Measuring World IPv6 Day - Some Glitches And Lessons Learned
Emile Aben — Jun 28, 2011 10:25 AM

As already stated by us and others, World IPv6 Day on 8 June, was a big success. No major issues came to light, and most minor issues that surfaced were resolved, and as such were a useful learning experience. In this article we provide details on some of the events we observed by looking at our measurement data.

World IPv6 Day took place on 8 June 2011. The RIPE NCC did a number of measurements both before and during World IPv6 Day. We've done an initial analysis of the data and would like to share our first impressions and results with you.

RIPE NCC and BBN have been working on measuring the impact of 6to4 on the latency of Internet traffic. This article describes the measurement techniques used for this survey, and some initial findings based on measurements conducted at BBN.

Experimental NAT64/DNS64 Service

Raimundas Tuminauskas — Jun 01, 2011 04:30 PM

The Lithuanian research and education network LITNET has introduced the NAT64/DNS64 service at the TERENA Networking Conference (TNC2010) last year, and it has been running ever since. The main feature of NAT64/DNS64 is that it can not only be used as a usual NAT, but as a meeting point between two networks. The service is open to anyone wishing to try an IPv6-only setup (subject to the compliance with our acceptable use policy).

When Does World IPv6 Day Start?
When Does World IPv6 Day Start?
Emile Aben — May 31, 2011 02:45 PM

World IPv6 Day is on 8 June 2011. On this day, a lot of organisations, including some of the most popular ones like Google, Yahoo and Facebook, are going to provide IPv6 addresses for AAAA queries for their websites. This will make content available over IPv6 for one full day. Since DNS responses are often cached, some users won't see this change immediately. In this article we look at how DNS caching affects the start of World IPv6 Day, and how World IPv6 Day participants can minimise these effects.

World IPv6 Day - IPv6 Eye Chart

Emile Aben — May 27, 2011 10:30 AM

The RIPE NCC is doing some measurements for World IPv6 Day. One of them is the IPv6 eye chart, a web page that allows you to test your connectivity to selected dual-stacked web sites and World IPv6 participants. The goal is to see if an end user has connectivity problems to dual-stacked websites. This is an increasingly rare problem, but still perceived important enough to prohibit content providers to go dual-stack.

RIPE Atlas - First Results
RIPE Atlas - First Results
Robert Kisteleki — May 24, 2011 06:05 PM

Since the first RIPE Atlas probes we handed out at the RIPE Meeting in Rome in November 2010, a lot of progress has been made. There is a lot of interest in these probes and in the measurement results. We were happy to see that we surpassed our original goals quite quickly. Now the number of probes out there is sufficient to look at first results.

IPv6 CPE Survey Results - May 2011
IPv6 CPE Survey Results - May 2011
Marco Hogewoning — May 23, 2011 10:10 AM

A couple of months ago we announced that we were going to redo the IPv6 CPE survey. Based on your feedback, a real survey was released at the end of April 2011. So far we have received over 100 responses. We'll keep the survey open to gather more information, but for now we would like to share some initial results with you.
