What is confusing me is the Netherlands. We only have about 13% adoption. I'm on one of the largest ISPs KPN and get 10/10 on IPv6 tests. Is this because I use a custom router? I'd expect it to be a lot higher since apparently KPN supports IPv6.
* VodafoneZiggo has 40-45% of the home market, but also 25-30% of the business market and 20-25% of the mobile market [1]. They seem to offer IPv6 on their home and business connections, but not on their mobile connections [2, 3, 4].
* KPN (35-40% home/biz, 25-30% mobile): IPv6 for homes (except older modem types) and mobiles, but not by default for businesses [5, 6].
* Odido [ex T-Mobile] (30-35% mobile, 5-10% home/biz): no IPv6 across the board [7, 8].
* Eurofiber (20-25% biz): has IPv6 [9].
* Delta (5-10% home): no IPv6 [10].
* Unspecified smaller ISPs (0-5% home/biz, 10-15% mobile): unknown.
* Finally, a number of wholesale access providers, where the customer presumably has a say in IPv6 support.
This works out to 75-90% IPv6 in homes, 45-60% in businesses (ignoring wholesale) and only 35-45% for mobiles.
So, the mystery is not solved, because this data still doesn’t support Google’s 13% figure…

The Ziggo shift would have made a huge impact on the national total.
