Dear colleagues, For those of you who missed Razvan C. Oprea's presentation during the MAT-WG in Athens, we put a summary report on RIPE Labs: How “National” is the Dutch Critical IP Infrastructure? https://labs.ripe.net/Members/benno_overeinder/dutch-critical-ip-infrastruc… This is a contribution by Benno Overeinder, Fahimeh Alizadeh and Razvan C. Oprea. Kind regards, Mirjam Kuehne RIPE NCC

Traceroute visualisation
by Mike Hughes 18 Oct '13

18 Oct '13

Good talk by Emile on visualisation of traceroutes and the various sources of geo-loc that can be munged and derived to try and give more accurate info. While there was talk of commercial geo-loc such as Maxmind, what about mining the DNS for LOC records? Has there been any investigation of that? Or am I just an ossified dinosaur, talking about LOC records? :) Cheers, Mike

Ambient measurements
by Richard Barnes 18 Oct '13

18 Oct '13

Hey all, As a follow-up to Mikael's point in AOB at the MAT meeting today (that there are lots of statistics already being kept by hosts, e.g., in TCP stacks): I did a presentation at the IEPG back at the Beijing IETF about the idea of standardizing a "Network Measurement Reporting" language, so that things like ping and traceroute could share their results with the rest of the Internet. <http://iepg.org/2010-11-ietf79/NMR-IEPG.pdf> It's long enough ago that I don't remember precisely what the feedback was. But no further work got done, so it probably wasn't that positive :) Nonetheless, I continue to think that collecting ambient measurement data is a really interesting idea, so it would be cool to hear what others here think. Cheers, --Richard

Completed Migration of RIS Visualisation to RIPEstat

Completed Migration of Routing Information to RIPEstat Dear colleagues, We have now successfully completed the planned* migration of RIS data visualisation to RIPEstat: http://stat.ripe.net Our Routing Information Service (RIS) has been collecting global BGP routing information for over 12 years. During this period, many different interfaces to analyse and visualise accumulated data have been developed. Therefore, we have centralised access to the RIS interfaces and tools, and decommissioned some of the outdated interfaces and the old backend. This is in line with our long-term goal to provide more consolidated services, as communicated previously by our Chief Information Officer, Kaveh Ranjbar, in his article, "The Future of RIPE NCC Technical Services": https://labs.ripe.net/Members/kranjbar/future-of-ripe-ncc-technical-services More information about the migration of RIS data visualisation to RIPEstat is available on RIPELabs: https://labs.ripe.net/Members/fatemah_mafi/improved-routing-information-ava… Please submit any requests for additional features via email to stat(a)ripe.net so that we can add these to the RIPEstat Roadmap and include them in our planning: http://roadmap.ripe.net/ripe-stat/ We look forward to your feedback. Regards, Vesna * The original announcement and the reminder can be found at: http://www.ripe.net/ripe/mail/archives/mat-wg/2013-August/000323.html http://www.ripe.net/ripe/mail/archives/mat-wg/2013-September/000350.html

Announcing RIPE Atlas Service Terms Documentation for Anchor Hosts
by Vesna Manojlovic 03 Oct '13

03 Oct '13

Dear colleagues, In the process of transitioning RIPE Atlas anchors towards being a production service, we have developed two documents that describe the service terms: - Draft RIPE Atlas Service Terms and Conditions - Memorandum of Understanding - Hosting a RIPE Atlas Anchor Probe Please see the details in this RIPE Labs article: https://labs.ripe.net/Members/becha/ripe-atlas-anchors-terms-and-conditions If you are currently hosting an anchor, or if you are interested in hosting a RIPE Atlas anchor in the future, we would like to hear any feedback you have on these draft documents. Our goal is to finalise the documents by 11 October so that we can announce the production service at the upcoming RIPE 67 Meeting in Athens.

New on RIPE Labs: RIPE Atlas - Packet Size Matters
by Mirjam Kuehne 02 Oct '13

02 Oct '13

Dear colleagues, This new RIPE Labs article (contributed by Emile Aben) talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets. Please find the detailed results on RIPE Labs: https://labs.ripe.net/Members/emileaben/ripe-atlas-packet-size-matters Kind regards, Mirjam Kuehne RIPE NCC
