I was wondering if anyone knows of some good web links, books, articles, or other kinds of sources relating to IPv6?

Reason I ask is that I'm working on a group paper and all of the info that we've found either contradicts some other source, is unclear to the point of not being able to understand what was discussed, or doesn't go into a whole lot of detail. On top of the paper, we also have to present our topic t the class and we'd all like to have a bit more understanding that what we currently have, which isn't much more than the basics.

If anyone knows of any sources relating to general IPv6 overview stuff, security in IPv6, autoconfiguration, or how the transition from v4 to v6 might go, please let me know. Any help will be greatly appreciated.
