I've observed IPv6 hitting a plateau (even a slight decrease!) in usage of IPv6 across multiple large networks measured over significant time. A publicly accessible graphs produced from the AMS-IX platform is available here: https://stats.ams-ix.net/sflow/ether_type.html IPv4 vs IPv6 is neatly normalized by presenting the traffic as a percentage rather than some absolute measure. I'm attempting to collect information from other platforms as well because I think this type of graph helps compare apples to apples. Growth of IPv6 traffic in absolute units is expected, if we consider IPv6 traffic usage a function of overall Internet traffic usage. Internet traffic appears to grow steadily. However, if IPv4 and IPv6 grow at the same rate, my interpretation would be that IPv4 use is not declining, thus IPv6 isn't growing, and we should indeed be discussing the current failing of IPv6. Some may argue that IPv6 traffic doesn't replace IPv4 traffic, that IPv6 traffic is new apps or new demand, but in a Happy Eyeballs / dualstack / nat64 world I'd consider that somewhat unlikely. Happy to hear other people's thoughts! Kind regards, Job ps. Before we venture into a tit-for-tat where we trade pictures of decline (e.g. IXP stats) against pictures of growth (google stats), I'd like to learn more why we see what we see in the current decline graphs.
