I have updated the graph to include 6rd, based on my understanding that the prefixes of the form 2a01:e3xx: are your 6rd space. There is *other* FreeNet space, which appears to do things, but I sense its not part of the 6rd deployment since the numberforms in the lower /64 appear to be infrastructure assignment, not classic customer space forms. Please let me know if I have this wrong. You will notice that this count places Free/6rd at a far lower relative % of unique DNS than the measures of traffic and sources people discussing here. I think this bears thinking about. http://labs.apnic.net/dns-measurement/ -George _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
