First of all, the idea of my washing machine having a globally routable addess is a little scary. Someone could hack in and ruin my delicates.
Second, in terms of waste, I understand what you are talking about when you bring up the old "640K" arguement. I remember reading an article 10 years ago saying that the 486 processor would never see the desktop, because it was too powerful for anything other than servers. However, 128 bits *is* alot, enough that you could take all the publicly routed IPv4 addresses, and assign all of them to each square meter of the Earth's surface. Each square meter (and that includes water) could be assigned a full 2^32 address space. Until we start talking about extraterrestrial internets, I think that 128 bit will do. Third, I agree that summarization is a good idea. But how should it be implemented? I would think geographically. However, from my personally experience, that wouldn't work out the best. I've been in a office building in Minnesota and tracerouted a machine on another floor in the same building. The path went from Mpls, to Chicago, to St. Louis and back. Any intelligent summarization will have to be based on the telecommunication providers rather than geography. Then you have issues of teleco moving, merging, failing, reconfiguring, etc. I don't know that there is a good permenent solution.
