-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
