After 3 updates and a lot of progress on IPv6 in general, it is time to think about the next version of the IPv6 CPE survey. With an increased deployment of IPv6, we are seeking a way to make it easier for you to provide feedback and to present the data in a more structured way.

For 20 years, the RIPE NCC counted the number of hosts in its service region. The Internet has grown dramatically since then and there are various ways to measure that growth. The article below describes the history of the Hostcount, the challenges we faced over the years and the reasons why we int…

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.

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…

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.

In the early days of the Internet, many organisations received very large amounts of address space. Some of it has not been used and is not visible on the Internet. As the RIPE NCC's pool of available IPv4 address space nears depletion, we are actively encouraging holders of unused unannounced spac…

This artlce looks at the results of a recent survey that was conducted to find out which network security methods are currently in place and how operators are preparing for the introduction of Resource Public Key Infrastructure (RPKI). As part of the study, we also conducted interviews with a numbe…

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.
