Sending and Receiving Emails over IPv6

Mirjam Kühne — Apr 10, 2014 11:15 AM

Sending and Receiving Emails over IPv6 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?

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

Emile Aben — Oct 02, 2013 04:30 PM

RIPE Atlas - Packet Size Matters 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

Emile Aben — Aug 12, 2013 09:50 AM

IPv6 ASNs - Network Size Matters 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

Manish Karir — Jun 25, 2013 03:55 PM

IPv6 Internet Pollution 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

Johannes Weber — Jun 18, 2013 11:45 AM

IPv6 Security - An Overview 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

Vaibhav Bajpai — Jun 13, 2013 12:14 PM

Evaluating the Effectiveness of Happy Eyeballs 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.

IPv6 RIPEness - Implementing the Fifth Star

Emile Aben — May 12, 2013 05:30 PM

IPv6 RIPEness - Implementing the Fifth Star In this article we present the first publicly available beta version of the fifth IPv6 RIPEness star. This measures real IPv6 deployment from LIRs in the RIPE NCC service region. The methodology is what we think to be the best compromise yet between simple and fair. In this first version, 573 LIRs (>9%) qualify for the fifth star.

Networks With IPv6 Over Time - A Short Update

Emile Aben — Apr 04, 2013 03:00 PM

Networks With IPv6 Over Time - A Short Update We regularly check the status of IPv6 deployment in the RIPE NCC service region, but also in other regions. One way to measure IPv6 deployment is to look at the percentage of networks (Autonomous Systems) announcing IPv6 prefixes and to follow the developments over time.

RIPE Atlas via the LIR Portal

Vesna Manojlovic — Jan 22, 2013 09:40 AM

RIPE Atlas via the LIR Portal RIPE NCC members visit the LIR Portal to manage their IP address and AS Number resources. Now we offer easier access to a number of RIPE Atlas features from the LIR Portal. This is just the first step of more cross-platform benefits to come, made possible by logging in to your RIPE NCC Access account.
