This seems like a good place to ask--I'm on Time Warner. I have an ipv6 address, and can get to ipv6.google.com, so it seems like everything is in place. But all my web browsing (chrome or ff, Windows 7) defaults to use ipv4 everywhere.

Is there something I need to change on my end? I've got pretty vanilla settings. Thanks!

I think it pretty likely that once we reach 50% it will switch from "That thing that techies care about" to "Something people assume everyone has", and that any remaining ISPs that don't provide IPv6 will rush to get it done. I'm sure that IPv4 support will continue for a fair while though.

What's the mechanism that makes that first company drop support for IPv4? Cost? It feels like it'd need to be a dramatic cost saving in order to kick in at 50% adoption.

The inability to get IPv4 space is going to be a big motivator ;-)

Already seeing stuff like that happening in certain asian countries, where companies are only available over IPv6.

Many residential ISPs don't. I'm stuck on Verizon to enable IPv6 on FIOS.

Comcast in San Francisco supports native IPv6 on residential accounts. Even did it (almost) right and include a /60 prefix delegation.

For all the complaints against Comcast's network, they are really on it with IPv6.

80% in 2018 160% in 2019 Apologies for being flippant. Just making the point that you're extrapolating without spending time on the likely shape of that adoption. It seems more likely that this is an S-curve, and that we'll continue to see IPv4 traffic for the next decade, maybe longer.

You give people a lot of credit. I work at a large ISP/Telco, we just got a new Director of "Core/IP"... in the first meeting the new director attended we started talking about IPv6 initiatives and the new Director interrupted us all and said "Wait. What's IPv6?"

(They were serious)

See the graph here: http://www.potaroo.net/tools/ipv4/index.html ARIN is going to run entirely out of IPv4 addresses for general distribution in April of 2015. It's not going to be long before you'll need IPv6 if you want to do anything peer-to-peer.

I thought that was like the Voyager leaving the solar system story that keeps repeating every few years but never seems to actually happen. Only meant partly in jest. When they start to get really rare, the price of IPv4 blocks will keep going up, until some institutional holders of large blocks start selling. It could take quite a long time before it's really gone for good.

Because while it might be a lot of effort for the large institutional holders when they've historically allocated stuff assuming they have the whole huge block, eventually the price-cost trade-off will reach a point where the address space is valuable enough.

Has anyone got any idea what the (relatively) big spike on October 4th 2014 was? A quick google revealed it's not some "World IPV6 day" or something (though there was something like that on 2011 which had a next-to-zero impact). Was there maybe a new phone or console (or an OS update released to either) released?

I would hazard a guess that that was when global routing table hit 512K routes and crashed a few hundred ISP routers worldwide? That might have been earlier in the year though.

The one thing I gather from that graph is that over weekends, IPv6 use spikes. I assume that this means that networks or devices at companies and schools are lagging behind at using IPv6?

In the United States, Comcast is one of the largest ISPs that has deployed IPv6, and they've (purportedly) rolled it out to 100% of their residential customers (with supported CPE). However, they're still working on their IPv6 deployment for business customers (still in trial, availability "any day now"). This could account for a lot of it, especially in the US.
