Not sure, but you actually entered in here to a subthread of the
original conversation, this one about other possible ways of dealing
with black hole "ICMP-munchers" in a pre-emptive fashion. I had a
brainstorm that I thought would be workable, which is what we were
discussing here. Apparently, it turns out my idea was no good. ;-)
The original discussion about MS blocking ICMP to their own servers,
which is the discussion it sounds like you are looking for, is over
that-a-way... *points*
