at Arbor Networks, we've been doing this kind of blackhole monitoring
as well, but on an unused, globally-announced class A network:


monitoring an entire /8, you see lots of interesting things, including:

	- constant worm infection attempts (see the paper above)
	- backscatter from victims of source-spoofed DDoS attacks
	- widespread host scans for the vulnerability du jour (FTP,
	  dtspcd, SSH, etc. - you name it, we see it)
	- random Internet flotsam and jetsam i have yet to figure out (!)

if there's enough interest, we might release the software we've
written to capture, reassemble, and characterize this traffic
(tentatively called "MasterBaiter" :-)

if our marketing folks don't kill me first...
