Which term denotes the logical grouping of IP networks to create a smaller network from a larger one?

• A. Domain
• B. LAN
• C. Subnet
• D. VLAN

Answer: (C)

Subnetting is the process of dividing a larger IP network into smaller, logically defined networks by using a subnet mask. This creates subnets, each with its own network address, which helps manage address space and improves routing between different parts of a larger network. For example, taking a single 192.168.0.0/16 network and applying a 255.255.255.0 mask yields multiple smaller /24 subnets like 192.168.0.0/24 and 192.168.1.0/24. While a VLAN groups devices to control broadcast domains at Layer 2, and a domain is an administrative or DNS namespace, the term that denotes the logical grouping of IP networks to create a smaller network from a larger one is a subnet.
