New on RIPE Labs: Reviewing the 2016 Leap Second
by Mirjam Kuehne 17 Jan '17

17 Jan '17

Dear colleagues, Last month we covered the 2015 leap second ahead of the insertion of a leap second at the very end of 2016. As stated previously, leap seconds can trigger poorly-tested code paths; leap second handling always unearths bugs and issues. This one was no exception!

New on RIPE Labs: Four Years of RIPE Atlas Anchors
by Mirjam Kuehne 22 Dec '16

22 Dec '16

Dear colleagues, Four years have passed since the RIPE NCC announced its plans to put RIPE Atlas anchors into production. Since the first anchors went online in 2013, we’ve been working hard to both maintain and expand the network. As a result, we currently have 238 anchors deployed across 66 countries!

RIPE Atlas Success Story: Zoom-in on Germany
by Vesna Manojlovic 12 Dec '16

12 Dec '16

Dear all, we wrote an article as an example of how cross-pollination between communities can create success. An overlap between IETF participants, RIPE Atlas users and listeners of a popular German podcast has led to growth in the deployment of RIPE Atlas probes. We are still interested in expanding this platform in areas and networks that need more coverage. For pictures & links, go here: https://labs.ripe.net/Members/becha/ripe-atlas-success-story-zoom-in-on-ger… Text is bellow. Regards, Vesna In July 2016, during the IETF meeting in Berlin, the popular "RFC podcast" had a special episode aired an interview with Daniel Karrenberg talking about the RIPE NCC and RIPE Atlas. Thanks to the podcast listeners, and with the help of promotion on Twitter, the episode prompted many, many, MANY applications for new RIPE Atlas probe hosts. Because of both summer vacations and a temporary shortage of probes, there was a delay in shipping - but when the new batch of probes arrived at our office, we started shipping them to applicants, most of whom were from Germany. Currently, with regard to the number of active probes, Germany is leading with more than 1,000. This is more than the USA, which was in the lead for the previous few years. If you want to zoom in to this success-story, you can take a look at this RIPEstat widget. There you can see that, between 22 September and 7 October, the number of activated probes jumped from 999 to 1,157. Thank you to all the hosts, in Germany and elsewhere, who are helping to build RIPE Atlas - the largest active measurements platform! Actions Although we are happy that there is so much enthusiasm in Germany, we are still interested in increasing diversity of coverage. To this end, we're looking to reach out to: - Regions, countries and areas within countries with fewer probes - Networks (ASNs) with fewer probes - Deploying RIPE Atlas anchors instead If you would like to apply for your own RIPE Atlas probe, there is a special link just for the readers of this RIPE Labs article :) If you already have a probe, and want to get in touch: - Check out the Community pages - Follow us on Twitter - Be active on the mailing list

Dear colleagues, Please find this new article on RIPE Labs by Ramakrishna Padmanabhan: Reasons Dynamic Addresses Change Rama looked at why dynamic addresses change and found ISPs that renumber periodically, most commonly every 24 hours or a multiple of 24 hours. He also found that outages influence address changes. RIPE Atlas was used for the measurements. https://labs.ripe.net/Members/ramakrishna_padmanabhan/reasons-dynamic-addre… Kind regards, Mirjam Kuehne RIPE NCC

Shall we continue non-public measurements in RIPE Atlas?
by Mirjam Kuehne 18 Oct '16

18 Oct '16

Dear colleagues, "Non-public measurements" is a feature of RIPE Atlas that allows users to use the infrastructure to measure things while not sharing those results with the public. Is that still a useful feature? Should it exist in the future? For more details, see this new post on RIPE Labs: https://labs.ripe.net/Members/kistel/non-public-measurements-in-ripe-atlas Please also take the polls at the end of the article.

New on RIPE Labs: All Quiet in the IPv4 Internet?
by Mirjam Kuehne 21 Sep '16

21 Sep '16

Dear colleagues, Please find this new article on RIPE Labs by Philipp Richter: All Quiet in the IPv4 Internet? The number of new IPv4 allocations has stagnated, address markets have taken off, and address sharing mechanisms (for example, Carrier-Grade NAT) are on the rise as operators try to squeeze the most out of their IPv4 address space. But what is really happening in the IPv4 address space? Measuring address space activity at scale is difficult. There’s really no single vantage point that can capture all the activity.
