This isn=E2=80=99t really a giant set of naysayers IMHO, but there is =
enough embedded logic in devices that it doesn=E2=80=99t make that much =
sense.

Either you can survive with some type of NAT or you can=E2=80=99t.  Many =
of my devices would not be missing capabilities if I had just IPv6 on =
them with some gateway to reach the IPv4 internet.  I could likely make =
a short list of the sites that I really need access to that are IPv4 =
only.  With Amazon/Walmart day, they would be well suited to have a fast =
IPv6 site :)

It=E2=80=99s just a few operating systems that need to be changed:

windows
linux
various *bsd flavors
macos

I don=E2=80=99t think it=E2=80=99s impossible, but so many things check =
for  224 > A > 1 it would be a large bit of work to fix those.  This is =
excluding the routing equipment.

What i=E2=80=99ve learned is that stuff like the netgear/linksys you =
have at your house spends around ~6 months in the supply chain before it =
reaches you.  these all need to be updated as well as the =E2=80=9Cbig =
iron=E2=80=9D stuff like cisco/juniper/arista as well as their embedded =
OS underneath, so maybe QNX or something else =E2=80=98odd=E2=80=99.

That effort would need to have everyone moving in the same direction now =
which seems unlikely.
