IPv4 Wildcard Calculator
This subnet calculator takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values.
Use IP & CIDR Netmask: | 10.0.0.1/22 |
Or IP & Netmask: | 10.0.0.1 255.255.252.0 |
Or IP & Wildcard Mask: | 10.0.0.1 0.0.3.255 |
