In networking, what is the main purpose of subnetting?

• A. To increase security
• B. To improve performance
• C. To manage IP address allocation efficiently
• D. To enable faster data transfer rates

Answer: (C)

The main purpose of subnetting is to manage IP address allocation efficiently. Subnetting divides a larger network into smaller, more manageable sub-networks, or subnets. This allows network administrators to efficiently allocate IP addresses based on the specific needs of each subnet, ensuring optimal use of available address space. By using subnetting, organizations can reduce wastage of IP addresses and enhance routing efficiency. Each subnet can function independently, allowing for better traffic management and easier implementation of policies specific to certain segments of a larger network. This structured approach to IP address management helps maintain organization and scalability as networks grow. While subnetting may improve security by isolating subnets from one another and aid in performance by reducing broadcast traffic within each subnet, its primary function is to manage the allocation and organization of IP addresses effectively. Thus, the choice that emphasizes efficient IP address management captures the core advantage of subnetting.
