Users What is a Subnet? A subnet, or subnetwork, is a segmented piece of a larger network. It allows for the efficient organization and management of IP addresses within a network. Subnetting involves dividing a larger network into smaller, manageable sub-networks, which can help improve performance, security, and overall organization. Subnetting is primarily accomplished through the use of a subnet mask, which defines the range of IP addresses that belong to a specific subnet. The subnet mask separates the network portion of an IP address from the host portion, allowing for efficient routing and management.
