The sad thing about this is that there are parts of the Internet that aren't
subnet'ed properly. My mail server happens to be in the same /16 as about
two hundred entirely different locations, so whenever someone gets one of
those from whatever lamer in some shithole 900km away from me, my IPs get
blocked as well. Our NOC, collateral damage, and life in general for that
matter, suck. :)
