Episode 14 — Networking & Protocols II: Addressing and Subnets

Understanding IP addressing and subnetting isn’t just a math exercise—it’s a gateway to real security visibility. This episode explains how IP addressing organizes networks, assigns identity, and defines reachability. You’ll learn how subnet masks determine communication boundaries and why those boundaries form the foundation of both routing and access control. The discussion walks through how IPv4 and IPv6 differ, where CIDR notation fits in, and how summarization can simplify large network environments while improving performance and control.Listeners will explore practical subnetting examples that mirror exam scenarios and real operational challenges—segmenting sensitive zones, limiting broadcast domains, and isolating management traffic. The conversation highlights how poor subnet design can expand attack surfaces, enable lateral movement, or complicate monitoring. By mastering addressing schemes and subnet logic, you’ll gain the ability to quickly interpret diagrams, troubleshoot anomalies, and visualize how packets actually flow across trust boundaries.
