Florian Obser (florian@) recently gave a BSD-NL talk entitled "Let's find out how to get predictable IPv6 addresses assigned to OpenBSD VMs".
Florian takes us on a guided tour of how inet6 autoconf actually works, with enlightening and entertaining peeks into selected piece of OpenBSD source.
At the end, we are asked to "now, draw the rest of the owl".
