-s, --source address[/mask]
Source specification. Address can be ... a network IP address (with
/mask), ... The mask can be either a network mask or a plain number,
specifying the number of 1's at the left side of the network mask.
Thus, a mask of 24 is equivalent to 255.255.255.0. ...
Make your own mask ... http://jodies.de/ipcalc
