IPv4 Subnet Calculator
Calculate CIDR netmask, network address, broadcast address, usable host IP range, and wildcard masks for any IPv4 address.
How to Use IPv4 Subnet Calculator
A precision IPv4 CIDR subnetting tool for network engineers and system administrators. Enter an IP address and CIDR prefix (e.g., /24, /27) to calculate network address, broadcast address, first and last usable host IP, total hosts, subnet mask, and wildcard mask.
Enter IP address
Input any valid IPv4 address (e.g., 192.168.1.100).
Select CIDR prefix
