If you have a network 172.16.0.0/16, then 172.16.255.255 is accepted as a broadcast address, but 172.16.0.0 is not. Diskless Sun machines attempt to use the latter, so the broadcasts get ignored. The change is older than I thought though. The code was #ifdef'd out back in Dec 1995 in v1.33 of sys/netinet/ip_input.c, and was removed completely in v1.48 (Oct 1996).
