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.

Interesting Graph - IPv6 Allocation Requests
• 1 min read
This graph shows the number of IPv6 allocations received since 2007 when the RIPE NCC started to allocate IPv6 address space.
Filtering After Recent Chinese "BGP Hijack" Does not Affect RIPE Region
• 1 min read
Related to a thread on the NANOG mailing list about "BGP hijack from 23724 -> 4134 China?", we checked if any of those prefixes originated in the RIPE NCC service region.
IPv4 Address Allocation Rates
• 5 min read
On 30 January 2010 the RIR system reached a small milestone: on this day APNIC has surpassed the RIPE NCC in terms of total allocated/assigned IPv4 address space, as seen in the RIR stats files. On this occasion we decided to look a bit into how IPv4 allocation/assignment rates changed over the las…
REX Usage Report
• 3 min read
After the Resource Explainer REX has been available for four weeks, we looked at the usage statistics collected by the tool to get a better ide how useful this tool could be for the wider community.
A Guide to Making Movies

While walking around the hallways at RIPE59, a couple of people asked me how the movies were made, what tools did I use and such. So here's a short summary on what I did to produce these movies.
REX - the Resource Explainer
• 4 min read
The current version (v0.1) knows only about IPv4 address space. We went for the most difficult part first. ASNs and IPv6 address space will follow (please note the follow-up articles below describing additional functionality about the Resource Explainer).
Intro to INRDB - the Internet Number Resource Database

INRDB is a non-conventional database hosting many different, number resource related data sets.
We're going to the Movies!

Let us show you the RIR assigned and allocated IPv4 space, and some indication on how that's routed in the Internet. Get out the popcorn! Satisfaction guaranteed!
“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.
