Most consumer ISPs still do not support native IPv6 (at least here in Canada, pretty sure it's about the same in the US). OS support is one thing, but actually having network access is another.

at least here in Canada, pretty sure it's about the same in the US).

We're getting there. TWC is one of the largest ISP's in the US, IIRC, and they have said they have IPv6 support for about 90% of their residential network. Anecdotally, I started getting an IPv6 address from DHCP on my cable-modem connection about 2 months ago.

We're a long way from full IPv6 coverage, but now you finally start to get the sense that it's real, whereas in the past (even a year ago) it was easy to wonder if the ISPs and what-not were even really trying.

>90% of their residential network

I'd like to see where that number is coming from. I've been a TWC subscriber for 9 years, I currently subscribe to their fastest residential offering in my region as well as one of their commercial offerings in the same region.

Both modems are DOCSIS 3 and IPv6 capable, neither receive IPv6 addresses. I have an AICCU tunnel setup on my residential, though it only gets a fraction of the potential performance. (Rather annoyingly the tunnel's routing is also far from perfect: for e.g I can't reach Netflix via IPv6; but because the DNS resolves it doesn't attempt to downgrade to IPv4.)

Considering I'm only 2 hops from their Chicago POP I sincerely doubt they have anything approaching 90% IPv6 rollout.

I'd like to see where that number is coming from.

I don't know how they arrive at it, or how accurate it is, but here's what they claim:

    Time Warner Cable was an inaugural participant in World IPv6 Launch.  
    TWC has rolled out IPv6 to over 90% of its residential network.

Both modems are DOCSIS 3 and IPv6 capable, neither receive IPv6 addresses.

FWIW, I have a relatively new Netgear router (as in, about a year old, maybe less) but even after TWC upgraded my cable modem to one of the newest ones, I still did not get an IPv6 address until I updated to the latest firmware on the Netgear router. Depending on what you have hanging off of your cable modem, I suppose there's a chance that you're not getting an IPv6 address because of some issue on that device, as opposed to TWC's network itself.

Comcast, the largest isp in the US, already claims to have ipv6 support in all markets since 2014. AT&T the next largest also claims full support. I would guess the majority of US residential internet users have ipv6 support from their ISP but they are just not using it because they have old modems or routers that dont support ipv6

I can confirm that in San Francisco, I've had a DHCPv6-PD assigned allocation for far longer than a year. When Comcast claimed to throw the switch to enable IPv6 for all of their residential customers a while back, something wonky happened to my IPv6 service (and stayed happened for several days) that required me to reboot my cable modem (which then proceeded to download a new config file and reboot several times) in order to resolve it.

I actually think this is less true than it used to be; the problem now is mainly on the server side. A substantial fraction of US residential customers can get IPv6 access as long as their network equipment supports it. But aside from a few prominent names -- like Google, Wikipedia, and Facebook -- the vast majority of the internet is only accessible if you have a v4 address.

From the latest statistics I could find, about 7-8% of Google visitors are connecting via IPv6 [1], but only about 1% of the Alexa top 10,000 sites are v6-enabled. [2]

that 7-8% is also worldwide, in the US it is 21% now

at least here in Canada

TekSavvy covers some of the bigger centers in Canada and has supported IPv6 for some time.
