What is a subnet in relation to a local network?

A subnet, short for subnetwork, refers to a segment of a larger network that is created by dividing the network into smaller, manageable pieces. The range of IP addresses assigned to a subnet defines the specific portion of the overall network that can be utilized for devices within that particular subnet. This means that each device connected to the network is assigned an IP address that falls within this defined range, allowing for organized and efficient communication among devices.

When understanding subnets, it's important to consider how they influence network performance and security. By segmenting the network into subnets, administrators can reduce traffic congestion and enhance security through controlled data flow between different network segments.

The correct focus on the range of IP addresses highlights the fundamental aspect of subnets, which is their role in IP address allocation and management within local networks. Understanding a subnet's structure is crucial for network design and troubleshooting, as it directly affects how devices communicate with one another and with external networks.
