loosely) gets you to an infinitesimal amount of content on the
Internet. The content most people want is available via IPv4 and
there is no incentive for content providers to spend the money to
change this. At best, I suspect that within 5 years you might see
IPv6 as an intra-ISP infrastructure through which you tunnel NAT'd
IPv4. In other words, the IPv4 address becomes a non-unique
identifier over an infrastructure that uses IPv6 addresses as locators
(with those locators numbering NAT devices (ITRs and ETRs if you
