This is a followup article to "Counting DNSSEC" that reflects some further examination of the collected data. This time I'd like to describe some additional thoughts about the experiment, and some revised results in our efforts to count just how much DNSSEC is being used out there.

We did some measurements on the round-trip (RT) values of DNS queries for SOA (Start of Authority) records from our RIPE Atlas probes, over both UDP and TCP. We plotted the TCP/UDP ratios on graphs, and found that, as expected, for the majority of the measurements, it is around 2. However, we also …

IPv6 RIPEness helped in creating awareness and got people into action with regards to their first steps towards deploying IPv6 in the RIPE NCC service region. Up until now IPv6 RIPEness didn't measure actual IPv6 deployment. In this article we propose a measure (a "5th star"), which attempts to mea…

When we experienced an occasional operational issue with the data returned by one of our name servers, we wanted to verify DNS responses from a number of widely distributed measurement points (vantage points). RIPE Atlas was just the right service to provide us with the necessary raw data.

It is possible to measure how well we are doing with DNSSEC? How many of the DNS resolvers will now perform DNSSEC validation of a domain name? How many of the Internet's user population are using these DNSSEC-validating resolvers? In this article we will explore a way to answer these questions, an…
