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.

Display help usage
Don't display ANSI color codes
Suppress the bitwise output
Just print bit-count-mask of given address
Display results as HTML
Print Version
Split into networks of size n1, n2, n3
Deaggregate address range

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
