Measuring Countries and IXPs with RIPE Atlas

We've been working with various Internet Exchange Points (IXPs) over the last few months to see how RIPE Atlas active measurements can provide insight into how they are keeping local traffic local. This could help to improve performance and efficiency for IXPs and their members. To explore this we've created a set of python scripts to analyse Internet traffic paths between RIPE Atlas probes in a given country, and see if we can identify if they traverse IXPs.

Inferring Distributed Reflection Denial of Service Attacks from Darknet Space

This work proposes a novel approach to infer and characterise Internet-scale DNS Distributed Reflection Denial of Service (DRDoS) attacks by leveraging the darknet space. The aim of this work is to extract useful information related to DRDoS activities such as intensity, rate and geo-location in addition to various network-layer and flow-based insights.

Redesigning the RIPE NCC Website: Information Architecture

This article is the next in a series that explains the main changes we're making to the RIPE NCC website as part of the website redesign project. Here, we describe the research we conducted in order to improve the information architecture of the website and the steps we took to implement the changes in our new design.

Visualising RIPE Atlas Anchor Measurements

We visualised the measurements collected by our RIPE Atlas anchor. This allows us to analyse the quality of our connectivity and topology changes and to help debugging network issues. This monitoring page is publicly available.

New Architecture Model for K-root Local Instances

We have redesigned the K-root architecture for our hosted nodes, formerly known as K-root local instances. System architecture and network setup have been simplified a lot. This will reduce our management effort for K-root and reduce costs for K-root hosts.

Quality of ROAs in RPKI Repositories

RPKI.me is a website collecting statistics and information about objects in the RPKI repositories. The web page shows some of the most problematic ROAs present and suggests possible fixes.

Introducing ENISA: Securing European Networks

ENISA, the European Union Agency for Network & Information Security, is an independent body of expertise, set up by the European Union, to secure Europe’s information society. It was founded in 2004 to facilitate the exchange of information between EU institutions, the public and the private sector. The goal is to work together with operational communities to identify pragmatic solutions to current security issues. In this first article, we have asked ENISA to introduce themselves and highlight some of their activities that could be of interest to the RIPE community.

Today's Mobile Internet

It has been observed that the most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it, and are notable only by their absence.

Tracebox, a Tool to Detect Middleboxes

The increasing number of middleboxes (such as firewalls, NATs, proxies, or Deep Packet Inspection) has raised concerns over the impact of such middleboxes on the network and the possibility to innovate. As a result, operators and researchers are studying the distribution and behaviour of middleboxes in large networks. In this article, we will describe a tool called Tracebox that helps in detecting middleboxes. Tracebox was developed at the Université Catholique de Louvain (UCL) and at university of Liège (ULg) in 2013 and funded by Change (INFSO-ICT-257422), mPlane (ICT-318627), and Bestcom IAP. We believe that adding tracebox-like capabilities to RIPE Atlas could give network operators a deeper insight into their systems and help debugging network problems.

Stopping Support for Internet Explorer 8 on Windows XP in RIPE Atlas and RIPEstat

Microsoft ended support for Windows XP as of April 2014. We're about to change RIPE Atlas and RIPEstat to stop support for Internet Explorer 8 running on these systems.

RIPE NCC Membership - Developments After Reaching the Last /8

On 14 September 2012, the RIPE NCC started allocating IPv4 addresses based on the last /8 policy. With more than two years passed, we look at the effects this had on membership numbers and demographics. We also look at what the last /8 policy meant for IPv6 uptake.

NTP Measurements with RIPE Atlas

This article describes how RIPE Atlas probes and anchors maintain their clocks, and how accurate these clocks are. We also plan to make the NTP measurements we describe here available as an additional measurement type for RIPE Atlas users.

Redesigning the RIPE NCC Website: Search Improvements

This article is one in a series that explains the main changes we're making to the RIPE NCC website as part of the website redesign project. Here, we take a look at the ways in which we've already improved the search functionality on www.ripe.net, as well as additional improvements that will come into effect when the redesigned site launches in a few weeks' time.

Internet Interconnection: Networking in Uncertain Terrain

The Internet today consists of more than 49,000 networks. Network interconnection is the Internet’s central feature. Yet, there is little qualitative research on the junctions between networks – about why networks interconnect where they do, or about how network engineers create, maintain or shut down relationships with other networks. Given our current dependence on the Internet, this lack of exploration comes as a surprise.

Deprecating the "changed:" Attribute in the RIPE Database

The RIPE Database Working Group requested the RIPE NCC to replace the “changed:” attribute in the RIPE Database with “created:” and “last-modified:”. Following discussions at RIPE 69, the RIPE NCC has met with the working group chairs and finalised an implementation plan consisting of three phases: 1) introduce the new attributes “created:” and “last-modified:”, 2) make the "changed:" attribute optional, 3) deprecate the "changed:" attribute. Please find the details in this article.

#facebookdown? What Internet Measurement Data Shows

While at this point it is still unclear what exactly happened at Facebook this morning (27 January), we collect data on the Internet control plane (BGP) and data plane that allows us to provide some insight into what happened with Facebook's connectivity to the rest of the Internet.
