As long as I was at it, I decided to look at what a large collection
of diverse machines did with pings to .255. I hit our backbone
ethernet (128.146.8, a little over 100 hosts) with a ping like this,
and the results are:
Responding with 184.108.40.206:
Sun-3/180 (SunOS 3.5.1 [UNIX]).
Responding with their own addresses:
HP-9000 (HP-UX [UNIX]), IBM-RT/PC (Mach), Proteon P4200, BBN Butterfly
(Mach), Pyramid (OSx 4.x [UNIX]), Encore Annex telnet server.
DEC-2060 (TOPS 6.1; responds to direct ping), AT&T 3B2/400 (SysV
Rel3.0 + TWG WIN; responds to direct ping), Kinetics Mac gateways
(KIP; doesn't respond to direct ping), Encore Multimax (Umax 4.2;
responds to direct ping), TI Explorer (Zetalisp; responds to direct
ping), Xerox-1108 (Interlisp; responds to direct ping).
Also, we have one HP-9000 client subnet. When pinging that subnet's
broadcast addr (220.127.116.11), *only the server* responded - the
rest were silent. Weird.
