Episode 19: Subnetting — Concepts and Purpose
Subnetting allows you to divide larger networks into smaller, manageable segments. In this episode, we explain why subnetting is important, how it improves network efficiency, and how to visualize IP ranges. You’ll learn key terms like network ID, broadcast address, and usable host range, and how subnet masks control address grouping.
We also prepare you for the calculations involved in subnetting, which will be covered in future episodes. Whether you’re brand new to subnetting or need a refresher, this conceptual foundation is critical for success on the exam and in the real world.
