Christian,
One would hope that 6to4 would put market pressure on ISPs to provide end
users with an entire /48 prefix, rather than just a /128. Unfortunately,
I don't believe that most consumers in the US will care about IPv6, or
even have the option of native IPv6 service until we have reached the
point that standard dialup service will only provide users with private
addresses that are NAT-ed by the ISP itself.
I know of many ISPs, mostly bargain-basement providers, that no longer
give out global addresses, and the situation will likely worsten before
IPv6 becomes popular. I can't wait until AOL-Time-Warner or AT&T Worldnet
start offering reduced rates for those willing to live exclusively with
NAT-ed addresses. (You can't run a server on a private address, so that
virtually guarantees that your reduced-rate users won't cost you much
anyway.) Most people would rather live behind multiple layers of NATs
than pay more for their connectivity. After all, the software will just
work around it, right? -Nathan
