   All the SunOS (pre-Solaris) that I ever used defaulted to the 0   
   broadcast address. As I understand it, for some years it was more usual   
   to run Suns on their own network, or at least their own subnet, such   
   that they could run that way.   
      
   We always put the right broadcast address on the ifconfig line,   
   especially as we usually had non-Sun machines on the same net.   
      
   As well as I know it, after using SunOS, I always put -broadcast on my   
   FreeBSD machines ifconfig, and probably on others, too.
