IPv4 subnet calculator
Parse your IPv4 CIDR blocks and get all the info you need about your subnet
Note: This tool calculates IPv4 subnet information from CIDR notation. Enter an IP address with or without a subnet mask (e.g., 192.168.1.0/24 or 192.168.1.0). The tool will compute the network address, broadcast address, usable IP range, subnet mask, wildcard mask, and more. Use the Previous/Next block buttons to navigate between adjacent subnets.
