an anecdote for which I don't have much evidence.

I started noticing repeated ICMP Echo Replies after a change in
our local network.  Now, I'm not 100% certain that we weren't getting
them before this change, but I was surprised to see them happening
afterward.

The change?  The campus backbone is an Ungermann Bass broadband
system.  We were using UB buffered repeaters to attach our local net a
channel on the broadband.  But the campus is converting to using the
Chipcom Ethermodem III with Lanbridge 100.  Our local net has Sun 3's,
a Sequent, uVaxII's with DELQA's and a variety of uVax workstations,
and some 3b2's and 3b1's.  There may be some mismatching of ethernet
versions in there like Phil suggested.
