I've had IPv6 natively for 4+ years in San Francisco[0] on my residential cable connection. This appears to be one of the few things Comcast does right.

Without any extra effort the following sites (small sample from Alexa top 500) use IPv6:

* google.com

* youtube.com

* gmail.com

* facebook.com

* wikipedia.org

* netflix.com

Without IPv6 (no AAAA DNS records):

* reddit.com

* amazon.com

* twitter.com

* news.ycombinator.com

* imgur.com

* bing.com

* ebay.com

It's happening, slowly. ISPs who care are supporting it. A significant portion of my every day web traffic is over IPv6 and nobody has noticed. People on my local network are using it on Linux, Windows and Mac OS X and they don't even know what IPv6 is.

Google is clearly leading the IPv6 charge and has a statistics page[1] for those interested.

Another major source of IPv6 traffic that most people are unaware of it the cell networks. Most cellphone providers use IPv6.

Is that in the US? In my Eastern European country, IPv6 has not become directly available to mobile customers. One of our major ISPs began offering IPv6 addresses for fiber customers over half a decade ago; all the customer needs to do is set up PPPoE on the router and the connection automatically gets both IPv4 and a couple of IPv6 addresses. But if you add mobile internet to your contract with that ISP, that mobile connection still only provides an IPv4 address that I assume is NATed to hell. The same is true of internet connections through a large pan-European mobile provider here.

US, Canada, most of Western Europe, India?

I don't think that Canadian ISPs are in on this. In particular, almost all Canadian mobile customers are on Bell, TELUS, and Rogers. I'm on TELUS right now and I fail test-IPv6.com. Telus and Bell actually share much of their mobile network so I'm not sure Bell would fare better. And I was on Rogers as recently as 6 months ago and they didn't have IPv6 either. And my home ISP, a small fibre ISP, doesn't have IPv6.

Anecdotally, I'm on Telus in Western Canada and I do have ipv6. 10/10 on that test.

LTE or DSL? I'm on LTE in Vancouver and it fails (and has consistently in the last 6 months).

Are you in Calgary? Telus always rolls out experiments in Calgary first. For example, until recently their only deployed GPON networks have been in Calgary subdivisions.

I'm on Fido/Rogers in Quebec/Ontario, and they have had IPv6 enabled for 1-2 years. Make sure that your APN settings enable IPv6 (in Android, there's an option for that).

Mobile is the main reason why Canada is >15% adoption on google-stats [1]. On DSL/cable, Rogers and Cogeco provide IPv6, as do smaller re-sellers such as Teksavvy on DSL, but otherwise big players such as Bell and Videotron have been dragging their feet and giving lame excuses.

I tried a few months ago and can enable IPv6 on my LG V20 (on Telus LTE) and it does indeed pick up an IPv6 address but test-ipv6.com complains of MTU problems.

Sites did load over v6 but it was slow compared to v4.

0/10 on my Vodafone cellphone in Bangalore.

I know very little about this company, but this headline had caught my attention: "Reliance Jio boosts India past 20% IPv6 capability" https://blog.apnic.net/2017/02/07/reliance-jio-boosts-india-...

I have a Jio SIM card, will try test and report back.

9/10 on Jio. Nice!

Same here in Germany (Vodafone network).

The largest two dutch providers (KPN, Vodafone) don't have IPv6 on their mobile networks.

> Another major source of IPv6 traffic that most people are unaware of it the cell networks. Most cellphone providers use IPv6.

Yes. I have T-Mobile in SF, and going to test-ipv6.com shows "10/10 readiness score".

I get 0/10 on mobile in Taiwan.

Idem here 10/10 (Brazil/Vivo-Telefónica). My cable ISP has had IPv6/ CGNAT but they backed away for now, perhaps due to problems in some users

0/10 here, on Cellcard in Cambodia. No IPv6 address detected, but the DNS server appears to have IPv6 internet access.

Same 10/10 score with Google's Project Fi which just resells T-Mobile, Sprint and US Cellular service.

I don't think that's right at all. It might be true in the USA, but that's only like 3 providers, isn't it?

I'm in the UK and I don't have IPv6 on my mobile or at home. I travel to ROI often and my phone has never picked up on IPv6 address. I was in Italy a couple weeks ago and I never got an IPv6 address. I know I checked because a friend of mine keeps telling me bullshit like this about how real IPv6 is, and I've never had an IPv6 address.

I was in Spain at the beginning of the year and didn't get one; and Germany late last year: No IPv6.

But are you roaming in those places? For reasons I don't understand fully but are presumably billing related your IP traffic gets tunnelled back to your home ISP when roaming, or at least, it used to.

Mobile networks use a lot of IPv6 internally, but that is invisible to the customer. Your IPv4 or v6 traffic in tunnelled inside IPv6 between nodes of the cellular network. That may be the cause of some confusion.

If someone thinks I'm driving a car when I ride in a taxi, I would say they're the confused one.

In Germany, only Deutsche Telekom (and resellers such as Congstar) supports IPv6 on mobile (for both prepaid and postpaid). And it works great, even when tethering.

Since you're from the UK, I suppose you are a Vodafone customer and therefore roaming in the Vodafone network in Germany (which does not support IPv6 yet).

On some networks/devices you might have to enable IPv6 explicitly, by setting the APN to IPv4/IPv6.

In Singapore, Singtel seems to be the only provider that supports IPv6. Unfortunately only for postpaid plans.

I was using Three last time I was in Germany. I just switched to Vodafone because they offer 4G tethering when roaming internationally.

In the UK I can confirm vodafone doesn't do IPv6

Google may be leading the IPv6 charge on their own public-facing properties; they have yet to support it in Google Cloud.

Well, partial at least. Appengine since 2010, cloudsql for a couple of years, and load balancers for the last few months.

To differentiate your traffic like that did you use something like wireshark to intercept the router traffic?

That's pretty neat, I'd like to check mine out.

You can see the remote address in Chrome's dev tool's network tab as well. Go to the network tab, pick the request for the page, and click on it, you'll see the remote address. If it's IPV6, you'll see the hex notation, like this: http://i.imgur.com/YK9vD53.jpg

Interesting from the chart that weekends seem to have noticeably higher IP6 than weekdays.

IPv6 is less common at work, more common at home.
