Hey,
One of my machines just got probed by a set of IPs
during the same _TCP_ probe, one of which is an illegal
192.168.1.*
My understanding was that 192.168.1.* addresses wouldn't
be routable, and that having the probe alternate IPs
also concerns me.
So I wonder what kind of danger there might be here.
Could this be some kind of "stealth" probe. What good
would it do a scanner to alternate IP's ? Is the
192.168.1.* some sort of primer?
Someone please enlighten me as this challenges my knowledge
of IP networking.
Thanks,
Joshua
