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.

The RIPE NCC will shortly reach a point where we have approximately one month's worth of IPv4 address space (approximately /10) to distribute before we reach the last /8. Once we reach this point, several adjustments will be made to our standard procedures, so the RIPE NCC decided to do a "dry run"…
