IPv6 adoption for ISPs and OTTs are very high (all examples below are from these segments). ISPs have reduced IPv6 to something extremally simplified (cancelled all 1st hop complexity) - it is not IPv6 anymore. OTTs are capable to handle IPv6 enormous complexity. I believe that IPv6 would never win on the Enterprise market despite I have heard examples of adoption (I have heard about a few cases of downgrade too) - the first hop complexity would block it. Hence, I believe that mankind would stay with IPv4 + NAT for many decades on the business side. "IPv6 for people, IPv4 for businesses". IPv6 is a big fail of IETF procedures. But not everything in this world is possible to fix. IMHO: IPv8 would not happen too. May be in the next century and only if new principal requirements would appear. LEO had a chance to be such a driver (to replace IPv6). But LEO carriers decided to hide all complexity below IP level (like 3GPP did). Eduard

I believe Microsoft uses IPv6 internally, at least that’s what I read a long time ago
Plus all the cell phone providers (even the Canadian ones), plus many/some big ISPs, I think I heard ComCast (millions of subscribers) is on IPv6. Plus Asia runs on IPv6, if I heard correctly.
