About the author
Based in Amsterdam, NL
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.
IPv6 RIPEness - the Sequel
• 4 min read
As a follow-up to the article IPv6 RIPEness of LIRs, we did more analysis based on LIR signup year, size and the industry sector that the LIR operates in.
Interesting Graph - IPv6 and RIPE 60

We measured the number of web clients connected to www.ripe.net during the RIPE 60 meeting in Prague. The results are shown in this graph.
Interesting Graph - IPv6 RIPEness Movie

After creating a rating system, in which RIPE NCC members can get up to four “stars” for IPv6 services, depending on certain criteria, we now looked at the increase of IPv6 RIPEness over time. See this illustrated in this movie.
Interesting Graphs - Priming Queries to the Root Servers
• 4 min read
There was a slight increase in the number of sources that issue priming queries to DNS root servers seen on 18 March 2010, right after the introduction of a signed .arpa zone. See here an analysis and some graphs.

We have been measuring the number of clients connecting to www.ripe.net over IPv6 and made some interesting observations.
Slight Increase in DNS Resolvers Doing Priming Queries after .arpa Signing - Why?
• 4 min read
The roll-out of a signed root-zone at K-root on 24 March 2010 was uneventful. But we saw the number of resolvers doing priming queries increase slightly since 18 March 2010 and wanted to find out why.
Measuring IPv6 at Web Clients and Caching Resolvers (Part 2: Country Level and other Statistics)
• 13 min read
In Part 1 of this article we showed some statistics on IPv6 at end-users and at caching DNS resolvers. In this part will dig deeper into the data we collected and show details on mobile device use of IPv6, country- and city-level IPv6 deployment numbers, and AS-level statistics.
Measuring IPv6 at Web Clients and Caching Resolvers (Part 3: Methodology)
• 8 min read
In Part 1 and Part 2 of this article we showed various statistics on IPv6 measurements of web clients and caching resolvers. In this part we explain how the measurements were done.
Measuring IPv6 at Web Clients and Caching Resolvers (Part 1)
• 7 min read
It is important to keep an eye on how the IPv6 Internet develops. We wrote a script to measure the IPv4 capability, IPv6 capability and IPv4/IPv6 preference of end-users visiting our site. What is unique about this script is that it allows us also to measure the caching DNS resolver that the end-us…
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 …
Number of New LIRs and their IPv6 RIPEness
• 3 min read
We observed an increase in the number of new LIRs in the RIPE NCC service region. Many of these new LIRs show 1-star IPv6 RIPEness.
Internet Traffic During the 2012 Olympics

Following on from the European Championship earlier this year, we looked at changes in Internet traffic volume at Internet Exchange Points (IXPs) during the Olympics. This is a joint project with Euro-IX.

RIPE NCC Active Measurements of World IPv6 Launch Dataset
• 1 min read
As part of our Data Repository, the RIPE NCC has released a new dataset. This dataset contains DNS lookups (A+AAAA), ping/ping6, traceroute/traceroute6 and HTTP fetches (IPv4/IPv6) from 53 vantage points (TTM, CAIDA Ark and others) to 60 websites involved in World IPv6 Launch. The data covers the p…
Internet Traffic During Euro 2012 - Final Conclusions

This is the last in a series of articles in which we look at traffic statistics at Internet Exchange Points during the European Championship 2012. This time we looked at IXP traffic during the semi-finals and the final. In addition we also look back over the entire 5 weeks of matches and draw some …

First Measurement Results from IPv6 Launch
• 3 min read
Like last year during World IPv6 Day, the RIPE NCC has been doing various measurements during World IPv6 Launch on 6 June. We will publish the results in a series of articles on RIPE Labs.
“Ghost routes: https://www.sixxs.net/tools/grh/what/”
I've added a reference to the different names 'stuck routes' and 'ghost routes' for this phenomenon at the beginning of the post. Thanks for the pointer!
“Interested in repeating this analysis for 2018 world cup?”
Hi Dan, we have no plans of repeating this analysis this time. This type of signal is still there, see for instance https://twitter.com/search?q=%40ohohlfeld%20%23worldcup&src=typd for a couple of graphs that show the impact in various places.
“@emileaben Rather than standardizing human-readable output format, why not emitting a standard structured format, separating the network part (traceroute) and the visualisation part (a tool using the structured output format). Such a format already exists, in RFC 5388. I let you do the same in JSON :-)”
thanks for the interest in the topic Stephane. You hit the nail on the head, the main idea was to standardise a structured format for traceroute. I notice a lack of enthusiasm for RFC5388, probably due to it's verbosity. quick test shows that gzip compression of RFC5388-style results would need 3x more storage relative to plain-text traceroute results. But the RFC is likely very useful to see if we cover all bases in a slimmer structured output format.
One other activity that may be worth mentioning here: We organised a get-together for traceroute implementers. As many traceroute implementations do things slightly different, a bit more coordination can help in making things more consistent, for instance in output formats.
“I'm trying to work with the ixp-jedi tool. In this step: ## measure.py This script runs one-off measurements for the probes specified in _probeset.json_ and stores their results in _measurementset.json_ This uses the RIPE Atlas measurement API for measurement creation, And it needs a valid measurement creation API key in ~ / .atlas / auth When trying to execute the script ./measure.py I get the following and I do not know how to solve it. Authentication file /root/.atlas/auth not found Please, I need your help.”
hi, thanks for trying to use the tool. i hope the docs on github are clear enough: https://github.com/emileaben/ixp-country-jedi/#measurepy --- This script runs one-off measurements for the probes specified in probeset.json and stores their results in measurementset.json This uses the RIPE Atlas measurement API for measurement creation, and it needs a valid measurement creation API key in ~/.atlas/auth . For more information on RIPE Atlas API keys see https://atlas.ripe.net/docs/keys/ --- if not let me know how to improve that. if you are interested in country-level monthy runs. these are available at: http://sg-pub.ripe.net/emile/ixp-country-jedi/history/
“Hi, Is there a way to download multiple days dataset without having to do them individually? Also do you have any API's which will permit me to download the datasets using wget?”
Hi Meenakshi, I think you'll have to download the files individually. I think, if your RIPE Access account doesn't have 2 factor authentication, you can use wget to download the files with the --user and --password options.
While we were busy pushing this post out, it looks like the Gambian Internet was restored, roughly around 12h UTC on 2 December. RIPE Atlas probes came online again, and we see 6 out of 7 ASNs in RIS data again.
