at RIPE 65, Lorenzo Colitti from Google raised the question whether Internet users would see significant filtering of AAAA DNS queries or replies, either by their ISP or by their Customer Premise Equipment (CPE). Emile & Philip used RIPE Atlas to provide an answer to this question.

Thanks for publishing the results!

When you did the AAAA measurements, did you distinguish between the probe not getting a response (e.g., if the dig command timed out) and the probe getting a NODATA response?

[I tried to look at the raw data to answer this question, but wasn't able to find out how to download it. I can see the probes that performed the measurement, but not that the results were. Am I doing something wrong?]
