Further more, IRC does NOT take that much bandwidth, there is a myth that efnet NEEDS OC3 links etc because of the traffic that is passed across it, what people dont say is that the servers actually only run at between 1 and 2 megabit/second if you remove the traffic from DDOS and attacks like smurf.
I have a question: given that half the bandwidth and almost all of the spike bandwidth is devoted to smurfing, why don't IRC servers just block multicast ping? I mean, okay, so it's in the kernel code instead of being a separate application. It still shouldn't be hard to come up with a patch that killed smurfing. Pings should never be forwarded to multiple hosts. Bear
