The IPv6 Pocket Guide is an excellent resource for students of SEC503: Intrusion Detection In-Depth. In addition to information on IPv6 headers and addresses, it includes quick-reference material on commonly used acronyms, tcpdump usage, routing and fragment headers, and more.
This easy-to-reference cheat sheet would also be useful to students of SEC401, SEC573, SEC560, FOR572, and LDR512.
