The Seismograph is an interactive RIPE Atlas tool that allows users to analyse and visualise ping measurements. Here we explain the tool's different features and how you can make the most of them.

The main view of DNSMON

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.

The user experience of an Internet service depends partly on the availability and speed of the Domain Name System (DNS). DNS operators continually need to identify and solve problems that can be located at the end user, a name server, or somewhere in between. In this paper, we show how DNSMON, a production service for measuring and comparing the availability and responsiveness of key name servers, correlates and visualizes different types of measurements collected by RIPE Atlas vantage points worldwide. DNSMON offers an interactive view, both historic and near real-time, at different levels of detail. It has successfully revealed and allowed analysis of many operational issues, including less obvious ones

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.

Please read about this new milestone release of the popular BGPlay web application. It can now receive BGP messages using WebSocket and update the visualisation on the fly.

We used a number of RIPE NCC tools and data sets to take a quick look at the recent DDoS attack on Dyn’s infrastructure. We wanted to see if this could be found in the data produced by the RIPE Atlas community.

TraceMON is a client-side tool for visualising network topology generated by traceroutes reaching one or more targets in a network. It provides a one-click access to a set of information useful during day to day operations.

Upstream Visibility is the new tool produced by the Computer Network Research Group of Roma Tre in collaboration with the RIPE NCC. It is a web application which proposes a concise way of visualising interdomain routing data of a specified prefix.

The Network Traffic Measurement and Analysis Conference (TMA) took place in June in Vienna, Austria. A full week of events was scheduled - including a PhD school about Big Data on Monday and Tuesday, the TMA Experts Summit on Tuesday, and the main conference from Wednesday to Friday. Here's my summary of the week!

Some time ago we introduced RIPE IPmap. Now it’s time to take a look under the hood and see how the geolocation of Infrastructure IP addresses is done.

This is a brief tutorial that explains how to monitor BGP prefixes easily and effectively. For this purpose, we will use an open-source application named BGPalerter which is ready to go and requires almost no configuration. Currently, we use this solution at NTT, one of the largest global providers, on our tier-1 Global IP Network.
