subnet

Divided network portion

A subnet, short for subnetwork, is a logical subdivision of a larger computer network.

Network administrators create subnets to organize traffic, improve security, and make large networks more manageable by breaking them into smaller, self-contained segments.

Each subnet has its own range of IP addresses and can communicate with other subnets through routers.

The IT department placed all the printers on a separate subnet.
