The Training team has been working on an exercise for the IPv6 training course we deliver for LIRs. It's aimed at people who are unfamiliar with IPv6, so the goal is to get them to the point where once they get their IPv6 /32 allocation, they have a good idea how to subdivide prefixes over their network and how to write an addressing plan. Here's a PDF with the exercise (two pages A3): http://bit.ly/c7jZRJ We are curious to hear if you think it's clear and useful. Any feedback is greatly appreciated. Thanks, Nathalie Trenaman RIPE NCC Trainer (Big props go to Marco Hogewoning @XS4ALL)
