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. J. Nagle
