What does subnetting refer to in networking?

• A. Combining multiple networks into one large network
• B. Dividing an IP network into smaller, more manageable segments called subnets
• C. Creating virtual private networks for secure connections
• D. Enhancing the performance of data transmission

Answer: (B)

Subnetting refers to the process of dividing an existing IP network into smaller, more manageable segments known as subnets. This practice is essential for improving the organization of the network and optimizing its performance. By creating subnets, network administrators can improve security, reduce broadcast traffic, and facilitate better management of network resources. Each subnet can function independently while still being part of the larger parent network. This approach allows for more efficient use of IP address space, enhances the ability to control local traffic, and aids in isolating network issues. Essentially, subnetting helps in creating a hierarchical structure within IP networks, which not only simplifies network management but also supports scalable and organized growth.
