RIPE Chair Selection - Next Steps
Please find below an update from the RIPE Nominating Committee. Three of the NomCom members answer some of the questions you might have about the next steps in the selection process.
25 Years of the RIPE NCC – The First Hours
March 1992 - NIKHEF Amsterdam - Main Computer Room: "We have connectivity!" Marten called out. "Running the check script." Daniel responded. The two young engineers were intently looking at their screens, totally oblivious to anything around them: the noise of the air-conditioning fans, the bli…
There is Gold in this Stream - Sifting Through Used RIPE Atlas Traceroute Results
This work demonstrates the value of the results collected by RIPE Atlas independent of the original purpose for collecting them. Using all traceroute results from a particular day as an example, we first show that near real-time analysis of the result stream is feasible. Then we show that this has …
RIPE Atlas Fun: Map a RIPE Atlas Anchor
View maps based on RIPE Atlas traceroute measurements. Compare the maps to the ISP's description of their topology. See the potential of RIPE Atlas for mapping the packet layer topology. Learn about experimental tools you can use yourself to explore. Make suggestions for further work.
Conclusions Drawn from Reverse DNS Event
On Wednesday 13 June 2012, an unknown error caused the removal of several zone files from the configuration of our reverse DNS provisioning system. Following up from the initial report published on RIPE Labs, we further analysed what caused the incident and implemented a number of procedures to dec…
Registration History for Members - A Demo
RIPE NCC members can browse RIPE database objects with history in RIPEstat for a couple of weeks as a demonstration. Please check it out and let us know what you think.
Root Servers in Member Networks
In addition to the existing global and local instances of K-root, we propose member instances of K-root. This article describes the benefits and how this will be implemented during the pilot phase.

Timeline of Reverse DNS Events
Last week there were several problems with the RIPE NCC's reverse DNS (rDNS) service. This article is a first report about the events. It is not intended to analyse the causes or make detailed recommendations for action.
IPv4: Business As Usual
In anticipation of reaching the last /8 of IPv4 addresses in the RIPE NCC service region, we have been looking at the number of IPv4 addresses the RIPE NCC handed out over the last four years. The curves look surprisingly uniform.
I cannot resist to point out that the privacy policy on the web site of this initiative says: 'Privacy Policy coming soon'.
“I think it’s a must-have to support presenters and chairs using open standards to stream their content. An open internet is not governed through propriety interfaces.”
Definitely! Any pointers to an open standard solution with similar or even acceptable performance? I am sure the RIPE NCC meeting team is all ears.
Great work. Thanks for sharing including what went wrong! It is really good to hear that we can deliver a stream with <10s delay. I am just curious how much AWS cost per viewer per day. A very rough estimate is fine.
Haris, I do not recall meeting you but that means very little. This was a period of many many things happening at the same time. I have helped many ccTLDs in the late 80s and early 90s. I'll get in touch privately and we will figure it out.
“Looks like I'm missing the requirements for attending enough ripe meetings lately. That rule does hampers the diversity requirements.”
Hoi Jaap, Yes that can be frustrating. However it is one of those rules that we should not change for pragmatic reasons while the process is running. Any eligibility criterum will reduce diversity somehow. I have had a couple of similar comments privately from people I would consider an asset to the NomCom. The ' three out of five meetings' criterium is based on research described in appendix M of ripe-728. It is a good idea to discuss this as part of the community evaluation of this first NomCom process. I plan to point this out in the NomCom report.
“Hello, my name appears to be missing in the list together with the number 11, probably a cut-and-paste mistake (last line missing in the list). Greetings, Wolfgang”
Hello Wolfgang, indeed your name is missing. My mistake! Apologies. We have also gained one more volunteer since Friday. Here is the current list: 07 Alexander Isavnin Internet Protection Society 19 Andreas Wkittkemper Verizon Deutschland GmbH 10 Antonio Prado SBTAP 27 Arnold Nipper DE-CIX Management GmbH 16 Benno Overeinder NLnet Labs 11 Brian Nisbet HEAnet 03 Cosmin Octavian Lupu Visma 18 Dmitry Burkov RU-CENTER 09 Dmitry Kohmanyuk Hostmaster.UA 08 Frederic Jaeckel GitHub, Inc. 26 Geoff Huston APNIC 25 Gert Döring SpaceNet AG 24 Hervé Clément Orange SA 22 Jim Reid RTFM llp 23 Joe Abley Public Interest Registry 06 Keith Mitchell DNS-OARC 15 Marcus Stoegbauer Megaport / ECIX 04 Markus de Brün BSI 30 Martin Winter Network Device Education Foundation (Net 07 Massimo Candela NTT 14 Mircea Ulinic DigitalOcean 02 Nathalie Trenaman RIPE NCC 01 Nurani Nimpuno Asteroid International 21 Ondřej Caletka CESNET 13 Pascal Gloor Quickline AG 20 Paul Hoogsteder Meanie 28 Randy Bush Arrcus Inc & IIJ & RGnet 31 Robert Evans Jisc 32 Sander Steffann Global NOG Alliance 29 Stefan Wahl Megaport / ECIX 05 Tina Morris Amazon 33 Wolfgang Tremmel DE-CIX Management GmbH 12 Wolfgang Zenker punkt.de GmbH
Good point. I wonder whether other readers have experiences with shells around cloud services that provide some degree of provider independence?
Our region is in no way special in this regard. ARIN for instance is experiencing much the same. It won't be long before RIPE NCC staff will be called to give evidence in some criminal court somewhere. We better be ready! https://teamarin.net/2019/05/13/taking-a-hard-line-on-fraud/
Thank you for this report. I have a couple of questions: Have you tested the impact of VM performance on measurements? In particular have you implemented performance reporting that would allow us to detect if measurements are impacted by VM performance problems? Are there draft requirements for anchor VMs and do they consider VM performance? As you mention scaling the back-end and support infrastructure may become a problem if the investment of the host becomes very low. Have you considered asking the hosts of VM anchors to contribute to these costs? Daniel
Who is Vint Cert? ;-)
