I can't tell if this question is serious. It's either making fun of the embarrassingly inadequate job we have done on this transition out it's naive and ignorant in a genius way. Read the asn32 migration docs for one that migrations like this can be properly done. This was harder but not impossible. We just chose badly for decades and now we have NAT *and* a dumb migration. Oh well. T
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. Mark
