List ISPs separately

[JayFoxRox]

The list contains at least one ISP (Netcologne).

It would be interesting to know not only how websites / content-providers adopt IPv6, but also how it's being adopted by ISPs (IPv4 only / DSl-Lite / DS / IPv6 only).

What ways of measuring that do we have?
I am thinking RIPE atlas could help in some way. But it will be hard to distinguish DS-Lite (with v6 disabled) from an IPv4 only provider etc..

Maybe another project for this exists already, and you could include that data, but provide the clean interface of ipv6.watch which still allows users to complain via twitter.

Maybe it could be automated by checking how users connect to ipv6.watch and running some tests with websockets or something. You could keep track of the last X visits for a certain ISP and then make a guess as to which technologies they currently provide.

The issue is probably that this needs state, and it would be working with user data (which isn't too nice for privacy / data protection reasons).

Worst case: it could be a custom file on this repository (or submodule / separate repo), asking users to provide information; basically crowd-sourced.
