Oh, I see. But one thing I do not understand, it doesn't seem like this
traffic is directed at me, since it's not my address that's the
destination...? Are they routing their traffic through me or something?

OK. I tried nmap -O 188.8.131.52 but got nothing. I have found that
they are running IIS on their web server though. And I can't find any
hosts in that company's netblock.

OK. Very little there... It is not very detailed, since I'm using -P, is
that a Bad Idea?
This is what it says:
Chain INPUT (policy DROP 157K packets, 10M bytes)
That's still nowhere near the total amount of data I've been getting.
There's of course a lot more, but nothing that seems relevant.
BTW, would I have anything to loose by going
iptables -I INPUT -i eth0 -s 184.108.40.206 -j REJECT

Hm, OK, but I need to feel a little more certain about what's going
on... Given I find no signs that the machine is actually up, and that I
still don't understand the traffic pattern,

Well, it is more the time I've been wasting, I spent almost two full
days, in a very critical period... But I do not expect to be charged
for the bandwidth, no...
