New on RIPE Labs: Preparing for the 2016 Leap Second
by Mirjam Kuehne 15 Dec '16

15 Dec '16

Dear colleagues, On 31 December this year, we're scheduled for another leap second. There are many stories about what leap seconds can do to infrastructure and applications, and rituals are built up around them. Please read more on RIPE Labs in an article contributed by our new colleague Stephen Strowes: Preparing for the 2016 Leap Second https://labs.ripe.net/Members/stephen_strowes/preparing-for-the-2016-leap-s… Kind regards, Mirjam Kuehne RIPE NCC

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

by Mirjam Kuehne 29 Nov '16

29 Nov '16

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.

Two weeks left to join RIPE NCC IXP Tools Hackathon, 22-23 October, Madrid
by Vesna Manojlovic 02 Sep '16

02 Sep '16

Dear colleagues, together with Euro-IX, Comcast and ISOC, the RIPE NCC is hosting a hackathon focused on developing tools for Internet Exchange Points (IXPs), in the weekend before RIPE73, in Madrid: https://atlas.ripe.net/hackathon/ixp-tools/#!the-event While the past three hackathons have specifically focused on RIPE Atlas, this event will include other data sources as well, such as: the Routing Information Service (RIS) and the PeeringDB. We will work on existing software tools that deal with IXP-data-integration in order to solve some of the challenges that operators have when making peering decisions, and to illustrate the impact of IXPs on the Internet routing and connectivity. We are looking for designers and developers, students and network operators, and of course colleagues from IXPs, to work together on hacking the new & old toolsets and visualizations! All source code developed during the hackathon will be publicly licensed and available on GitHub, and will be free for the entire community to use. -------------------- How to Apply -------------------- Interested? Learn more and apply online today! https://atlas.ripe.net/hackathon/ixp-tools/#!application-form *The application deadline is 15 September* Thanks to our generous sponsors, there is a (limited) travel funding available for certain categories of applicants. Please find more information in this RIPE Labs article: https://labs.ripe.net/Members/suzanne_taylor_muzzin/announcing-the-ixp-tool… We look forward to seeing you there!

2nd call for presentations RIPE 73
by Benno Overeinder 22 Aug '16

22 Aug '16

Dear colleagues, Please note the approaching deadline of 28 August 2016 for RIPE 73 plenary programme submissions. You can find the CFP for RIPE 73 below or at https://ripe73.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 73 will take place from 24-28 October 2016 in Madrid, Spain. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 73. See the full descriptions of the different presentation formats, https://ripe73.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 28 August 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Internet of Things (IoT) Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe73.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe73.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/
