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 …

At the recent RIPE Meeting, the question was raised whether Internet users would see significant filtering of AAAA DNS queries or replies. We used RIPE Atlas measurements to provide an answer to this question.

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…

In response to a huge amount of demand, the RIPE NCC has conducted another survey on the level of IPv6 support for various vendor's Customer Premises Equipment (CPE). The questions in the 2012 focused around the most common access technologies. The results have been published using a simple colour …

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…

The upcoming RIPE meeting in Amsterdam will give plenty of opportunity for "community building" - interaction between the developers of various tools like RIPE Atlas and RIPEstat, and the users of these services. If you want to talk about TTM, DNSMON, K-root, RIPE Atlas Anchors, IPv6 Measurements..…

One way to determine the denseness of the Internet, or its “interconnectedness”, is to look at the path length between Autonomous Systems (ASes). A while ago we looked at that and also at differences between IPv4 and IPv6 networks. Has this changed in the meantime? See our findings below.
