RIPE NCC Registration Services "Dry Run" For Last /10 Procedures
RIPE NCC Registration Services "Dry Run" For Last /10 Procedures
Andrea Cima — 23 Aug 2012

The RIPE NCC will shortly reach a point where we have approximately one month's worth of IPv4 address space (approximately /10) to distribute before we reach the last /8. Once we reach this point, several adjustments will be made to our standard procedures, so the RIPE NCC decided to do a "dry run" to ensure that the process we designed works properly and provide an opportunity to iron out any flaws.… Read more

RIPE NCC Active Measurements of World IPv6 Launch Dataset
Bert Wijnen — 27 Jul 2012

As part of our Data Repository, the RIPE NCC has released a new dataset. This dataset contains DNS lookups (A+AAAA), ping/ping6, traceroute/traceroute6 and HTTP fetches (IPv4/IPv6) from 53 vantage points (TTM, CAIDA Ark and others) to 60 websites involved in World IPv6 Launch. The data covers the period from 2012-05-19T00:00 to 2012-06-18T00:00 (UTC). … Read more

RIPE Atlas - A Case Study of IPv6 /48 Filtering
Emile Aben — 26 Jul 2012

In this article I look at four different IPv6 destinations in different BGP set-ups and how these are seen by RIPE Atlas probes. This reveals some differences in reachability for the different networks, likely due to BGP route filtering. We see roughly 1% out of ~500 RIPE Atlas probes that can't reach a destination in an IPv6 /48 prefix (without a covering shorter prefix) out of IPv6 PA space, likely due to filtering.… Read more
