Following up from earlier experiments in which MERIT looked at pollution of IPv4 prefixes, Manish Karir and his colleagues now did an experiment with various IPv6 prefixes. The results can be found in this article.

The advent of IPv6 changes not only the network components, but also the security field shifts. We see new types of attacks or at least variations of the attacks we know from IPv4. This article provides an overview of the IPv6 security vulnerabilities that arise with the launch of IPv6.

The IETF has developed solutions that promote a healthy IPv4 and IPv6 co-existence. The happy eyeballs algorithm for instance, provides recommendations to application developers to help prevent bad user experience in situations where IPv6 connectivity is broken. We study the effectiveness of the ha…

To check the connectivity of an IPv6 device with RIPE Atlas, one typically asks N probes to ping the target and deduces the reachability of the target from the percentage of failures. But RIPE Atlas probes, like many IPv6 devices, often believe they are IPv6-connected while they are not.

In this article we present the first publicly available beta version of the fifth IPv6 RIPEness star. This measures real IPv6 deployment from LIRs in the RIPE NCC service region. The methodology is what we think to be the best compromise yet between simple and fair. In this first version, 573 LIRs …

A DNS anycast name server has several physical instances, all behind the same IP address. Which one is used by a RIPE Atlas probe depends on the location of the probe in the BGP space. RIPE Atlas can query the physical identity of the probe and therefore help to determine which instances have the l…

We developed a tool that allows you to check if prefixes originated by your AS have limited visibility on the global routing table. In the article below we describe some of the results we found after analysing many months of global routing table data.
