Why is Subnet Mask Size Crucial in Network Subnetting?

Answer: Subnet mask size is important in network subnetting as it determines IP address allocation and defines network boundaries for better management, security, and routing optimization.

Below are the reasons specify why the subnet mask size is important in network subnetting.

Address Allocation

The subnet mask actually determines the size of the subnet and also how many IP addresses are available within that subtext. If we choose the correct subnet mask size, then the proper allocation of IP addresses can be done.

Network Segmentation

The subnetting process allows the logical segmentation of a larger network into the smaller sub networks. These subnet mask delineates the boundaries of each subnet by allowing better network management.

Broadcast Domain Management

Subletting limits the size of broadcast domain within the network. A smaller subnet mask size creates the smaller broadcast domains, which actually reduces the network congestion and broadcast traffic.

Routing Efficiency

By applying the subnetting there is improvement in routing efficiency as their is breakdown of a larger network into smaller subnets. This allows routers to make more accurate routing decisions based on the subnet info.

Security Enhancement

The subnetting process also improves the network security by allowing administrators to implement access controls, firewall rules, and security policies at the subnet level.
