   If, in the unlikely but plausible event of multiple IP subnets sharing   
   the same broadcast domain, one sends to 255.255.255.255 it will be   
   accepted by hosts in all the disparate IP subnets sharing that   
   broadcast domain yes?  That being the case, if one wanted to make sure   
   that only hosts in the same IP subnet receive the broadcast, one   
   should use the subnet-local/directed broadcast address.   
      
   Is that perhaps one of the reasons that ifconfig tends to report the   
   subnet-specific/directed broadcast address in its output?
