Comparing Certified Resources to BGP Routing
Comparing Certified Resources to BGP Routing
Alex Band — Aug 23, 2011 03:25 PM

We have implemented a new feature in the Resource Certification Service that compares the certified resources a Local Internet Registry (LIR) holds and the Route Origin Authorisations (ROAs) they have created with the BGP announcements seen by the RIPE NCC Remote Route Collectors. It will display the validation results, and can notify the user of mismatches and potential hijacking attempts.

Local Certification Service Launched
Local Certification Service Launched

In order to use the RIPE NCC Resource Certification (RPKI) Service, the only option up to now was to rely on the hosted system in the LIR Portal. Today we are releasing a proof of concept of the Local Certification Service. This allows RIPE NCC members to run Resource Certification on their own systems.

Prompted by a discussion at the last RIPE Meeting, we found out how many maintainer (MNTNER) objects are registered in the RIPE Database and what type of authentication methods are used to secure the data covered by these MNTNER objects.

Measuring World IPv6 Day - Comparing IPv4 and IPv6 Performance
Emile Aben — Aug 01, 2011 11:50 AM

During World IPv6 day we measured the performance of IPv4 and IPv6 between 40 vantage points and 46 World IPv6 Day participants and other dual-stacked sites. If one has to pick a winner, then the old protocol, IPv4, would win, but IPv6 often shows comparable or better performance.

The RIPE NCC has been assigning 32-bit Autonomous System Numbers for quite some time now. In this article we're showing a number of statistics and some analysis.

RIPE NCC Active Measurements Of World IPv6 Day Dataset
Emile Aben — Jul 18, 2011 10:25 AM

As part of our Data Repository we released a new dataset. This dataset contains DNS lookups (A+AAAA), ping/ping6, traceroute/traceroute6 and HTTP fetches (IPv4/IPv6) from 40 vantage points (TTM, CAIDA Ark, and others), to 53 web sites involved in World IPv6 Day. The data covers the period from 2011-06-01T00:00 to 2011-06-13T00:00 UTC.

Emile Aben — Jul 05, 2011 04:05 PM

In this article we'll look at some of the more long-term effects of World IPv6 Day, as seen in our measurements a number of weeks after the event itself.

We experience an increased query load on K-root, the root server operated by the RIPE NCC. See below some analysis and graphs showing the traffic on K-root and other root servers.
