Hello!
Hurricane Electric is happy to announce that we've released an IPv6 Certification Program. This will provide you with something entertaining to do after you have established IPv6 connectivity, as well as a way to test your IPv6 readiness and your ability to host services available on IPv6.
http://ipv6.he.net/certificationTunnelbroker.net users are already enrolled in the program, and should use their username/password for Tunnelbroker.net to log in. (enable javascript)
For any questions about the program, or issues you might have, please email
ipv6@he.net
