Hi Rick, What I'd be curious to know in the numbers being thrown around if there has been any accounting of transient address usage. Since I'm spending an awful lot of time with DNS these days, I'll actually provide a cite related to that (and not simply suggest you just quote me :-). See sections 3.3.2 and 4.4 of the following: Availability, Usage and Deployment Characteristics of the Domain Name System, Internet Measurement Conference 2004, J. Pang, et. al At some point transient address pools are limited and presumably so are the possible numbers of new bots, particularly within netblocks. Is there any accounting for that? Shouldn't there be? What will the effect of doing that be on the numbers? John
