RIPE NCC Registration Services "Dry Run" For Last /10 Procedures

RIPE NCC Registration Services "Dry Run" For Last /10 Procedures

2 min read

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"…

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 p…

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 re…

An alternative way of looking at the prefix size distribution in IPv4 and IPv6 blocks is now available in RIPEstat as an interactive widget. Tabular visualisation and cumulative percentage representation can be used for filtering based on minimum allocation size or for general research about the us…

We've enabled RIPE NCC members to do IPv6-traceroutes from all RIPE Atlas probes to IPv6 destinations. Until now they could get the raw analysis results (text/JSON representations of traceroute results) for analysis. In this article we present a first experimental analysis and visualisation of the …
