What process allows network administrators to create smaller network addresses from a single network address?

The process that allows network administrators to create smaller network addresses from a single network address is known as subnetting. Subnetting divides a larger network into smaller, more manageable sub-networks or subnets. This is useful for several reasons, including improved network performance, better organization, and enhanced security.

By using subnetting, an organization can effectively allocate its IP address space, allowing for more efficient utilization of addresses and minimizing waste. Each subnet can operate independently while still being part of the larger overall network, which can facilitate easier management and troubleshooting.

In practice, subnetting involves using a subnet mask to identify the network and host portions of an IP address. This allows the network to support multiple smaller networks, each with its own range of addresses. This greater control over network traffic and organization can help improve security and performance within the network infrastructure.
