The Cisco Networkers 2009 event is over now, the web site is now static and the statistics will be kept for several months. In order to interpret the MRTG & NetFLow data, here is a chronology:

For the 2nd Time: IPv6 at Cisco Networkers Barcelona in January 2009

IPv6 Hall of Fame
Do you want to win some Belgian chocolate by running IPv6? yes ! no
...checking whether you have IPv6 access even if you used an IPv4 address to display this page...
To see the animated dragon, you need to enabled IPv6 on your laptop.

The IPv6 connectivity is provided by Space Net with spare time of some Cisco IPv6 enthusiasts. A clickable network topology also describes how the connectivity is achieved.
Some traffic statistics: If you want to comment on this initiative, please join us on the Social Networking web site: https://www.cisconetworkers2009.com/eventlink/ in the group IPv6 for the Better or the Worse.

Your address is 38.103.63.60.

User-Agent: CCBot/1.0 (+http://www.commoncrawl.org/bot.html)

How to do the above? with a very simple PHP script :-)
if (strstr($_SERVER['REMOTE_ADDR'],":")) {
        print("<img src=dragonanime.gif>") ;
} else {
        print("<img src=dragon.gif>") ;
}
print("Your address is $_SERVER[REMOTE_ADDR].<br>") ;

Please contact Eric Vyncke if you want more information about this set-up.
