New cheat sheet on IPv6 uploaded today. Preparing this sheet helped me become much more comfortable with IPv6, both as a protocol and as an addressing concept. The information was sourced from a number of texts, including the Cisco Press CCNP BSCI exam guide, Routing TCP/IP vol 1, 2nd ed, and a number of RFCs.

It's odd that, despite having been around for more than a decade, IPv6 has undergone a number of alterations from its original specification. Probably the most obvious example is that of site-local address space (FEC0::/10), which has recently (2004) been deprecated in favor of unique local addresses (FC00::/7). There have also been many IPv4-to-IPv6 adaptation mechanisms proposed, with varying levels of popularity.

If you haven't begun yet, I heavily suggest studying up on IPv6. It's a very intriguing protocol; its larger address space is probably the least interesting benefit offered. It's also on its way to your network.
