Episode 52: IPv4 Subnetting — The Process Step by Step
This episode walks you through IPv4 subnetting as a step-by-step procedure that turns theory into practice. We review how to analyze IP addresses and subnet masks, how to identify valid subnets, calculate host ranges, and determine network and broadcast addresses. Whether you’re creating subnets for departments or segmenting your infrastructure for security and performance, this process is critical to effective network design.
We break down each part of the calculation using examples and simple logic so you can build confidence through repetition. You'll also learn shortcuts that help speed up subnetting decisions during the exam. By mastering this process, you'll be well-prepared to tackle subnetting questions and plan address spaces that scale with your network.
