Google Analytics for WordPress – IPv6 version

Ahead of the World IPv6 dayAPNIC has launched an useful initiative to collect statistics regarding IPv6 connectivity. If you are interested in testing your clients’ IPv6 capabilities, you can use the APNIC Labs Google Analytics Tracking Code. This allows you to test your customers’ experiences connecting to your website via IPv4, IPv6, and dual-stack. Read more »

IPv6 considered a problem by some users

I have a Google Blog Search Alert looking for posts over IPv6 in my RSS reader. What strikes me is the number of posts explaining how to disable IPv6 in Windows Vista, MacOSX, Ubuntu and other flavours of Linux.

It looks like disabling IPv6 makes web browsing faster for a lot of people, independently of which operating system is being used. One guy even wrote in one of his postsIn order to fix this problem” . IPv6 was supposed to be a solution, not a problem.

I can think of several rational explanations for the poor user experience. If the DNS query for a web site first returns a AAAA record and you do not have IPv6 running smoothly, the browser will first time out before trying the IPv4 address. If the IPv6 tunnel broker, gateway, etc is overloaded, you are up for a painful experience, too.

However, it is worrying that people need to disable IPv6 on their computers. If and when there will be IPv6-only web sites, they will not be able to access them.

Letter to my ISP

I sent the following to my ISP today:

You may be aware that the available pool of IPv4 addresses will be exhausted in 3 years from now. Here are some links to more information. (and similar announcements form other RIRs)

By way of this e-mail, I wish to formally ask you to make IPv6 support available to your customers.

We are often told that ISPs do not deploy IPv6 on  their network because there is no user demand, so I thought it may be useful to formally ask for it and inform you that I am willing to pay a small extra for a decent IPv6 service.

My own blog post on the subject is here:

I do not expect any answer, but if it happened, I would post it here.

Update 2 june 10:21am:  The ISP has closed the ticket, without even bothering to reply. Obviously “raising awareness” is  not enough. One of these days, I will have to vote with my feet. The problem of course is that most other Belgian ISPs are even worse …

European Commission pushes IPv6 forward

The European Commission has released a communication on IPv6, in time for the IPv6 Day in Brussels next 30th May.  It goes in the same direction as the report presented at the OECD Ministerial meeting on “Future of the Internet Economy”, that was held in Seoul, Korea earlier this next month. At the same time, the Commission committed to make its own web services available on IPv6 by 2010.

It is good to see that intergovermental organizations take the lead on this, after 10 years of failure of the private sector to actually deploy IPv6. This is a good example of why governments are needed in the Internet governance arena, be it the IGF or the GAC in ICANN.

Quick and dirty fixes like NATs allow for small investments and high short-term returns. This is what most CEOs in the Internet industry are concerned with,  because they risk to get fired if they do not provide a good and quick return to shareholders. When a long term and societal vision is needed, governments become key leading partners.

It is true that these governments also include a bunch of “supreme guides of the people’s revolution” and other sorts of autocrats and dictators. Indeed, they censor and control their local Internet. These are the same people who control other media like TV or the written press. There is nothing new under the sun, and I still do not understand some in the Internet community who like us to think the Net is different from other media and that the (bad) rules do not apply.

This is why we need the increased presence of democratic governments in Internet governance circles. Unfortunately, the current ideology in democratic countries is to let the private sector do whatever it  wants, with little political support. Not-so-democratic governments, on the contrary, tend to be very active. The end result, as we see in the IGF, is that the latter come up with requests that neither the private sector nor the “civil society” (whatever that means) can counter, because they lack the political weight. A good dictator knows the best way to silence the private sector is to become one of its customers, because no company wants to loose business.  Which leads us back to paragraph 3 above.
