Understanding IP Subnetting
Subnetting is the process of dividing a single large network into multiple smaller, more manageable networks, or subnets. This calculator helps network administrators and students understand the properties of a given subnet. By providing an IP address and a subnet mask (in CIDR notation), it calculates key information such as the network address, broadcast address, range of usable IP addresses for hosts, and more.
