I'm writing perl application about  creating virtualNic  in  vCenter.  Until now, the virtualNic is generated successfully  and  the mac-address can  be  retrieved,  but  I  have to wait fourty-second  for  the  ip-address  returned.  I  want to know is there any efficient way to  get  ip-address  immediately  after  generating the  virtualNic? Or,  if  there is another way to  allow me  bind  a  newly-generated  ip-address  into the  virtualNic?  thank  you  for  help.
