You'd happily deploy a website for use by the general public on IPv6-only?

[simoncion]

I use Devouring Goats on your straw man. It's Super Effective!

To be less glib: IPv6 is well-adopted. It's not universally adopted.

[billpg]

Until you would happily deploy a service on IPv6 only, I suggest that you're still dependent on IPv4.

[simoncion]

I'll repeat myself:

  IPv6 is well-adopted. It's not universally adopted.

[massysett]

No. Which doesn’t prove the technology has not been adopted. The internet also consists of much more than public-facing websites. So what’s your point?

[billpg]

My point is that we're still dependent on IPv4. For all the progress IPv6 has made, no-one is willing to switch IPv4 off yet. Until we do, we're still constrained by all the problems IPv4 has.

[Dagger2]

Plenty of people are switching v4 off. Facebook run basically all of their datacenters without v4. T-Mobile USA use only v6 on their network. Thread only supports v6 in the first place

There are plenty of other places doing the same thing, but these examples alone should be sufficient to disprove "no-one is willing to turn v4 off".
