The US government is pushing IPv6 for government sites and contractors.

I think there needs to be a push for IPv6-first networks for companies. ISPs in the US are pretty good about IPv6. But network engineers learned IPv4, and don't want to change what works, so companies lag behind. Changing existing networks is hard, but IPv6 is good candidate for new networks. This includes writing docs and eventually the education so IPv6 is the default.
