One way to determine the denseness of the Internet, or its “interconnectedness”, is to look at the path length between Autonomous Systems (ASes). And are there any differences visible when looking at IPv4 or IPv6 networks? See our findings in this article.

Olivier Crepin-Leblond from the Internet Society chapter in England is announcing the results of a tool they designed and implemented. It is an “IPv6 crawler" that crawls through the DNS to detect IPv6 compliant servers. The results were interesting and can be viewed on an "IPv6 Matrix" showing IP…

The RIPE NCC has launched the RIPE Data Repository, a ‘portal’ that hosts a collection of data sets useful for scientific and operational Internet research. The repository can hold up to 100TB of diverse sets of data, some going back as far as 1993.

As promised we publish an updated version of the IPv6 CPE survey and matrix as soon as we have additional information. Below you'll find the most up-to-date matrix, including data we received from some of the vendors in the meantime.
Guido van Rossum sent me an email saying: "I'm glad you're taking up this subject. I like that you wrote up some of the negative responses you received -- I've seen those too, and I think it's pretty normal to see a range of responses. But that doesn't mean you can't make progress! We can't fix our biases if we're not aware of them, and sometime you have to start by over-compensating just to end up in the right place eventually."
“Never heard of a DNS query type AAA before. Is that IPv5 protocol?”
Haha. Thanks, for pointing this out. It's fixed now.
“Where can I find the IPv4 space amount that RIPE hold ?”
Yi, If you go to this page https://labs.ripe.net/statistics/?tags=ipv4 and scroll all the way to the bottom, you will see the number of remaining IPv4 addresses. If you click on the title of the graph, you wil see another pge with more information about the RIPE NCC's available IPv4 address pool. Please let us know if you have any more questions.
