K-root Reachability in the Middle East and Central Asia
Babak Farrokhi — 27 Jun 2016

There are about 600 DNS root server instances deployed around the world. But does everyone have an equal level of access to a root server in their region? Are they fairly distributed? Do all major (and country level) network operators recognise the value in deploying (or peering with) a root server in their network?… Read more

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.… Read more

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.… Read more

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?… Read more
