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.
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.
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.
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.
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.
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 objects match the prefixes announced in the BGP routing tables?
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.
Imagine a tool designed to show what's happening on your network in near real time. TC Console is a tool that allows you to do that, but with a crucial new innovation: it integrates Team Cymru's unique insight into malicious activity on the Internet.
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.
