We had several notices this week with non-assigned addresses which are
completely unroutable on our network. They're obviously spoofed, and
probably spoofed off-campus due to our anti-spoofing mechanisms.
It presents an interesting problem for those of us processing take down
notices. If these few are tainted, how many in the past, or near
future, will be tainted by spoofed addresses?
