I mean I’ve been using native dual stack for over a decade and I’m most definitely American. A fun anecdote was I was having issues with clicking on links from Google once and turned out ipv4 was busted but 6 worked fine for half a day. And there really isn’t any turning on ipv6 I get it by default and it’s with the most hated isp Comcast. They’re actually really good about v6 support I’ve not moved off them because of it. It’s literally 10ms faster than 4 lilely due to cgnat.
