four-step process. By provide extensive demonstrations and explanations, student gain confidence and competence in moving from a Classful IP addressing
