This article describes our recent collaborations with France-IX on collecting data plane and control plane Internet data with RIPE Atlas and the RIPE NCC's Routing Information Service (RIS).
LatencyMON is a new RIPE Atlas web application that you can use to easily visualise and compare multiple latency trends collected by groups of RIPE Atlas probes.
Through empirical research, SHARE Foundation created a map of the Internet in Serbia and analysed the implications network structure could have on Internet filtering. By visualising and analysing the structure and topology of individual Internet Service Providers in Serbia, we tried to determine how easy it would be to install filtering devices on these networks. This data was used to inform the government on the proposal of a new law. In addition, the output of this research can be used for different qualitative measurements of the network, such as bandwidth, IPv6 penetration and Internet throttling.
If you monitor your external Internet connectivity, you may wonder which machine is the best to ping. Hesitate no more - you can use RIPE Atlas anchors as landmarks.
In October 2014 we started announcing a few longer-than-/24 prefixes and determined they were not very visible according to the Routing Information Service (RIS) and RIPE Atlas measurements. Now, almost a year later, we revisit this.
This article is a summary of an academic paper, Visualization and Monitoring for the Identification and Analysis of DNS Issues, that was presented at the Tenth International Conference on Internet Monitoring and Protection in Brussels in June 2015.
North Korea is one of the most secluded countries in the world, but it is nonetheless connected to the Internet. We investigate North Korea's Internet connectivity in light of recent outages and discuss the fragile nature of its setup.
We investigated the role IXPs play in the Italian Internet ecosystem. Do peerings at IXPs have a positive effect on key performance indicators such as latency, hop count, packet loss and jitter? Do they reduce the number of out-of-country ISPs traversed by traffic between users located in Italy and critical Internet services like banks and public administrations?
Anycast is used by most of the DNS root-servers and other services like Cloudflare. It provides localisation and scaling benefits to clients using the anycasted service. An anycast service uses one IP for several instances of the same service. The routing system is then responsible for directing a client to the closest instance of the service. In theory, a client should always reach the closest instance, but it turns out that this is not always the case. At the DACS group of the University of Twente, we analysed the anycast infrastructure of K-root and tried to find how many clients reached the closest instance.
In an effort to increase the growth rate of connected RIPE Atlas probes and achieve better coverage across the globe, our Measurements Community Building team is experimenting with new outreach methods.
