About Subnet Calculation
Subnet calculation helps you understand how IP networks are divided into smaller segments. This tool calculates network addresses, broadcast addresses, host ranges, and provides binary representations to help you understand subnetting concepts.
You can input subnet masks in either dotted decimal notation (255.255.255.0) or CIDR notation (/24). The calculator supports all valid IPv4 subnet masks and provides comprehensive information about your network configuration.
