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 Shape of a BGP Update
The Shape of a BGP Update
Vasco Asturiano — Feb 14, 2011 04:00 PM

What happens to BGP traffic when an announcement or withdrawal of an address prefix propagates through the Internet? See below some interesting graphs and observations.

Kaveh Ranjbar — Feb 14, 2011 01:35 PM

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.

RIPE Database REST API Documentation
Benedetto Fiorelli — Feb 11, 2011 02:05 PM

The RIPE Database RESTful Web Services API are REST interfaces to the Whois Database. The latest version of the API offers full CRUD support and also new advanced methods to programmatically manipulate RIPE Database objects. Find here some documentation.

New RIPE NCC Address Statistics Reports
Mirjam Kühne — Feb 08, 2011 10:50 AM

How do we know which addresses are still unallocated or unassigned? Find below a proposal to include unallocated address space in the statistics files the Regional Internet Registries publish daily.

Visualizing the Egyptian Disconnection
Richard Barnes — Jan 30, 2011 07:40 PM

In the routing graphs produced by the RIPE REX tool, we can get a different visualization of Egyptian networks falling off of the Internet, and observe some interesting phenomena.

Interesting Graph - Global Patterns in IPv4 Allocation Statistics
Rene Wilhelm — Jan 28, 2011 05:30 PM

With IPv4 depletion imminent, we're keeping a close eye on allocation rates. In the article below you can see the IPv4 address allocations rates over time in all regions.
