How it works
Calculate IP subnets and visually understand CIDR masks directly in your browser.
Enter an IP address and a CIDR prefix (e.g., /24). The tool immediately calculates the network address, usable host addresses, broadcast address, and wildcard mask. Additionally, a 32-bit grid visualizes the division into network and host bits, making subnets easy to understand.
Processing happens entirely locally in your browser.
