Phase out of Reply-Size Tester
Wolfgang Nagele — Sep 07, 2010 10:00 AM

Back in December 2009 we released a tool with which you can test your DNS resolver for possible issues with a DNSSEC signed root zone. Now that the root zone has been signed in production since 15 July 2010 we will stop this service on Monday, 11 October 2010.

DNS Clients Do Request DNSSEC Today
Daniel Karrenberg — Sep 06, 2010 11:05 AM

After the DNS root zone was finally signed and a number of TLDs began signing their zones, we were curious to see how many clients actually request DNSSEC information. First we looked at our server that provides secondary service to several ccTLDs.

A short story about ad hoc IPv6/IPv4 measurements.

RIPE NCC and Duke University BGP Experiment
Erik Romijn — Aug 31, 2010 02:40 PM

On 27 August 2010, the RIPE NCC's Routing Information Service (RIS) was involved in an experiment using optional attributes in the Border Gateway Protocol (BGP). As a result of this experiment, a small, but significant percentage of global Internet traffic was disrupted for a period of about 30 minutes. The following article provides some background information on the experiment itself and its effect on the network.

Following the first announcement of the active measurement network we are planning to set up, you can find a short description below of the equipment we are planning to use for all vantage points.

Interesting Graph - IPv6 Performance
Emile Aben — Aug 25, 2010 01:00 AM

This graph shows IPv6 performance as measured to These measurements show performance of native IPv6 on average being very close to IPv4.

Refinements to the RIPE Database Query API
Paul Palse — Aug 23, 2010 09:00 AM

Over the last few months, since the last release of our RESTful Query Web Service, we have been adding functionality and fixed some issues that we found while using the underlying API. So, with this update we are releasing all these refinements and fixes to you. Most of the improvements address parsing complexities of the RPSL format.

RIPE NCC Validator for Resource Certification
Amanda Gowland — Aug 20, 2010 10:10 AM

Resource certification can be used to help secure routing. The resource certification system is based on Public Key Infrastructure (PKI) principles. The RIPE NCC Validator for resource certification can help network operators make the necessary routing decisions. You can download the tool below.

IPv6 RIPEness - Criteria for a Potential Fifth Star Rating
Vesna Manojlovic — Aug 17, 2010 02:50 PM

We recently posted an article about IPv6 "RIPEness", a four-star rating system of Local Internet Registry (LIR) IPv6 deployment.

Active Measurements Need More Vantage Points
Daniel Karrenberg — Aug 16, 2010 09:30 AM

This is the first in a series of articles in which we will describe our plan to set up a new measurement network and how we plan to master the engineering, economic and community-building challenges.
