A subnet calculator is a tool that helps you calculate and determine the details of subnets within a larger network. It can help determine the subnet ID, network address, broadcast address, range of usable IP addresses, and other subnet-related details.

To use a subnet calculator, you typically need to provide the IP address and subnet mask of the network you want to subnet. The calculator then performs calculations to determine the subnets and their associated details.

There are several online subnet calculators available that you can use by entering the necessary information. Additionally, there are also subnet calculator software programs that you can install on your computer for offline use.

Some subnet calculators also provide additional features and options, such as determining the number of hosts per subnet, or the number of subnets that can be created with a given IP address range. These calculators can be useful for network administrators and engineers when planning and configuring network subnets.
