One way to determine the denseness of the Internet, or its “interconnectedness”, is to look at the path length between Autonomous Systems (ASes). A while ago we looked at that and also at differences between IPv4 and IPv6 networks. Has this changed in the meantime? See our findings below.

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

Andrea Cima

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…

RIPE Atlas - A Case Study of IPv6 /48 Filtering

Emile Aben

• 26 Jul 2012

• 9 min read

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…
