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 su‐
   pernetworks. It is also intended to be a teaching tool and presents the results as easy-to-understand binary values.

   --help Display help usage

   -n, --nocolor
          Don't display ANSI color codes

   -b, --nobinary
          Suppress the bitwise output

   -c, --class
          Just print bit-count-mask of given address

   -h, --html
          Display results as HTML

   -v, --version
          Print Version

   -s, --split n1 n2 n3.
          Split into networks of size n1, n2, n3

   -r, --range
          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
