For many years I have been the leader of the Research and Development team at the RIPE NCC leading a dedicated team of thinkers to support the RIPE community by providing network research, data analysis and prototype tool development and services including RIPE Atlas and RIPEstat. As of 2023, I'm working as a principal engineer in order to assist the CTO and the RIPE NCC's information services.

How We Distribute RIPE Atlas Probes
• 7 min read
With a limited supply of hardware probes and thousands of networks yet to be covered, how do we prioritise the applications to host probes? In this article, we explain our hardware probe distribution strategy to improve RIPE Atlas’s global coverage.
Robert Kisteleki: RIPE Atlas - A Distributed View of the Internet
• 2 min read
Twelve years ago the RIPE NCC set out to build the largest Internet measurement network ever made. Today, RIPE Atlas provides users with an unprecedented understanding of the state of the Internet in real time. In this episode, I catch up with Robert Kisteleki to talk about how RIPE Atlas developed…
Help Build a Bigger, Better RIPE Atlas
• 6 min read
When it comes to RIPE Atlas, bigger is better. Each new probe adds another vantage point, bringing the measurement platform closer to its goal of providing an unprecedented view of the state of the Internet. But expansion into new geographical locations and networks wouldn't be possible without the…
Language Support for RIPE Atlas Software Probes
• 5 min read
Software probes provide yet another way to help grow the RIPE Atlas network. As many new hosts opt for this alternative, getting RIPE Atlas into new places means helping people install and run the relevant software packages. Language support will be key to this, and we have a plan to provide it, bu…
Impressions from the Internet Measurement Conference 2017
• 6 min read
This year's Internet Measurement Conference (IMC) was held in London from 1 - 3 November. In this article we highlight some of the presented work that we think is interesting and that the RIPE community might find useful.
RIPE NCC Technical Services 2017 - Part Three: Focus on Tools and Research

Please find below the third part of our technical services update. This time we're focusing on our research activities and a number of tools we are developing.
RIPE NCC Technical Services 2017 - Part One: Focus on RIPE Atlas
• 11 min read
In 2013 and 2015 we provided high-level reports on the status of our plans for our technical services and tools. It is time for an update. In this first article we will focus on RIPE Atlas.
RIPE Atlas WiFi Measurements
• 7 min read
We're thinking about implementing WiFi measurements in RIPE Atlas, and we want to know what you think. There are several different ways we could do this - find out more below and then take our poll to make your voice heard!
Iran and K-root: The Rest of the Story
• 11 min read
Dyn Research published an article on K-root recently. Here we would like to augment the picture with data from RIPE Atlas in order to provide a more complete picture of the effect of the K-root node in Iran.
Comparing TCP and UDP Response Times of DNS Root Servers
• 8 min read
We did some measurements on the round-trip (RT) values of DNS queries for SOA (Start of Authority) records from our RIPE Atlas probes, over both UDP and TCP. We plotted the TCP/UDP ratios on graphs, and found that, as expected, for the majority of the measurements, it is around 2. However, we also …
“Hi, I am the project manager of the zonemaster (zonemaster.net) dns validation tool (https://github.com/zonemaster/zonemaster/blob/master/README.md). This open source tool is developed by Afnic (the French registry) and IIS (the Swedish registry). This tool is used by RIPE to validate the reverse IP address in the RIPE database. IMHO, it is the best available tool for DNS zone validation (everything open (BSD-2 licence for source code and Creative Commons Attribution 4.0 International License for the documentation) and with extensive documentation of all its modules and test cases) and it used by many well known DNS registries and registrars. My question is - will it be possible to integrate Zonemaster source code to verify a domain 's zone from different vantage points from RIPE root anchors? If you have any feedback to provide, please contact me at sandoche.balakrichenan@afnic.fr”
It's not entirely clear if you want to add RIPE Atlas support to zonemaster (then you can simply call APIs and integrate results that come back) or the other way around (adding zonemaster code to anchors -- which is much harder to do due to differences in working models).
“That is a rather powerful VM (the TL-MR3020 probes has 32MB ram and a Atheros AR9331@400MHz). Do the VM need to be so powerful? I would love to participate with a probe, if I could run a probe on my (weak) Intel Atom server, either as a VM or in some sort of container (systemd-nspawn/docker?). I will be more than happy to experiment if I could get access to the anchor.ks file (fell free to mail me at firstname@lastname.dk).”
There's need for more resources for an anchor than for a probe. It has services on it, for example. About probe VMs: we're looking into the possibility to introduce "software probes" deployable as a software package or such. We'll report back on this activity when we have more information.
“Given the proliferation of cheap single board computers such as the Raspberry Pi and/or most organisations having a virtualization platform of some sort, wouldn't the development of one or more images for these platforms be a better solution than tying the organisation to a single hardware vendor?”
Besides working with the above mentioned hardware, we're talking to other vendors to see what they can offer. One constraint is that we want to avoid using fully repurposeable hardware (like the Raspberry Pi) -- we fear that too many would be taken as "free hardware". We're also looking into virtual solutions: a VM anchor pilot is already ongoing. We will likely work more in this space.
“Hello, Is it possible to use INRDB and how? I need to search if an Internet prefix was announced on the Internet between 2012 and 2013, by which AS, for how long etc. Can you please help me?”
Hi, you should check out RIPEstat, specifically the routing history widget: https://stat.ripe.net/widget/routing-history#w.resource=193.0.0.0%2F21
“I also wonder whether the type of person hosting a probe has changed over time. At first it may have been more engaged "enthusiasts" who were personally keen to have a probe and ensure it remain connected. Later participants may have agreed to host a probe based on encouragement from an ambassador, but they don't really care as much or notice when their probe has disconnected.”
Indeed, this is a likely cause. However, it's difficult to measure such an effect.
