I don’t believe most providers are intending to offer 6to4 as a global service.  Even the large providers (eg:

legacy things, this is one that should end.  The networks and devices today no longer require this sort of transition 
technology, and the networks where it’s left won’t want it as it will be used for various bad things(tm).
At some point it transitions from being a legacy transition tool which
you really shouldn't be using to being an attractive nuisance, or worse
genuinely dangerous either for the sender or the receiver. personally I
think we've crossed that point and we have a responsibility to insure
proper burial.
