Naturally, 6to4 functionality must remain for a while to interoperability reasons, so their resources would be available to the IPv6 world for time to come.

The big providers will not be deprecating their IPv4 addresses until there is no longer a significant IPv4 internet.

At that time, smaller providers could probably get them, but, they will need IPv6 in order to talk to most of the
world.
