   To quote Maxwell Smart: 'Sorry about that, boss'.   
      
   The capabilities of different XP editions are more fine-grainedly   
   limited than in previous Windowses. My copy is Windows XP Professional,   
   but it is a pretty limited version, though not as bad as Home edition.   
   I checked it once more: There is an alternate IP configuration   
   available, but it cannot be used at the same time as the primary   
   address.   
      
   Technically, an IP alias makes the interface to respond to ARP   
   requests for the alias address in addition to the main address.   
   Also, the sending IP in the IP headers has to be set to match   
   the subnet it is sent to.
