Trevoke, I won't waist your time with what I think as I agree with the answers here, however, knowing what OS you like to use, I think it could be a neat idea if you set up a machine to sniff traffic and see where this stuff comes in from.

Could be a fun little project for you. I used to do something similar at my college: I would set up my laptop on the network, open up iptraf, watch, then open up wireshark if I wanted a GUI, and kind of watch what was going on.

It's amazing what an expensive firewall used by a college will let in heh.
