Anything special with 172.31.0.0/24?

  • From: Pim van Riezen
  • Date: Fri Feb 09 17:58:31 2001 
This sort of stuff really gets me puzzled. Why would anyone use IANA
reserved space for probes, if the path back to respond to these probes
will end up in the drain anyway? And why do I see so many from
172.31.0.0/24? Is this a Wintendo doing 7 bit over ethernet thinking it is
multicasting?:)

I'm wondering if anyone else is seeing more strange traffic from this
particular range and/or has a theory.

Cheers,
Pi
