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…

How Many RIPE Atlas Probes Believe They Have IPv6 (But Are Wrong)?

How Many RIPE Atlas Probes Believe They Have IPv6 (But Are Wrong)?

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.

Using RIPE Atlas User Defined Measurements to Find the Most Popular Instances of a DNS Anycast Name Server

Using RIPE Atlas User Defined Measurements to Find the Most Popular Instances of a DNS Anycast Name Server

Author image

12 min read

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…
