Yet IPv6 hasn’t been adopted. For decades. Because it wasn’t implemented transparently at the OS. I can’t plug in to my ip6 only network and reach an ip4 address because end user OSes don’t implement clat transparently, even today in 2026, let alone 20 years ago.

  I learned recently that France IPv6 adoption is also very high.

  I’m on 4g My v6 endpoint is unreachable. My v4 one is fine.

  Yes you can able to see IPv6 at your browser, but actualy there is always middlewhere sofware level (NLB, ALB, NAT) to reach real backend server, which creates bottle neck. For large scale enterprises this creates issue, even for cloudproviders, I have encountered bottle neck at some Major cloudprovider which causes snowball impact to whole cluster retry mechanisms and 4 hours outage for us and some other customers :D if the 2 enterpise has machine to machine IPv6 connectivity, this is will not happend.

Yet IPv6 hasn’t been adopted. Well over half of Google’s traffic is IPv6 in the USA, and it’s recently become over 50% of all Google’s traffic worldwide at weekends. https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption https://www.google.com/intl/en/ipv6/statistics.html#tab=per-... https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html

> Yet IPv6 hasn’t been adopted. For decades. I'd argue it has, but that's not the point. IPv4 is pretty much mandatory for most users of the internet. Yes, individual users probably neither know nor core whether they're on IPv4 or IPv6, but it's so difficult to run IPv6-only that you just wouldn't bother. Trying to teach someone about how to use ULA vs. GUA only leads to headaches. In fact, I'd go so far as to say the reason why the internet became so ubiquitous was because of NAT -- static internal addressing is pretty much fundamental to an easy-to-use experience. Having multiple addresses on a host only makes things far more confusing, so people don't bother, because IPv4 just works.
