FYI. Some non-IPv6-related bits have been snipped.

Hi,

I checked the current IPv6 usage of our homepage www.freebsd.org

In the last 30 days we had 5.32 million page views. Many are from web
crawlers (bots) and other automated scripts (nagios, curl, libfetch).
Apparently, 2.73 millions page views (51.5%) are from humans (or your
cat 

1.35% of the page view are IPv6. For the bots it is much higher: 4.8%

You can find Tore's measurements at http://www.fud.no/ipv6/, updated every day.

Hi,

as Steinar has already pointed out, you can see the daily stats on my
web site at <http://fud.no/ipv6>.  There hasn't been too many things
going on since spring, but I can try to sum up some key points:

- Brokenness percentage is currently at slightly above 0.05%.  This is
unfortunately considered by my customers participating in the experiment
as too high to deploy dual-stack, especially as there currently are no
Norwegian ISPs that provides IPv6 to end users.

- As I noted in the last post to the list, Opera fixed their web browser
in March.  This had a very positive impact on the brokenness, which is
very clearly visible in the graphs.  At the moment there's so few users
of older broken Opera versions that the brokenness they cause is barely
distinguishable from statistical noise.

- Mac OS X is currently the biggest contributor to the brokenness, by
far.  The brokenness percentage drops by 70-80% when disregarding all
hits from Mac OS X.  As I've noted earlier, a fix for this is likely to
be included in OS X 10.6.5 which is currently available in beta
versions.  I doubt, however, that (close to) all OS X related brokenness
will vanish overnight - there are still many users of OS X 10.4 and 10.5
out there who won't be able to install the update.
Nevertheless I'm certain that the release of 10.6.5 will have a positive
impact, and it will be exciting to see exactly how large.

- The brokenness decreased significantly during the summer months.
One explanation for this is that the publicly run student dormitories
tends to empty out then, and they are the single largest network
contributor to the brokenness issue (currently accounting for about 35%)
as they discard all 6to4 traffic in their firewalls, thus exacerbating
the OS X/Opera problems significantly.  Several other enterprises and
governmental networks do the same thing, but the student village network
is much larger (in terms of end-user count) than any other 6to4-hostile
network in Norway at the moment.

That's all I could think of right now...

Best regards,

RE: IPv6 brokenness in Norway

Tore

Thanks for the additional explanations and for running this statistics and explaining how you do it.

Just tossing an idea in the air: several content providers are indeed reluctant to go direct with a AAAA for
their site for the reasons below. 

Therefore, it would be useful if there was a web site such yours where any webmaster could go, register its
customer name, copy & paste some code in their HTML pages and get detailed statistics about brokenness of
its own audience after a couple of days.

In the same way as done by Andrew at http://testv6.stdio.be but with you measurement

I'm sure many people would find that useful, however I don't have enough
time or resources to undertake such a project myself, I'm afraid.

Re: IPv6 brokenness in Norway

Just wondering, are your DNS servers set to respond to AAAA requests when it is sourced from an IPv4 address?

They do.  There's no masking of AAAA responses to any queriers.

Opera have just released a 10.63 RC with more IPv6 fixes for
Linux/Mac, see
http://my.opera.com/desktopteam/blog/2010/10/05/opera-10-63-release-candidate
(the fix in March was only for the Windows version).
