You may also know him by his work on RFC6555 (“Happy Eyeballs”), or, the video at https://m.youtube.com/watch?v=v26BAlfWBm8 . He might be blamed for the idea of FOSDEM main WiFi being unapologetically IPv4-less (and for dual-stacking WiFi at some other large events), which resulted in RFC7772.

Network automation for event networks is a 10-year long passion - it gives an opportunity for “just in time coding extreme” in Rust, hands-on work, and great friendships!

He is CCIE#5423 Emeritus in Routing&Switching and Security.

Robin is a Network Architect working with organizations to improve their network operations. This includes not only implementing shiny new and innovative technology, but more importantly also leveling up the team by improving operational processes and increasing skill levels. This means showing rather than telling the right way forward, and also talking about all the mistakes he made to help others avoid those.

When he’s not behind a computer, you might find Robin riding his bicycle through the Veluwe forests, or engaged in mock sword fights.

Next to being dad, geek and entrepreneur Rudi tries to help (re)structuring the network at the Air Traffic Control center (LVNL) at Schiphol airport (NL) as an Network Engineer. Being educated in Electronics Design Enginering, Rudi has worked in all layers of the stack from the chip level to (almost) the political level, but his interests mainly focus on the lower part. Rudi has more than 35 years of experience in the UNIX and open standards world, ranging from systems in large (data-centers) environments to the small (embedded and chip) world, and their interconnects.

Rudi is an active member of NLUUG, USENIX and IEEE and likes to organize and visit their conferences. In his spare time, he’s into landscape photography, sailing and HAM Radio, traveling, and tries hard to combine this. Currently Rudi serves as chairman of the NLUUG board of directors.
