Evaluating IPv4 and IPv6 Packet Fragmentation
Evaluating IPv4 and IPv6 Packet Fragmentation
Geoff Huston — Jan 29, 2016 10:35 AM

One of the more difficult design exercises in packet-switched network architectures is that of the design of packet fragmentation. In this article, I’d like to examine IP packet fragmentation in detail and look at the design choices made by IP version 4, and then compare that with the design choices made by IP version 6.

Behind the Curtain: Making IPv6 Work
George Michaelson — Jan 26, 2016 12:55 PM

Wouldn’t it be nice if turning on IPv6 really was ‘press one button and the rest is magic’ easy?

Christmas Gift Idea: Some IPv6 Experience
Christmas Gift Idea: Some IPv6 Experience
Marco Hogewoning — Dec 14, 2015 09:25 AM

The holiday season is rapidly approaching and this year is coming to a close, another one done and another one that seen some great and wonderful and also unfortunately some sad moments. One of those key moments was the depletion of the IPv4 pool in the ARIN region, which for some probably means the sad realisation that their business models will hit a growth barrier.

Examining IPv6 Performance
Examining IPv6 Performance
Geoff Huston — Nov 26, 2015 10:57 AM

Every so often I hear the claim that some service or other does not support IPv6 not because of some technical issue, or some cost or business issue, but simply because the service operator is of the view that IPv6 offers an inferior level service as compared to IPv4, and by offering the service over IPv6 they would be exposing their clients to an inferior level of performance of the service. But is this really the case? Is IPv6 an inferior cousin of IPv4 in terms of service performance?

Lost Stars - Why Operators Switch off IPv6
Lost Stars - Why Operators Switch off IPv6
Nathalie Nathalie — Nov 18, 2015 08:40 AM

One of the measurements that we have been running for a long time is IPv6 RIPEness, where we measure the IPv6 activity of our members. We award our members with stars if they (for example) announce their IPv6 allocation in the global routing table.

RIPE NCC Membership Statistics Q3 2015
RIPE NCC Membership Statistics Q3 2015
Rene Wilhelm — Oct 30, 2015 08:40 AM

We look at the RIPE NCC in terms of growth, geographic distribution and IPv6 deployment. We find that recent RIPE policy changes have had an impact on membership statistics and development trends.

Tony Smith from APNIC is looking at the increase in IPv6 deployment now ARIN depleted their free pool of IPv4 addresses.

Checking your Internet Connectivity with RIPE Atlas Anchors
Checking your Internet Connectivity with RIPE Atlas Anchors

If you monitor your external Internet connectivity, you may wonder which machine is the best to ping. Hesitate no more - you can use RIPE Atlas anchors as landmarks.

IPv6 Deployment in Estonia
IPv6 Deployment in Estonia
Tarko Tikan — Jun 04, 2015 11:25 AM

Some time ago, many people noticed rapid IPv6 deployment growth in Estonia (from 0% to 5% in 4 weeks). Tarko Tikan, from 3249/Elion/Estonian Telecom, explains the reason behind this.

Usage of Teredo and IPv6 for P2P on Windows 10 and Xbox One
Mirjam Kühne — May 22, 2015 01:49 PM

Please find below a guest post by Darrin Veit and Christopher Palmer who originally posted this to the NANOG mailing list. It provides information for Xbox One, but also shares some relevant details on upcoming Windows functionality in terms of Teredo and IPv6 usage.

How Does the MENOG Region Measure Up?

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 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 try to identify whether 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.
