The Next 42 RIPE Atlas Probes at Hackerspaces

In this article, we give one example of the possible communities that are now easier to build around RIPE Atlas probes. With the tagging of similar probes, existing communities can use additional tools for creating and analysing RIPE Atlas measurements, such as "IXP Country Jedi", to create their own interpretation of the available data. We are hoping this is going to be an inspiration to the reader, and an invitation to play with the results and improve on the code.

15,000 Local Internet Registries

On 28 December 2016, about 90 days before its 25th anniversary, the RIPE NCC reached the milestone of serving 15,000 active Local Internet Registries (LIRs). In this article we look at trends observed in the membership in the last few years. We also assess the remaining lifetime of the last bit of IPv4 in our available pool.

Studying the IPv4 Transfer Market: Reported Transfers

Over the past five years, all Regional Internet Registries (RIRs), with the exception of AFRNIC, have exhausted their pool of available IPv4 addresses. The Internet community anticipated this almost two decades ago and standardised IPv6 as a long-term solution. IPv6 uptake is, however, still lagging. Hence, affected businesses have actively started seeking stop-gap measures to prolong the lifetime of IPv4 addresses.

50 Shades of NAT

As a friend once told me, “there's a fine line between pleasure and pain.”* There's a vast body of literature to corroborate that story, not including the 100+ million copies of the book referred to in the title of this piece. But what does that have to do with Network Address Translation (NAT)? Could the reason we all love our NATs be that they're the network engineer’s guilty pleasure? How long before we permanently cross the threshold and are confronted with the painful reality of NAT's dark downsides?

Preparing for the 2016 Leap Second

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. Such rituals stem from reality: leap seconds trigger poorly-tested code paths and run contrary to assumptions that system time always runs in one direction. It's useful to be aware of how your infrastructure handles leap seconds and how NTP servers handle them, so you can plan around the event. Here, we look at some of the NTP measurements the RIPE Atlas platform took around the last leap second, and approaches for handling them.

RIPE Atlas Success Story: Zoom-in on Germany

Here is an example of how cross-pollination between two or more 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 (hardware devices that measure Internet infrastructure). We are still interested in expanding this platform in areas and networks that need more coverage.

Ambassador, You Are Spoiling Us

At the RIPE NCC, we are grateful for the contribution RIPE Atlas ambassadors make to the success of the RIPE Atlas measurements platform. In this article, we focus on a handy RIPEstat tool that can be used to visualise the results of their efforts. The tool provides a historical view of country-specific growth of RIPE Atlas probe numbers and allows for comparisons of up to four countries in the same graph.
