IPv6-enabled content!
I'm very excited. This morning I found my first IPv6-enabled web site with content for a general audience: www.crooksandliars.com.
All of the IPv6-enabled web sites I've seen so far are oriented at geeks. While some of us may like to see dancing turtles, peruse lists of IPv6-enabled applications, download free operating systems, or even read internet standards, most normal users won't find these activities too interesting. While I'm not necessarily endorsing crooksandliars.com's content, it is aimed at a general audience. So I'm very happy that it's IPv6-accessible.
In an earlier blog entry, I mentioned the ShowIP extension for FireFox. This tool displays the IP address of the site you're visiting in FireFox's toolbar. If it's green, you're using IPv6. This morning, while reading digg, I followed a link to crooksandliars.com and noticed my toolbar go green:
As an added bonus, not only is www.crooksandliars.com accessible over IPv6, but so are its authoritative nameservers:

Sadly, the IPv6 internet's routing system is still less developed that the IPv4 internet's. Pings to www.crooksandliars.com from my desktop over IPv6 take about 3x longer than over IPv4 (252 ms compared to 83 ms, respectively).

Unfortunately it seems that ShowIP shows (preferentially) any IPv6 associated with that name and not the real address that was used for the actual connection: on kame.net I see the IPv6 address, though the turtle doesn't dance (for some reason I didn't fathom yet my Firefox/win32 uses IPv4 connections even for hosts that have an IPv6 address even thought IPv6-only ones work flawlessly).
I've verified using WireShark that I'm using IPv6 to connect.
