If we could recover all IP addresses that are not in use now (especially from those who got a /8) we would breath some air, given that ipv6 is basically not happening.

How is IPv6 not happening? Google shows pretty good growth: https://www.google.com/intl/en/ipv6/statistics.html

It's interesting that the number fluctuates so much every weekend. I guess it's caused by people accessing the Internet from home instead of from the office. It's more than I expected.

I've been seeing more and more pressure to support IPv6 in the various SaaS companies I've worked at. I do think it's happening.

That said I tend to think LANs and VPCs will continue to use IPv4 internally for decades even if the load balancer does IPv6.

I'm at a home connection from a normal provider on brasil (third world country) and my router assigns a public ipv6 for each connection. I think all big providers have ipv6 enabled by default over here.

Do they also provide an IPv4 address? If not, have you run into any problems with sites that don't yet support IPv6?

At what share of deployment would you consider v6 as happening — 10%? 20%? 40%? 60%? 80%? 90? Or would you require even more than 100% of the people who have v4 access?

When it becomes viable to market IPv6-only home connections.

Sounds like 99-100% then

It's already viable to supply IPv6 only mobile with NAT64 (see T-Mobile US). I'm aware that many residential ISPs are putting everybody behind CGNAT; and there's some amount of push towards LTE for residential internet, so I suspect IPv6 with a transition mechanism is already viable for home connections.

Anyway, given the number of people who have effectively no choice in home connections, what are we going to do when the incumbent provides us with IPv6 only? LTE or Satellite is going to be even less likely to give me a real IPv4 address.

That's exciting then, because that's already happening! ;)

It's used widely in meshnets.
