BTW in case it is a non-event, you can post fun IPv6 addresses that you notice.

Here's some. Check the AAAA for:

www.facebook.com www.luns.net.uk www.cisco.com

EDIT:

I meant, check the literal IPv6 addresses that correspond to these hostnames. I'll put emphasis so it is more visible :)

2620:0:1c08:4000:===face:b00c===:0:1, 2a01:8900:0:1::===b00b:1e5===, 2001:420:80:1:===c:15c0:d06:f00d===

EDIT2:

And while you're at it - maybe enable AAAA record for your site and give it a whirl! (and come up with some more creative IPv6 addresses in the process!) Thanks to guylhem for reminding about this.
