<p dir="ltr">(Apologies for the top-post - I am mobile).</p>
<p dir="ltr">I wondered something similar yesterday. I am an Internode customer at home, ans have a Fritzbox as my CPE, Win7 as my desktop OS, and Android 4.1 on my phone.</p>
<p dir="ltr">I know my Win7 box has full IPv6 connectivity (having run dozens of tests), but to my knowledge my Android phone doesn't yet support IPv6 ( <a href="https://code.google.com/p/android/issues/detail?id=3389">https://code.google.com/p/android/issues/detail?id=3389</a> - partial support available in 4.2 apparently).</p>
<p dir="ltr">What I don't know or have any visibility of is how much of my Internet traffic is IPv6 vs IPv4. For that matter, really of what apps do and do not support IPv6 transit and which do not, and even if an app (a mail client for example) supports IPv6, whether the server (Internode's mail server for example) supports IPv6. And finally, if everything supports IPv6, what priority is given to IPv6 over IPv4 (or vice versa).</p>
<p dir="ltr">I am sure all the answers to all of these questions are out there somewhere, but as someone who has about a billion other things on my plate right now, spending the time to find out and/or make any changes required to improve my IPv6 utilisation is right up there in my priority list along with things like booking my first moon flight and discovering the cure for broken fingernails, given things "just work" right now for me regardless of the version of IP being used for transit.</p>
<p dir="ltr">This leads me to believe we have two other problems to solve, and that we''re also using a potentially bad metric for judging success. The two problems are visibility and priority. The metric (what percent of global traffic is IPv6 is bad because although I am ready, right now on my home network for IPv4 exhaustion and an IPv6-only world, I doubt I am mail g use of that readiness - and I've highlighted another piece of the puzzle that needs tracking - application readiness.</p>
<p dir="ltr">So, does there exist:</p>
<p dir="ltr">a) A register of IPv6 capable/enabled/exclusive applications/operating systems/hardwRe? If not, I am happy to start one.<br>
b) A way for me to tell, on the fly, just how much of my personal IP traffic is actually IPv6?</p>
<p dir="ltr">Regards,</p>

I've got an IPv6 address on my server but it doesn't look like my mail application is using it if you look at the headers in this message.<br>
<br>
I discovered this because I thought it might be interesting to have a bit of a look at my favourite lists and see how we're going in industry for dual stacking.<br>

Mark's comments were fear enough this morning.<br>
<br>
If he's bothered to take just 10 seconds to have a look at my message headers, it's no wonder he'd be thinking I'm just yanking the chain.<br>
<br>
I dual stacked that VPS 18 months ago, but it seems it's not playing the game.<br>
<br>
It's no wonder that we're only seeing 1% traffic if the traffic isn't flowing.<br>
