Calculate network, host, and broadcast addresses with a dedicated keypad. Supports classful and classless modes, with pickers for subnet mask and prefix length. Includes special-purpose address information based on RFC standards.





This utility calculates IPv4 IP address ranges, host counts, broadcast addresses, and subnet masks. It supports both traditional classful and classless (CIDR) subnet mask calculations for network administrators.




This tool calculates IPv4 and IPv6 subnets, providing detailed information such as the number of hosts, subnet size, class, and network addresses. Use the interactive CIDR slider to dynamically adjust subnet properties.
