The Christmas Goat and IPv6 (Year 5)

Torbjörn Eklöv

This year I didn't even get a good picture of our famous Christmas goat here in the city of Gavle Sweden. The Christmas goat this year survived Christmas but were suddenly on the 28th of December dismounted. The reason for the poor goat's early leave from its own little park downtown Gavle is that it is now the year of the goat in China, and the city of Gavle has a sister-town in China — Zhuhai. 
In Zhuhai, since it is the year of the goat, they thought it would be a fantastic idea to "borrow" Gavles Christmas goat and have it on display in their city during February, with flowers and all.

The beheaded Christmas goat during dismountingTherefore the goat is now on its way to China. That this was going to happen was however very poorly informed to the public, so the response to this move hasn't been all positive. Perhaps the goat never were expected to survive over Christmas but burnt down also this year as the "tradition" dictates…

Anyhow, I still got 31 days of measurements with 22 GBs of logs and 92 million rows, and it was really good logs! This year the unique IPv6/IPv4 addresses was 11.1% IPv6!!!

I will repeat this number — 11.1% IPv6. This value is tripled from last year and it looks like we have a triple increase every year now. Will it be 33% next year one might wonder? I haven't measured Teredo and 6to4 this year and I have only focus on an AAAA/A RR for the goat picture.

Values from previous measurements:

  • 2010 – 0.1% native IPv6
  • 2011 – 1 %
  • 2012 – 1.4 %
  • 2013 – 3.4 %
  • 2014 – 11.1 % (!!!)

Google's IPv6 adaption page for Sweden says 1.25% at the moment. I have no reason to see this as nothing but accurate, the most IPv6 I have measured on the goat is from outside Sweden.

From Google's IPv6 adaption page for SwedenA major ISP in Sweden — Tele2, enabled IPv6 in their 4G network this year and 1% of the IPv6 traffic to the goat was from Tele2. From the largest ISP in Sweden, TeliaSonera it was 0.02%.

With this 11.1% in mind, I hope that everyone who enables IPv6 on some public resource will understand — you can't just add an AAAA RR and forget to monitor it.

My company, Interlan, has many, many customers with IPv6 enabled inside, and we monitor the functionality. At least once a week, I think, we must send an e-mail to a customer, not seldom a Swedish authority or municipality, who have a broken IPv6 on their www.

Take a look at myndighetermedipv6.se (Swedish authorities with IPv6) and look at every date in January 2015 for example. The first section is the one where the www. DNS and MX is working ok. As you will see, the status changes every day and it is not stabile.

Hopefully we will see a measurement that reaches over 30% on the Christmas goat-IPv6 next year! :)

Have a happy and good IPv6 year during 2015!
