[apologies for duplicates]

Dear colleagues,

We prototyped a method to measure the IPv6 capabilities of caching DNS 
resolvers that end-users use when browsing the web. The results of these 
measurements are now published on RIPE Labs:

1. A summary of the measurements and results can be found here:

2. Some more detailed analysis (including a breakdown of IPv6 usage per 
country and city) are here:

3. The methodology we use for these measurements are described here:

All articles can be accessed from the RIPE Labs home page at

If you have any comments or suggestions, please do not hesitate to 
submit them to the RIPE Labs forum or send them directly to me.

Kind Regards,
Mirjam Kuehne
