Sorry to be bringing up a post that’s nearly 5 months old, but it’s the first time that I’ve run across it (I was linked by yesterday’s article from PC Magazine). The IPv6 measurement statistics that you’ve run are great – you might check out http://bgp.he.net/ipv6-progress-report.cgi for some additional interesting figures on global IPv6 deployment.

However, I would like to note that Hurricane Electric Internet Services (AS6939) is far from being simply a “cheap tunnel broker.” Hurricane Electric is a leading Internet backbone and colocation provider that operates the largest IPv6 backbone in the world (as measured by the number of networks connected). NetworkWorld Magazine has a good article on our IPv6 traffic – http://bit.ly/HEipv6nwm.

We are, though, very happy to offer free services like the HE Tunnel Broker, IPv6 certification, DNS management, and BGP toolkit.

Thanks again for the solid post.

Great post. I wouldn’t say IPv6 measurements are lacking though. We did an compilation of IPv6 measurements on RIPE Labs: http://labs.ripe.net/content/ipv6-measurement-compilation , and more recently measured IPv6 on web clients and caching resolvers, presented at RIPE60: http://www.ripe.net/ripe/meetings/ripe-60/presentations/Aben-Measuring_IPv6_at_web_clients_and_caching_resolvers.pdf
