Subnetting is a process of dividing a larger network into smaller sub-networks. Each sub-network is known as a subnet and has its own unique IP address range. A subnet can be divided into multiple subnets by further dividing the original network into smaller segments. This is done to increase the network’s efficiency and security, as well as to improve network performance.
It is used in networks where administrative control is required over different aspects of a large network. For example, subnetting is often used in corporate networks to separate users with different levels of access and privileges. Network administrators may also use subnetting to divide traffic among several devices or to isolate a particular segment of the network from the rest.
It is also a useful tool for optimizing a network’s routing, as it allows multiple pathways to be used instead of relying on one single pathway. Subnets can also provide improved fault-tolerance, making it easier to isolate and diagnose problems in the network.
Subnets are differentiated by the inclusion of IP addresses assigned to each subnet. By dividing the IP address range into smaller blocks, subnetting divides the network into different groups and makes it easier to manage the entire network.
