Not much to see here, eh? This is mostly just the landing page for some of the domains I own.

I'm currently working as Security Officer and Manager Datacenters, Networking and Research & Development for BIT, a business to business ISP in the Netherlands.

You can find me on Linkedin, follow me on twitter or check out my photos.

Things that interest me are:

• networking: routing, switching, IPv6, BGP, MPLS, loadbalancing, etc
• security: DNSSEC, running honeypots, social engineering
• coding: tinkering with Python, Perl, PHP and bash
• reading: my favorite authors are Robert Jordan, Terry Pratchett, Frank Herbert and Terry Goodkind
• photography: I love taking pictures of animals and landscapes, check out some of my photos
• volleyball: not playing in a competition at the moment, but still enjoying playing with some friends
• biking: I enjoy riding my ATB in the Dutch polders
