IP Subnet Calculator
Enter any IP address along with a subnet mask to calculate complete network details including the network address, broadcast address, first and last usable hosts, and available host range. Get instant results with CIDR notation, wildcard mask, and total address count for precise IPv4 subnet analysis. The subnet mask tool handles forward conversion (CIDR to mask) and reverse lookup (host count to optimal prefix) in one interface.
