Subnets divide networks into smaller parts from "summary" of Computer Networking Beginners Guide by Russell Scott
Subnets play a crucial role in network management by breaking down larger networks into smaller, more manageable parts. By dividing a network into subnets, administrators can improve overall performance and efficiency. Each subnet operates as its own network within the larger network, with its own unique address range. This segmentation helps to reduce network congestion and improve data transfer speeds. When a network is divided into subnets, each subnet can have its own set of rules and configurations. This allows for more granular control over network traffic and security settings. For example, administrators can apply different security policies to each subnet based on the specific needs of that part of the network. Subnetting also helps with network scalability. As a network grows, additiona...
