How does the MENOG Region Measure up?
How does the MENOG Region Measure up?
Mirjam Kühne — Mar 31, 2015 08:24 PM

With the MENOG 15 meeting taking place this week, we look at Internet measurements and statistics for countries in the MENOG region.

Measuring Countries and IXPs with RIPE Atlas
Measuring Countries and IXPs with RIPE Atlas
Emile Aben — Mar 23, 2015 01:55 PM

We've been working with various Internet Exchange Points (IXPs) over the last few months to see how RIPE Atlas active measurements can provide insight into how they are keeping local traffic local. This could help to improve performance and efficiency for IXPs and their members. To explore this we've created a set of python scripts to analyse Internet traffic paths between RIPE Atlas probes in a given country, and see if we can identify if they traverse IXPs.

RIPE NCC Membership - Developments After Reaching the Last /8
RIPE NCC Membership - Developments After Reaching the Last /8
Rene Wilhelm — Feb 23, 2015 09:05 AM

On 14 September 2012, the RIPE NCC started allocating IPv4 addresses based on the last /8 policy. With more than two years passed, we look at the effects this had on membership numbers and demographics. We also look at what the last /8 policy meant for IPv6 uptake.

Year in Review and Looking Ahead to 2015
Axel Pawlik — Dec 30, 2014 03:20 PM

RIPE NCC Managing Director Axel Pawlik recently gave an interview about what he sees as the most important developments of 2014 and looks ahead to the big issues in 2015.

IPv6 to Secure Business Continuity
Marco Hogewoning — Jun 30, 2014 12:17 PM

Every few months somewhere somebody will tell you that the sky is falling and the end of the Internet is close. The reasons brought up vary through a broad spectrum from superior technology to the lack of capacity. To a large extent people in the industry have become immune to these messages, for they are either unrealistic or in cases where the threat was real, the Internet responded in its usual resilient ways, adopting to the changing environment. It is this remarkable flexibility and the constant search for optimisation that has made Internet seep into every little corner of our lives and businesses.

The IPv6 Analyser
The IPv6 Analyser
Alex Band — Jun 20, 2014 11:55 AM

The IPv6 Analyser is a toolset that offers our members a visual insight into all the allocations, aggregations and assignments they have made. It was announced a few weeks ago and we're seeing LIRs starting to use it. Please find below some more details about this tool.

Sending and Receiving Emails over IPv6
Sending and Receiving Emails over IPv6
Mirjam Kühne — Apr 10, 2014 11:15 AM

The change to IPv6 creates new challenges to keep spam out of email. Because of the sheer size of the IPv6 space, it seems more efficient to build a domain-blocking and reputation system rather than an IP-blocking system. But how do we ensure emails over IPv6 have an authenticated domain?

Report on IPv6 Security Test Methodology
Geert Jan de Groot — Apr 09, 2014 10:00 AM

The Dutch Institute for Applied Scientific Research (TNO) and a number of Dutch security companies have recently published a report on IPv6 security test methodologies.

Modifications to the IP Analyser to Reflect New Policy
Alex Band — Apr 07, 2014 10:55 AM

We are in the process of implementing the policy regarding Post Depletion Adjustment of Procedures (2013-03). In this article we will give an overview of the changes we are making to the IP Analyser web interface and API, so you can accommodate your scripts and workflow. We intend to implement these changes on 16 April 2014.

How Many RIPE Atlas Probes Can Resolve IPv6-only Domain Names?
Stéphane Bortzmeyer — Jan 13, 2014 09:05 AM

Each RIPE Atlas probe has at least one DNS resolver, indicated by a DHCP reply on the local network of the probe. Irrespective of the IP address of the resolver, this server may have IPv4 and IPv6 connectivity or only IPv4 connectivity. What is the percentage among RIPE Atlas probes?

Are We Ready to Switch Off IPv4?
Marco Hogewoning — Dec 13, 2013 10:39 AM

At the RIPE 67 meeting in Athens, Greece, the RIPE IPv6 Working Group ran a little experiment to test the feasibility of an IPv6-only network and to identify challenges in user experience. While the results were highly encouraging, they indicated that there is still work to be done before IPv4 can be switched off once and for all.

14th Saudi Arabian IPv6 Task Force Meeting
Marco Hogewoning — Nov 14, 2013 10:55 AM

The RIPE NCC recently participated in a meeting of the Saudi Arabian Task Force. A well-attended event, it included presentations and discussions about IPv6 deployment strategies, as well as presentations by operators reporting back on their successful IPv6 pilot projects and plans to roll out IPv6 in the first half of 2014.

RIPE Atlas - Packet Size Matters
RIPE Atlas - Packet Size Matters
Emile Aben — Oct 02, 2013 04:30 PM

This new RIPE Labs article talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets.

The Assisted Registry Check - Let Us Help You!
Matt Parker — Sep 24, 2013 10:25 AM

The Assisted Registry Check is the new name for the RIPE NCC’s audit activities that have been improved using feedback from RIPE NCC members and the RIPE community. This improvement aims to make the process more efficient and less time consuming for Local Internet Registries (LIRs).

IPv6 ASNs - Network Size Matters
IPv6 ASNs - Network Size Matters
Emile Aben — Aug 12, 2013 09:50 AM

This article provides statistics about how much IPv4 address space is being announced by networks (ASNs) that are also announcing IPv6 address space. Currently this is about 70% of IPv4 address space.

IPv6 Internet Pollution
IPv6 Internet Pollution
Manish Karir — Jun 25, 2013 03:55 PM

Following up from earlier experiments in which MERIT looked at pollution of IPv4 prefixes, Manish Karir and his colleagues now did an experiment with various IPv6 prefixes. The results can be found in this article.

IPv6 Security - An Overview
IPv6 Security - An Overview
Johannes Weber — Jun 18, 2013 11:45 AM

The advent of IPv6 changes not only the network components, but also the security field shifts. We see new types of attacks or at least variations of the attacks we know from IPv4. This article provides an overview of the IPv6 security vulnerabilities that arise with the launch of IPv6.

Evaluating the Effectiveness of Happy Eyeballs
Evaluating the Effectiveness of Happy Eyeballs
Vaibhav Bajpai — Jun 13, 2013 12:14 PM

The IETF has developed solutions that promote a healthy IPv4 and IPv6 co-existence. The happy eyeballs algorithm for instance, provides recommendations to application developers to help prevent bad user experience in situations where IPv6 connectivity is broken. We study the effectiveness of the happy eyeballs algorithm.

How Many RIPE Atlas Probes Believe They Have IPv6 (But Are Wrong)?
Stéphane Bortzmeyer — Jun 11, 2013 04:15 PM

To check the connectivity of an IPv6 device with RIPE Atlas, one typically asks N probes to ping the target and deduces the reachability of the target from the percentage of failures. But RIPE Atlas probes, like many IPv6 devices, often believe they are IPv6-connected while they are not.
