• 4 min read

The RIPE Routing Information Service (RIS) and RIPE Atlas produce large amounts of data that needs to be processed, stored and made available to the public. We've been using Hadoop for some time now.

Lost Stars - Why Operators Switch off IPv6

One of the measurements that we have been running for a long time is IPv6 RIPEness, where we measure the IPv6 activity of our members. We award our members with stars if they (for example) announce their IPv6 allocation in the global routing table.

Does the Internet Route Around Damage? A Case Study Using RIPE Atlas

Emile Aben

• 11 min read

The Internet has a robust infrastructure that was designed to route around damage. But how well does it do this? We use RIPE Atlas to look at how large-scale disruptions in the Internet's core infrastructure affect end-to-end connectivity on the Internet.

Impact of K-root Expansion as Seen by RIPE Atlas

Rene Wilhelm

• 16 Nov 2015

• 12 min read

In the course of 2015 we have expanded the K-root anycast cluster with 17 hosted servers in 15 new cities. We look at RIPE Atlas to see what impact this had on performance on both global and regional scales.

Rolling over the algorithm (usually to a stronger variant) used to sign a DNS zone isn't as easy as regular key roll-overs. This is because some DNSSEC validators are less forgiving than others, and fail validation unless the right combination of keys and signatures is present in a zone. This ar…

Researching F-root Anycast Placement Using RIPE Atlas

Ray Bellis

• 14 Oct 2015

• 5 min read

In order to expand the reach of F-root, one of the 13 root servers, we at ISC looked at where queries to our F-root servers are coming from and where it would make most sense to place new nodes. As a first step, we looked at the existing nodes to see how they behave and if there is anything we can …
