About the author

I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.

RIPE Atlas - Packet Size Matters

This new RIPE Labs article talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmente…

The methodology is what we think to be the best compromise yet between simple and fair. In this first version, 573 LIRs …

Networks With IPv6 Over Time - A Short Update

We regularly check the status of IPv6 deployment in the RIPE NCC service region, but also in other regions. One way to measure IPv6 deployment is to look at the percentage of networks (Autonomous Systems) announcing IPv6 prefixes and to follow the developments over time.

IPv6 RIPEness - More Stars

IPv6 RIPEness helped in creating awareness and got people into action with regards to their first steps towards deploying IPv6 in the RIPE NCC service region. Up until now IPv6 RIPEness didn't measure actual IPv6 deployment. In this article we propose a measure (a "5th star"), which attempts to mea…
