How are you Deploying IPv6? Take this Survey

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.

Developments in IPv4 Transfers

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?

New RIPE Atlas APIs

We've updated the RIPE Atlas APIs - and there's a comprehensive new manual to explain how to use them. As a result, the current (version 1) APIs are still available for now, but will be deprecated by the end of the year.

There is Gold in this Stream - Sifting Through Used RIPE Atlas Traceroute Results

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.

Fragmenting IPv6

The design of IPv6 represented a relatively conservative evolutionary step of the Internet protocol. Mostly, it's just IPv4 with significantly larger address fields. Mostly, but not completely, as there were some changes. IPv6 changed the boot process to use auto-configuration and multicast to perform functions that were performed by ARP and DHCP in IPv4. IPv6 added a 20-bit Flow Identifier to the packet header. IPv6 replaced IP header options with an optional chain of extension headers. IPv6 also changed the behaviour of packet fragmentation. Which is what we will look at here.

The Internet for Things

Please read this guest post by Byron Ellacott, Senior Software Architect at APNIC: The Internet of Things without the Internet is just things, and we’ve had things since the first caveman used a pointy stick to draw on a wall. What then does the Internet bring to things to justify a capital T?

Connectivity in the LAC Region

Please enjoy this guest post by Agustín Formoso, Software Developer at LACNIC: Regional connectivity is not an easy metric to measure. To do it properly you need measurements generated by multiple vantage points, located in as many places as possible (both geographically and logically). Besides, connectivity is not something strictly defined, as it has no standard definition (as opposed to many metrics we use in today’s Internet).

How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs

RIPE Atlas back-end applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs.
