When you run something larger than a toy network, you dont prick yourself in the foot in a pin, even if it blows a big hole in the other guys foot. Too many "other guys", and its your only pair of feet. > Strangely enough, the bulk of spam comes from some very small > part of the address space. Strangely enough, you also seem to think Yeah. Problem is separating it from legitimate email coming from that same corner of the net. If I could firewall out say 61/8 I'd get rid of a ton of spam. And also get rid of a ton of legit email as well. And how distributed IS the spam? Quite a lot actually, with some obvious spikes from sources. Rather more distributed than I'd feel comfortable with supporting your assertion. Here's by AS 4134 (Chinanet) 7.61% 4837 (China Netcom) 5.05% 4766 (Korea) 4.22% 6147 (Telefonica Peru) 2.34% and then various others (TDE Spain, TPNet Poland, TTNet Turkey, Verizon, AtHome Benelux, Servint, Proxad DSL, etc) having 1 to 2 percent each Countrywise - US 25.85%, China 17.68%, Korea 6.73%, Russia 3.83%, Poland 3.61%, France 3.12%, Spain 3.04%, and then Romania, HKG, India, Japan, Taiwan, the UK etc falling between 1 to 2 percent. srs
