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].
Their data must just be out of date. It's been over a year that I've had IPv6 with Ziggo business and home. As you say, Vodafone mobile still only does IPv4 though.
The Ziggo shift would have made a huge impact on the national total.
