Broadcast Address Calculator

Enter any IP address with a subnet mask or CIDR prefix to instantly calculate the broadcast address for your network. Get the last usable address in your subnet, the network ID, host range, and total addresses — essential for understanding how IPv4 broadcast communication works across your network segments. The wildcard mask calculator converts a subnet mask to its inverse wildcard mask — and vice versa — for Cisco ACL and OSPF statements.
