In today’s interconnected world, where countless devices rely on efficient communication over networks, managing IP addresses becomes increasingly critical. One essential concept in networking that aids in the management of these addresses is subnetting. But what exactly is subnetting, and why is it so crucial in network administration? More importantly, how can we break down a large network into smaller, manageable parts, known as subnets? In this article, we’ll dive into the techniques of subnetting, explore its practical applications, and walk through detailed examples to understand how subnetting can optimize network efficiency.
