IP Calculator

Note:

ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range.

Note:

Enter your netmask in CIDR notation (/25) or dotted decimal (255.255.255.0). Inverse (wildcard) masks are also recognized. The space in each binary row separates network bits from host bits. Network addresses have all host bits set to zero; broadcast addresses have all host bits set to one, except for /31 and /32 where there is no directed broadcast.

Use IP & CIDR Netmask:192.168.0.1/24
Or IP & Netmask:192.168.0.1 255.255.252.0
Or IP & Wildcard Mask:192.168.0.1 0.0.3.255
