IPv6 is getting the right attraction in the company I work in, and attended a IPv6 training from FastLane (http://www.flane.co.uk/) course_id: (IP6FD) which is not a bad course if you are a beginner coming from an enterprise type of network. Of course, I learnt few new things and in general the topic is quite hot - so, if you are guys are looking for more advanced course, maybe it's worth trying (IPV6SPAM) instead of (IP6FD).
