Dumb question, but my understanding was that ipv6 is not backwards compatible with ipv4. So all devices within Vietnam will be able to talk to each other, but how will they talk to the outside world?
Ipv4 is not even ipv4 compatible. You use nat to translate one type of ipv4 into another to talk on the internet. Ipv6 is using nat in the same way.
The problem is that ipv4 is not forward compatible ( naturally ). So ipv6 can talk to both, ipv4 only to ipv4.

There are ways to translate IPv6 to IPv4 so users can still access legacy sites.
