Interesting Graph - IPv6 Performance
• 2 min read
This graph shows IPv6 performance as measured to www.ripe.net. These measurements show performance of native IPv6 on average being very close to IPv4.

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
• 1 min read
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.
Interesting Graph - Decrease in 6to4?

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 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 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 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…
“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.
