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.
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).
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.
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.
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.
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.
This article summarises today's RIPEstat demo session, including new features, changes and improvements. At the end of the article you can find the date of the next demo, and options for providing feedback.
As announced earlier on RIPE Labs, the RIPE Database mobile application (called RIPE DB Mobile) has now been released. Please find more details in the article below.
As announced earlier, the RIPE NCC is going to measure World IPv6 Day. This article details the measurements we intend to do.
A year ago we introduced IPv6 RIPEness - a system that rates IPv6 deployment of Local Internet Registries based on certain criteria. It was meant to encourage LIRs to deploy IPv6. Now, one year later, we are proud to present the progress of this project.
