Location: Amsterdam, NL

I'm a system architect 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 visualization and security. When I'm not working I like to play electric guitar and run in circles, while listening to music.

Distribution of RIPE Atlas Probes

Emile Aben — Dec 16, 2014 01:55 PM

Distribution of RIPE Atlas Probes As the RIPE Atlas network continues to grow, it's useful for ambassadors and potential probes hosts to easily see where we already have probes deployed and where we'd like more probes installed. We created a few useful maps to help with this.

Propagation of Longer-than-/24 IPv4 Prefixes

Emile Aben — Oct 02, 2014 05:10 PM

Under ARIN's Number Resource Policy Manual (NRPM) Section 4.10, the IPv4 address block 23.128/10 is reserved for allocations and assignments dedicated to facilitate IPv6 deployment. The maximum allocation size is a /24; the minimum allocation size is a /28. There has been much discussion on the NANOG mailing list about the usability/routability of prefixes longer than a /24. In order to try to provide some additional data on this topic, the RIPE NCC has requested a small block of address space from the reserved /10 to test these types of prefixes.
