That sounds like only using 6to4 addresses until the entire internet
supports IPv6. Unfortunately there were NEVER enough IPv4 addresses
to actually do that. We were effectively out of IPv4 addresses
before we started.
Add to that no one wanted to run 6to4 relays. For the asn32 strategy
to work every IPv6 capable router needed to be a 6to4 relay and to
perform encapsulation / decapsulation depending upon whether the
next hop supported IPv6 or not.
