Subnetting Calculation
What is subnetting? ISPs allocate IP address ranges to organizations based on the potential number of networks and hosts, or endpoints, that organizations require. Today, the allocations follow the Classless Inter-Domain Routing (CIDR) assignment method. The organization then subdivides the allocated address space into smaller allocations for each subnetwork within the organization, using a process called subnetting. The result of subnetting is the number of subnetworks increases, while the number of usable host IP addresses decreases. Each subnetwork is known as an IP subnet. Why use subnetting? Subnetting enables assigned network addresses to be broken into smaller, efficient allocations that are more suitable for each network within the organization. For example, a point-to-point WAN link between two routers only needs two addresses, while a LAN segment may need to support many hosts, such as servers, workstations, laptops and Wi-Fi-connected mobile devices.
