Anycast vs. DDoS - Evaluating the November 2015 Root DNS Event
Anycast vs. DDoS - Evaluating the November 2015 Root DNS Event
Giovane Moura — 31 May 2016

IP anycast has been widely used to replicate services in multiple locations as a way to deliver better performance and resilience. It has been largely employed by CDNs and DNS operators, such as on the root server system. However, there is little evaluation of anycast under stress.

How are you Deploying IPv6? Take this Survey
Jordi Palet Martinez — 31 May 2016

After 15 years conducting training on IPv6 in over 110 countries, I’ve been asked all sorts of questions. “How do I use my IPv6 addressing space?” “What prefix size should I provide to customers?” Although I have answers to these and many other best practice related questions, the one question, which I have not been able to answer to the best of my ability, is “What is the approach of other ISPs?”. So I decided to find out.

A Visual Impression of Probe Lifetimes
A Visual Impression of Probe Lifetimes
Philip Homburg — 25 May 2016

For a while now, the number of active RIPE Atlas probes has hovered around the 9,400 mark. This means that new probes are being connected at a fast enough rate to replace failing probes, but not enough to grow the network. At the same time, the version 3 probes have problems with their USB sticks. This led us to wonder whether these two issues are related.

Developments in IPv4 Transfers
Developments in IPv4 Transfers
Rene Wilhelm — 24 May 2016

In May 2015, we looked at IPv4 transfers in the RIPE NCC service region and found signs of an emerging market. Both the number and size of transfers conducted under RIPE Policy showed an upward trend in the years 2013-2014. One year later, we take another look. Did this trend continue? What have been the effects of the inter-RIR transfer policy?

Draft RIPE Chair Election Procedure
Hans Petter Holen — 23 May 2016

When Rob Blokzijl stepped down, he handed over the role as Chair of RIPE to me in the closing plenary of RIPE 68 in Warsaw, 16 May 2014. Rob had been the RIPE Chair for 25 years since 1989 and there has not been any procedure for selecting the Chair. Rob tasked me to put in place a procedure to elect my successor.

There is Gold in this Stream - Sifting Through Used RIPE Atlas Traceroute Results
There is Gold in this Stream - Sifting Through Used RIPE Atlas Traceroute Results
Daniel Karrenberg — 20 May 2016

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 great potential for studying the packet layer of the Internet in general and for providing tools to network operators in particular. All this suggests a large and diverse potential for further work.
