In this article I look at four different IPv6 destinations in different BGP set-ups and how these are seen by RIPE Atlas probes. This reveals some differences in reachability for the different networks, likely due to BGP route filtering. We see roughly 1% out of ~500 RIPE Atlas probes that can't reach a destination in an IPv6 /48 prefix (without a covering shorter prefix) out of IPv6 PA space, likely due to filtering.
The fifth RIPEstat demo of 2012 gives an overview of the news since the previous episode at the RIPE 64 Meeting in Ljubljana, and announces changes that will happen between now and the next RIPE Meeting, RIPE 65, in Amsterdam.
Now that World IPv6 Launch is weeks behind us it's interesting to look at what long-lasting effects it had.
An alternative way of looking at the prefix size distribution in IPv4 and IPv6 blocks is now available in RIPEstat as an interactive widget. Tabular visualisation and cumulative percentage representation can be used for filtering based on minimum allocation size or for general research about the usage of address space.
We've enabled RIPE NCC members to do IPv6-traceroutes from all RIPE Atlas probes to IPv6 destinations. Until now they could get the raw analysis results (text/JSON representations of traceroute results) for analysis. In this article we present a first experimental analysis and visualisation of the traceroute results.
This is the last in a series of articles in which we look at traffic statistics at Internet Exchange Points during the European Championship 2012. This time we looked at IXP traffic during the semi-finals and the final. In addition we also look back over the entire 5 weeks of matches and draw some conclusions.
To offer our members better local access to our tools and data sets, it is now possible to create API access keys in the LIR Portal. The keys can be used to grant applications and scripts access to your (private) LIR data. The Information will be fetched securely over HTTPS and can be used in your IP address management tools, for example.
A new version of the RIPEstat app for the iPad and iPhone has been released. This also allows for obsolete parts of the data API to be deprecated.
The RIPE NCC has been assigning 32-bit Autonomous System Numbers since 2007. In this article we're providing an update about the number of 32-bit ASNs being assigned and how many are visible on the Internet.
RIPE Atlas was used to perform IPv6 reachability testing before and during the World IPv6 Launch. One success story and the usage statistics lead us to the conclusion that this feature needs to remain available even after the "launch" is over.
