Ensuring Registry Data Quality
Ensuring Registry Data Quality
Xavier Le Bris — Mar 08, 2011 12:25 PM

In order to ensure accurate and up to date registration data, the RIPE NCC started the Registry Data Quality project in 2009. The article below describes this activity and the problems we found and how we fixed them.

Network Complexity and How to Deal with it
Network Complexity and How to Deal with it
Michael Behringer — Mar 01, 2011 11:10 AM

This article, prompted by a panel discussion at the RIPE 61 Meeting, describes the most significant implications of network complexity and suggests ways to deal with it. This is a topic that requires more work and a lot of input from network operators. We hope you’ll work with us to advance this subject.

First Impressions of Pollution in Two RIPE NCC Darknets
First Impressions of Pollution in Two RIPE NCC Darknets
Manish Karir — Feb 21, 2011 09:40 AM

We partnered with several Regional Internet Registries (RIRs), including the RIPE NCC, to examine what traffic is going to unallocated IP address ranges. In this particular case, we looked at traffic going to 5/8 and 37/8.

Members and Number Resources, One Year Later
Rene Wilhelm — Feb 17, 2011 04:20 PM

Last year, in a series of two articles, we presented statistics on the number of RIPE NCC members and the resources distributed to our members. With twelve months passed, we revisit the topic and look at how things evolved in 2010.

Create, Update and Delete via the RESTful Web Services
Paul Palse — Feb 15, 2011 02:50 PM

When we started developing the RIPE Database API and the accompanying RESTful web services, we first implemented the "Read" service. The RESTful web services now also support Create, Update and Delete functionalities. Not only did we implement these methods, but we also introduced some workflow refinements that should make programmatic interaction with the RIPE Database much easier, taking away some of the common aches of the way the legacy "Mail" and "Sync" update interfaces work.

Three Case Studies on the Egyptian Disconnection
Claudio Squarcella — Feb 15, 2011 09:30 AM

Roma Tre University presents three analyses related to the recent events in Egypt, proving interesting behavior in relation to the observed disconnection. We use tools like BGPlay and iBGPlay, developed for the visualisation of BGP dynamics.

The LIR Locator tool has been updated. It now contains a number of new options and features, including information about Local Internet Registries (LIR) with 4-star IPv6 RIPEness. The tool is mostly targeted to the members of the RIPE NCC, but also contains a public map accessible to everyone.
