Let's not panic here...
While statements asserting the vastness of the IPv6 address space are completely true, the conclusion that this means IPv6 reputation is impossible completely misses the point. IPv4 reputation tracking techniques would certainly fail to translate directly into IPv6, but why is that the only option? That's like replacing a wood house with a steel-frame house, but building it using exactly the same architectural plans. A different underlying technology gives the opportunity to innovate and establish an environment where carriers can get the IP-based reputation information they need. I’ve got some more thoughts on the topic in a blogpost. Google “MessageSystems blog” if you’re interested.
