Learning Subnetting

  • Course details

    IP subnetting is one of the most challenging, yet most critical, skills for IT professionals to acquire. In this course, you can learn the basics of IPv4 addressing and master the skill of IP subnetting. Explore the structure of an IPv4 address and the difference between public and private IPv4 addresses. Learn how to convert between binary and decimal numbers. In these chapters, instructor Kevin Wallace explains how to determine the subnet bits you need in order to create a specific number of subnets, how many host bits are required to support a specific number of hosts, and the range of usable addresses for each subnet. Plus, learn how to troubleshoot incorrectly assigned IPv4 addresses and use Classless Interdomain Routing to efficiently summarize IP addresses.

  • Simplify IP subnetting

    - Hello, and welcome to Learning Subnetting. My name is Kevin Wallace and I'm going to be leading you through a series of videos designed to help you get great at the skill of IP subnetting. Maybe you're doing this for the real world, or doing some sort of a design. Maybe you're going after certification. This skill is critical for certifications such as Cisco's CCNA in Routing and Switching, and CompTIA's Network+ Certification. But regardless of your motivation, here's what we're going to be learning. We're going to start out by understanding why do we need IP subnetting in the first place and what is it? Then, we'll get a bit mathematical. We'll start out easy with some binary numbering, and then we'll build on that. We'll be able to calculate the number of hosts in a subnet. We'll be able to say given a specific subnet mask, calculate the subnets that get created. We'll calculate the range of usable addresses and you're going to get plenty of practice in this video series. Not…
