    NAME

    ipcalc - perform simple manipulation of IP addresses
     
    

    SYNOPSIS

    ipcalc [OPTION]... <IP address>[/prefix] [netmask]

     

    DESCRIPTION

    ipcalc provides a simple way to calculate IP information for a host. The various options specify what information ipcalc should display on standard out. Multiple options may be specified. An IP address to operate on must always be specified. Most operations also require a netmask or a CIDR prefix as well.

     

    OPTIONS

    -b, --broadcast
    Display the broadcast address for the given IP address and netmask.

    -h, --hostname
    Display the hostname for the given IP address.

    -m, --netmask
    Calculate the netmask for the given IP address. It assumes that the IP address is in a complete class A, B, or C network. Many networks do not use the default netmasks, in which case an inappropriate value will be returned.

    -p, --prefix
    Show the prefix for the given mask/IP address.

    -n, --network
    Display the network address for the given IP address and netmask.

    -s, --silent
    Don't ever display error messages.
