Emile Aben

Location: Amsterdam, NL

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.

When Does World IPv6 Day Start?

This will make content available over IPv6 for one full day. Since DNS responses are often cached, some users won't see this change immediately. In this article we look at how DNS caching affects the start of World IPv6 Day, and how World IPv6 Day participants can minimise these effects.… Read more

World IPv6 Day - IPv6 Eye Chart
World IPv6 Day - IPv6 Eye Chart
Emile Aben — 27 May 2011

The RIPE NCC is doing some measurements for World IPv6 Day. One of them is the IPv6 eye chart, a web page that allows you to test your connectivity to selected dual-stacked web sites and World IPv6 participants. The goal is to see if an end user has connectivity problems to dual-stacked websites. This is an increasingly rare problem, but still perceived important enough to prohibit content providers to go dual-stack.… Read more

Unsolicited Internet Traffic from Libya
Unsolicited Internet Traffic from Libya
Emile Aben — 23 Mar 2011

Amidst the recent political unrest in the Middle East, researchers have observed significant changes in Internet traffic and connectivity. In this article we tap into a previously unused source of data: unsolicited Internet traffic arriving from Libya. The traffic data we captured shows distinct changes in unsolicited traffic patterns since 17 February 2011.… Read more
