Sometimes the network becomes too large to manage because the network is too crowded. One of the most effective ways to solve this network congestion problem is to break the TCP/IP network into smaller, more manageable blocks.
The practice of partitioning networks is called subnetting and requires an IPv4 subnet calculator tool. Each subnet has an IP address to represent it. These subnets are interconnected by routers. The router needs a network address and subnet mask to find out if the incoming IP packet is routed to any of its subnets. Sometimes, when you have to consider how many subnets different parameters should be and how many hosts should be in the subnet it is difficult to perform network computing first.
This subnet calculator is a handy tool for finding the number of possible subnets for any given network address block. You can choose to combine subnets and hosts, the number of subnets that fit your network, and the host address range of broadcast addresses for any given subnet mask.
