How It Works
Calculate subnet details including network address, broadcast address, and host range from an IP address and CIDR mask.
An IP subnet calculator performs network calculations for IPv4 addresses using CIDR notation. It computes the network address, broadcast address, usable host range, subnet mask in dotted decimal, and total number of hosts per subnet. The prefix length (e.g., /24) specifies how many bits belong to the network portion. Higher prefix values mean smaller subnets with fewer hosts.
