CIDR Subnet Calculator

Calculate subnets easily: 1. Enter the IP address and CIDR prefix (e.g., 192.168.1.0/24) in the input box. 2. Click 'Calculate'. 3. The tool will display detailed network information, including the subnet mask, network address, broadcast address, and the range of usable host IP addresses.

This tool performs CIDR (Classless Inter-Domain Routing) calculations locally in your browser. It uses bitwise operations to determine network boundaries and host ranges from the provided IP and prefix, ensuring all data remains private.
