You don’t necessarily have to carry IPv4 across your network with all the
complexities involved in that. You can do IPv4 at the edges with all IPv6
in the middle through a variety of techniques which are relatively trivial
to implement these days.

Hopefully this idea that “you need to do IPv4 anyhow” will die some day soon.

Unfortunately, nobody wants to lead because it comes with certain negative
commercial implications. Perverse incentives remain a problem.

The race is on:

	Will we get IPv6 deployed before our similar failures with regard
	to climate change (for amusingly similar perverse incentive reasons)
	render the planet uninhabitable?
