       If an option is specified ipv4calc calculates the requested element from the address and prints it on
       stdout.

       If multiple options are specified, only the first one is printed.

       If no options are specified, the program prints the host part of the address, the network and the
       broadcast address as deduced from the given address.

       If address doesn't contains a netmask or mask length, the default one is assumed.
