Subnetting

Summary

Subnetting is the practice of dividing a network into smaller logical sub-networks, known as subnets, to improve network efficiency and security.

Detailed Description

Subnetting allows network administrators to create multiple logical networks within a single IP address space by borrowing bits from the host portion of the IP address. It reduces network traffic by ensuring that local traffic is kept within a defined subnet, enhancing performance and security. Each subnet can have its own set of policies and controls, which can be beneficial for managing network traffic and access.
