All the ISP that don't have enough IPv4 want to have more traffic via IPv6 to save resources in their NAT gateways. The entropy of DADDR/SADDR in IPv6 is very low compared to IPv4. Yes there is some traffic, but it looks artificially good because some large content providers happen to have it. For most of the world and people IPv6 continues to be completely immaterial. Very few of my customers care about IPv6 and it is easy to notice when issues are IPv6 only, it takes a long time for them to escalate. Vendors stil ship IPv4 first, or maybe even IPv4 only on some features. And indeed as someone else mentioned, IPv6 is just more addresses. Any other argument is just crusade for good or bad cause, but ultimately crusade which will hurt adoption. Yes IPv6 NAT and NAPT were always going to be a thing and IPv6 ULA is probably still the best alternative for enterprise addressing, unless they happen to have their own globally routable address. We shouldn't try to promote any other changes with IPv6, except more addresses and keep other crusades for another time. Currently we are just helping the incumbents to maintain their oligarchy by insisting nothing is wrong, trajectory is good and it was always intended to be dual-stack for decades. -- ++ytti _______________________________________________ NANOG mailing list https://urldefense.com/v3/__https://lists.nanog.org/archives/list/nanog@list...
