   I don't see why that would be a restriction. The subnet is 64 bits. Dividing   
   the host part of the address in four 16 bits parts is just a notation   
   convention. Having the lower 16 bit set to zero is no different from having   
   the lower 8 bits or the lower 18 bits set to zero. Or just the last bit.   
      
   As long as you do not set all the lower 64 bits to zero...   
      
   Just try it when you have IPv6 back...   
      
      
   Cheers, Michiel
