I too am seeing this type of traffic. I am seeing it coming from 128.83.166.35 and sweeping across one of my IP ranges. This IP resolves to the University of Texas at Austin. Seems t be coming out of the universities, but does anyone know what it is yet?

I had 1702 hits in one tarpit, let me see if they're still stuck... nope, but they should have been reported to DShield... yes!

source port = 13000, dest port = 13000

Source: 128.59.52.11 = mrl-sgi.mech.columbia.edu

Ended about 21:59 (UTC? Not sure what DShield reports)
