After reading slide 7 I decided to take a closer look at those "funny"
IPv6 addresses. I used host to get AAAA record for the Alexa Top
1Milion domains, and after a lot of DNS lookups I found the following:

70502 GLOBAL-UNICAST
94 IPV4MAP
50 LOOPBACK
49 LINK-LOCAL-UNICAST
30 RESERVED (including 9 RFC 3849 (2001:db8) addresses)
19 IPV4COMP
5 UNSPECIFIED
1 UNIQUE-LOCAL-UNICAST

I planing to modify my script to look for 6to4 and teredo, speed up DNS
lookups and maybe adding www to any Domain without a AAAA record and
runs these test on a monthly base. Any more ideas?

Jens

I am sure that you know about the numerous statistics in a related way on:
https://www.vyncke.org/ipv6status or http://6lab.cisco.com/stats and many
others ;-)

And, if you want to test your extension header (actually only testing the
routing header one): https://www.vyncke.org/sr.php
