Or create some cutting edge application that will work only on ipv6
I know ipv4 users like author mentioned will still be able to access them because someone else will plug in. We are stuck with ipv4 for decades, aren't we?
This was always going to be the case, even with more speedy adoption op IPv6. It's also not really a problem.
Making services just available for IPv6 is going to be a recipe for disaster of the service, you've now made the service unavailable for 80-90% of your audience, and they can't do a thing to fix it (their ISP has to). You need to be better than start-up-era Google, Facebook, YouTube or Netflix to push through that and force ISPs to adopt IPv6 to support you. Basically impossible.
Forced adoption is a much better model. Apple forcing iOS apps to work on only IPv6 connections if they want to get into the app store probably is one of the largest drivers of adoption by businesses small and large, and IaaS providers especially.
51% in the USA.
Still too many to make it practical, but getting there.
To give you some idea of the time frame: Windows XP uses privacy addresses.
Probably. All the IPv4 only devices being made now aren't going to get IPv6 and they don't have the capacitor plague or junky lead free solder of the early 2000s to kill them. They'll probably live a long life, or at least until 2038.
