NAME¶
ipcalc - An IPv4 Netmask/broadcast/etc calculator
SYNOPSIS¶
ipcalc [options] ADDRESS[[/]NETMASK] [NETMASK]
DESCRIPTION¶
ipcalc takes an IPv4 address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design sub- and supernetworks. It is also intended to be a teaching tool and presents the results as easy-to-understand binary values.

EXAMPLES¶
ipcalc 192.168.0.1/24
ipcalc 192.168.0.1/255.255.128.0
ipcalc 192.168.0.1 255.255.128.0 255.255.192.0
ipcalc 192.168.0.1 0.0.63.255
deaggregate address range
ipcalc <ADDRESS1> - <ADDRESS2>
split network to subnets where a b c fits in
ipcalc <ADDRESS>/<NETMASK> -s a b
c
