When I've had visibility into other large botnets (srizbi, rustock, mega-d), I was consistently seeing a 10 to 1 IPs-to-unique-bots count over a time period of a week. Happy to make the raw pcap data available to anyone who is curious. The UCSB guys showed similar results in their excellent Torpig paper. http://www.cs.ucsb.edu/~seclab/projects/torpig/torpig.pdf

First, Alex, don't you know all security people are 100% secretive? :)
Back on topic, there is good data out there showing far, far more than 1 million hosts on the Internet infected. Hrmm, my first two Google searches did not turn anything up. So maybe those security guys are being secretive!
