In January 2011, the RIPE NCC will announce the production launch of the resource certification system. We made some extensions to the BGP beacons which we provide as a part of the Routing Information Service to assist network operators.

Interesting Graph - How Accurate is the RIPE Routing Registry?

Rene Wilhelm

• 20 Dec 2010

• 5 min read

Last month we published a graph that shows how complete the RIPE Routing Registry really is. How many of the organisations that receive an Autonomous System Number (ASN) from the RIPE NCC use the RIPE Routing Registry to register their route objects. The results were encouraging. But do these route…

6to4 - How Bad is it Really?

Emile Aben

• 1 Dec 2010

• 6 min read

At the recent RIPE 61 meeting in Rome and at earlier meetings, we heard that connectivity over 6to4 is not very dependable, which hampers IPv6 deployment. I wondered how bad it really is and started measuring it. This article describes what I measured and shows the results. Spoiler: It's pretty bad.

Interesting Graph - AS Path Lengths Over Time

Mirjam Kühne

• 25 Oct 2010

• 4 min read

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.

• 5 min read

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…
