Who is going to be my 6RD endpoint when 6to4 is deprecated? My ISP does not provide 6RD. I don't know if ny DOCSIS modem is compatible with 6RD, and I know for sure that my CPE does not implement 6RD. 6RD is NOT an alternative to 6to4. 6RD is an alternative to native IPv6 for access networks. To put it another way, 6to4 is deployed by end sites, whereas 6RD is deployed by access providers.I agree with Remi, 6RD isn't a functionally equivalent alternative to 6to4.
The most important difference is that 6RD forcing to the provider to provision their own relay.
Here in .au ADSL routers are owned by the customer, not managed by the ISP, so deploying IPv6 via 6RD is unfortunately not an option.
As most of the case in the world. Usually the DSL modem owned by the provider, but not the router. But there are some countries you can own your own DSL modem. In the DOCSIS architecture the cable modem, always owned by the provider, potentially can be made more smart to support 6RD, however most of the user already installed dumb soho router without ipv6 support.
