To help explain IPv6, Leo Vegoda has penned a piece for the ICANN Blog saying "there are a lot of addresses and lots of new things to learn if you are only familiar with an IPv4 environment. But as we implement IPv6 across our networks we will see IPv6 addresses popping up in mail headers, system logs, traceroutes and all sorts of other places where IPv4 used to be used exclusively. Knowing quickly whether an address is part of your own network or someone else's; whether an address is intended for private use or Internet use; and knowing whether an address is used by a transition mechanism or a native connection will help save lots of time."
As part of the piece, Vegoda notes that "last year, ICANN staff worked with the staff at APNIC and the RIPE NCC to produce a single sheet that identified the key address groups, explained what they were and gave IPv4 examples of IPv4 equivalents where they existed. This year we have updated the sheet and you can grab a copy of the updated reference from here." Todayisp.com has uploaded it as follows:
