Since there's been so much discussion here of IPv6 here, I thought
I'd mention a recent post on CircleID.com called "Examining Actual
State of IPv6 Deployment":
http://www.circleid.com/posts/81166_actual_state_ipv6_deployment/
The article is by Thomas Kuehne and is a "quick-and-dirty" study he
did of how many web sites were configured with AAAA records.
Obviously it's not a comprehensive study, but just another data point
about the readiness for IPv6 - or not. I've included the intro to
the data below.
Enjoy,
Dan

There have been quite a number of recent articles about various IPv6
issues. Thus the question: how far along is the actual IPv6
deployment? This is a quick-and-dirty survey that focuses mainly on
the content provider side.
What domains were surveyed?
Alexa offers country depended TopSites listings. Domains listed are
frequently visited by users from that country, not necessarily hosted
there. The data collection is heavily biased towards sites that host
files referenced from many different places (e.g. advertisement and
social networks). The data collection is chiefly based on optional
browser plugins and is as such frequently corrupted (e.g. for Germany
mail.ru is listed ahead of rtl.de, msn.de and aol.de).
How was IPv6 deployment surveyed?
For each domain the domain name server was asked for IPv4(A) and IPv6
(AAAA) records for the domain, www.domain, it’s mail exchanges and
it’s name servers. If an IPv6 record was returned deployment was
assumed. There was no check if the advised IPv6 actually provided the
service.
