Another Look at RIPE Atlas Probe Lifetimes

We take another, more detailed look at probe lifetimes and the dynamics of probes connecting and disconnecting from the RIPE Atlas infrastructure to try to understand how to keep the network growing in the long term.

IPv4-only RIPE Atlas Anchors Now Supported

Until now, native IPv4 and IPv6 has been one of the conditions of hosting a RIPE Atlas anchor. However, we realise that IPv6 simply isn't available in some would-be anchor hosts' ASNs. As a result, we've decided to support IPv4-only anchors.

Detecting IXPs in Traceroute Paths Using traIXroute

traIXroute is a tool that detects whether and where a traceroute path crosses an Internet Exchange Point (IXP). It uses data from multiple sources and advanced criteria to verify IXP crossings to deal with problems due to replies from third-party interfaces or inaccuracies in the available data about IP addresses assigned to IXPs. These problems can mislead simple heuristics, based solely on the IP address prefixes allocated to IXPs, for the inference of IXP crossings.

Further Analysis of RIPE Atlas Version 3 Probes

We continue to look at failure rates for RIPE Atlas version 3 probes and the possible causes.

EuroSSIG: A Deep Dive into the World of Internet Governance

EuroSSIG 2016, held in Meissen, Germany from 16-23 July, gathered 30 fellows and 30 faculty members together for an intensive week-long introduction to the topic of Internet governance. This was also the year it celebrated its 10th anniversary. The RIPE NCC, which is one of many sponsors, sent two staff as fellows and one faculty member. Below are some impressions.

EuroSSIG Internet Governance Summer School: A Faculty Member's Impressions

I've been a faculty member at EuroSSIG, the European Summer School on Internet Governance, since 2013. Below are my impressions on my experiences during that time, along with what makes EuroSSIG so unique.

Internet Access Disruption In Turkey - July 2016

With the attempted coup in Turkey, reports went out about social media being throttled and/or blocked. We analysed data about this that we collected with RIPE Atlas and the Open Observatory of Network Interference (OONI).

DNS Privacy

The DNS is normally a relatively open protocol that smears its data (which is your data and mine too!) far and wide. Little wonder that the DNS is used in many ways, not just as a mundane name resolution protocol, but as a data channel for surveillance and as a common means of implementing various forms of content access control. But all this is poised to change. Now that the Snowden files have sensitized us to the level of such activities, we have become acutely aware that many of our tools are just way too trusting, way too chatty, and way too easily subverted. First and foremost in this collection of vulnerable tools is the Domain Name System.

Operator Level DNS Hijacking

Following my recent research on DNS hijacking and the cases I have personally observed, I wondered whether this is a common practice among the operators. With the help of RIPE Atlas, I started to think of a solution to figure out whether such practice is widespread in other areas of the world.

Can You Make IPv6 Work Commercially?

Large scale IPv6 deployments suggest that IPv6 is at least a technical success - the technology works. Now it's time to visit the other important question: does it work commercially? Does IPv6 really come with a positive business case? We are about to find out, if you help us... (for instance by filling in the poll next to the article)

Is Your ISP Hijacking Your DNS Traffic?

You might not have noticed, but there are chances that your ISP is playing nasty tricks with your DNS traffic.

Troubleshooting RIPE Atlas Probes: USB Sticks

Some of the third version of RIPE Atlas probes have recently had an issue with their USB sticks. We're investigating what may be causing this issue and have a possible solution, outlined below. (At the same time, we're also looking into a new hardware solution for the future.) If you've had trouble with your probe, please follow these simple steps. RIPE Atlas users everywhere will thank you for getting your probe back online - and we will, too!

Scaling the Internet of Things? Not a Problem!

What makes the Internet of Things (IoT) different from the Internet as we know it? Today's Internet connects people, while the Internet of Things connects... things. What are these things? In the case of IoT, it means embedded computer chips that are attached to some physical device with networking capability.

Open Season

In June 2016, the Organization for Economic Cooperation and Development (OECD) hosted a meeting of ministers to consider the state of the Digital Economy. The central message from this meeting was the message that: “Governments must act faster to help people and firms to make greater use of the Internet and remove regulatory barriers to digital innovation or else risk missing out on the potentially huge economic and social benefits of the digital economy.” All well and good, and as a piece of rhetoric, it seems to strike an appropriately positive note without straying far from what appears to be bland truisms of our time.

Securing Network Infrastructure for DNS Servers

In this article, I'm showing how we can mitigate DNS attacks by implementing a stateless firewall filter at the aggregation or edge router.

K-root Reachability in the Middle East and Central Asia

There are about 600 DNS root server instances deployed around the world. But does everyone have an equal level of access to a root server in their region? Are they fairly distributed? Do all major (and country level) network operators recognise the value in deploying (or peering with) a root server in their network?

LPWA: Things in Search of a Network

Last week I had the opportunity to visit the LPWA IoT Networks Event in Amsterdam, a two-day conference dedicated to the use of low power wide area (LPWA) wireless networks that lie behind many Internet of Things (IoT) solutions that are entering the market.

Reducing the BGP Table Size - A Fairy Tale

The issue of the relative sizes of the IPv4 and IPv6 Internet in BGP came up during discussion at the APNIC/APRICOT meeting held in Auckland, New Zealand earlier this year.
