The Online Wildcard Mask Calculator is a tool used to determine the wildcard mask for a given IP address/subnet. Wildcard masks are primarily used in Access Control Lists (ACLs) and routing protocols such as OSPF (Open Shortest Path First).
Enter your IPv4 address and the wildcard subnet mask to calculate the matching networks and IP addresses.
