That would made sense to use just 'ip=<client-ip>' because the ipconfig
tries to make sense of the IP and set netmask and broadcast accordingly 
... (I saw that in earlier versions that for an IP 132.230.4.123 the tool 
used class B netmask even provided with a class C via dhcp - bug fixed 
versions ago ... But this mechanism makes sense for the problem stated 
above ...)
