Vax 4.2 UDP Bradcast woes followup..

[jbn at wdl1.UUCP]

      Sites with nontrivial networks should be very careful with broadcast
IP packets.  We have problems with some Masscomp systems that want to broadcast
to every host on our class B network, asking for all of [128.5.xxx.xxx].
This sends to our sites in Michigan, California, Colorado, and Texas, clogging
the long-haul lines with ``rwho'' packets.  
      4.xBSD needs to know about subnets.  More on this later.
