I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.

Measuring World IPv6 Day - Some Glitches And Lessons Learned
• 7 min read
As already stated by us and others, World IPv6 Day on 8 June, was a big success. No major issues came to light, and most minor issues that surfaced were resolved, and as such were a useful learning experience. In this article we provide details on some of the events we observed by looking at our me…
When Does World IPv6 Day Start?
• 4 min read
World IPv6 Day is on 8 June 2011. On this day, a lot of organisations, including some of the most popular ones like Google, Yahoo and Facebook, are going to provide IPv6 addresses for AAAA queries for their websites. This will make content available over IPv6 for one full day. Since DNS responses a…
World IPv6 Day - IPv6 Eye Chart
• 3 min read
The RIPE NCC is doing some measurements for World IPv6 Day. One of them is the IPv6 eye chart, a web page that allows you to test your connectivity to selected dual-stacked web sites and World IPv6 participants. The goal is to see if an end user has connectivity problems to dual-stacked websites. T…

As announced earlier, the RIPE NCC is going to measure World IPv6 Day. This article details the measurements we intend to do.
Unsolicited Internet Traffic from Libya

Amidst the recent political unrest in the Middle East, researchers have observed significant changes in Internet traffic and connectivity. In this article we tap into a previously unused source of data: unsolicited Internet traffic arriving from Libya. The traffic data we captured shows distinct c…
6to4 - Why is it so Bad?
• 8 min read
In a previous article we measured that a large percentage of 6to4 connections fail. In this article we show our attempts to find out why these connections fail.
RIPE Atlas - the iPad Drawing

This article is about the lottery of an iPad for people hosting RIPE Atlas probes. As an extra motivator for people to keep their probes up as much as possible, the lottery drawing is weighted based on probe-uptime.
6to4 - How Bad is it Really?
• 6 min read
At the recent RIPE 61 meeting in Rome and at earlier meetings, we heard that connectivity over 6to4 is not very dependable, which hampers IPv6 deployment. I wondered how bad it really is and started measuring it. This article describes what I measured and shows the results. Spoiler: It's pretty bad.
IPv6 RIPEness - The List of 4-star LIRs
• 2 min read
Following up from the IPv6 RIPEness graphs we published earlier, those Local Internet Registries (LIRs) that fulfill all 4 IPv6 RIPEness criteria are now listed on the RIPE NCC web site.
“Thank you for this, Emil and Alun! From looking at the map you provided, it would be great to see an additional anchor in Katthammarsvik. Do you think it's worth trying to add one there?”
Thanks for the suggestion. I think that depends on the physical (cables) and logical (routing) topology near Katthammarsvik in relation to the cable landing there. In a quick search I didn't find datacentres there, which makes me think it would not be too useful. Experts on the local Internet infrastructure would probably be able to answer if it would make sense or not.
This RIPE Labs article has good information on how to avoid effects from unknown attributes showing up at your BGP routers: https://labs.ripe.net/author/berislav_todorovic/bgp-path-attribute-filtering-a-powerful-tool-to-mitigate-alien-attributes/
“Hi Emile, I remember attribute 28 showing up in several previous studies. Interesting to see it causing a problem this time! As bgpdump maintainer, I'd ask you to check out v1.6.2 or higher, since 2020 there is a '-u' flag to output unknown attributes in the short (-m) mode (helpfully submitted by Italo Cunha) - it may make your future parsing life much easier :) Kind regards, Colin”
Thanks Colin, I didn't know, and this would have speeded up my analysis if I had!

We got a request for the HHI scores for other countries. I've put these in a small repo on github together with the code that generated this. repo: https://github.com/emileaben/hhi-eyeballs HHI scores for 2022-03-07 are available here: https://raw.githubusercontent.com/emileaben/hhi-eyeballs/main/eyeball-hhi.2022-03-07.csv
“This is awesome work, thank you! Do you maybe have the script/notebooks/sources to reproduce this? This could be potential used for other countries.”
Hi Jenneth, The observable notebook we used for this is here: https://observablehq.com/@aguformoso/internet-outages-as-seen-by-ripe-atlas . It's a little rough around the edges, so it would be great if you could help improve it!
Thanks for your comment Maxime. I would love to see more analysis too, and the tool allows people to do this. Take for instance this thread on Twitter where Jason Livingood analyses the signals for the US: https://twitter.com/jlivingood/status/1245142990336688130 If others have analysis for specific countries they want to share it would be great to have them collected, for instance as comments to this RIPE Labs post!
