Understanding Subnetting: Benefits, Techniques and Best Practices

• Subnetting involves dividing a larger network into smaller subnetworks (subnets) to improve network performance and security.
• IP addressing and subnet masks are essential components of subnetting.
• An IP address is a unique identifier assigned to each device on a network.
• A subnet mask is used to divide an IP address into network and host portions.
• Subnetting provides benefits such as reducing network congestion, increasing efficiency, and improving security.
• Techniques such as Variable Length Subnet Masking (VLSM) and Classless Inter-Domain Routing (CIDR) can be used for subnetting.
• Best practices for subnetting include proper network topology design, appropriate subnet mask selection, and careful IP address assignment.
• Subnetting maximizes IP addressing efficiency and extends the life of IPV4.
• It reduces network traffic by eliminating collision and broadcast traffic and improves overall performance.
• Subnetting allows for the application of network security policies at the interconnection between subnets.
• Subnetting facilitates spanning of large geographical distances and helps to allocate IP addresses that prevent large numbers of unused addresses.
• Subnets are usually set up geographically for specific offices or teams within a business, allowing their network traffic to stay within the location.
