I’ve always struggled with how subnetting is taught. Most explanations rely on binary math, but what students actually need is spatial intuition. So I built Networking Tetris, an interactive tool that visualizes VLSM subnetting as blocks inside a network. It enforces subnet boundaries and lets students experiment visually.
