Once promoted as a way to give every internet device you would like a reachable external IP … has instead been a new protocol locked behind giant corporations and telecoms. Now mobile providers and some ISP play gatekeeper … don’t allow you to keep any IPv6 devices (rotate assignments) so we end up with little benefit to the end consumer.
The idea that a home user ca setup a desktop and share anything I want via IPV6 another person without the need for a middle man “cloud” provider just didn’t happen. In fact requesting blocks of IPv6 is not easy … and at the end of the day for the average user who cares.
Great so Verizon can now assign my phone and IPv6 address… that I can literally do nothing with.
Corporate greed / government control have severely limited any usefulness of IPv6 at least here in the US
