Public RIPEstat Demo Session Etiquette
Mirjam Kühne — Jan 20, 2011 12:00 AM

When joining the monthly public RIPEstat demo sessions, please note the following points of etiquette. This will make communication via webex easier for all participants.

The RIPE NCC and the World IPv6 Day
Mirjam Kühne — Jan 19, 2011 02:35 PM

The RIPE NCC supports the World IPv6 Day scheduled for 8 June 2011. Read more about plans for the event and the role that the RIPE NCC will play.

Industry Comparison 2: The Internet and the Financial Industry
Tom Vest — Jan 18, 2011 05:25 PM

This is the third in a series of articles about the structure of the ISP industry within the RIPE NCC service region. This time we compare the distribution of RIPE NCC IPv4 addresses to the distribution of reserve assets across banks and financial institutions that report to the European Central Bank.

RIPE Atlas - the iPad Drawing
Emile Aben — Jan 14, 2011 03:15 PM

This article is about the lottery of an iPad for people hosting RIPE Atlas probes. As an extra motivator for people to keep their probes up as much as possible, the lottery drawing is weighted based on probe-uptime.

GRS Sources and the RIPE Database API
Paul Palse — Jan 11, 2011 02:40 PM

A while ago we announced the new Global Resource Service (GRS) for the RIPE Database. It allows you to query other Regional Internet Registry (RIR) databases and Routing Registry data using the RIPE Database interface. In this article we describe this service some more and show some examples.

RIPE NCC Hostcount
Mark Dranse — Jan 04, 2011 02:30 PM

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 intend to stop doing the Hostcount as of January 2011.

ASN Ranking Correlations Between Spam Blocklists
John S. Quarterman — Dec 23, 2010 10:10 AM

Comparing ASN rankings by spam volume from two different data sources, CBL and PSBL (with a side trip to the University of Texas Computer Science Department), indicates there is enough correlation to have confidence in the rankings.

Routing Certification Beacons
Mark Dranse — Dec 21, 2010 10:02 AM

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 — Dec 20, 2010 05:45 PM

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 objects match the prefixes announced in the BGP routing tables?

How Does the Internet Industry Compare?
Tom Vest — Dec 09, 2010 09:15 AM

Second in a series of articles about the structure of the ISP industry within the RIPE NCC service region. This time we try to identify criteria that make other economic sectors comparable to our own industry. We then test our assumptions by exploring a very simple comparison to the global automotive manufacturing sector.
