May I ask why this is interesting? Don’t we have a worldwide DNS service IPv6 capable? Why we are trying to reinvent the wheel? Honestly, it sounds to me a bit odd….. even useless without proper objectives…. What I’ve read is a kind-of non-sense as it was written and exposed: The network is no longer a contiguous IP block devoted to Amateur radio —> It’s really important? Honestly? Organizations with real interest can request larger blocks and interconnect themselves. All IPs will encode in their last 64bits the callsign of the Amateur responsible for such station or device. This eliminates all possible ambiguities and difficulties when trying to determine which Amateur is behind a certain IP address. —> Unnecessary at all, insecure by default and a lack of privacy. Whitelists —> Unnecessary. There are multiple options to avoid this ranging from a pure non-filtering, filtering, performing IPv6-to-IPv4 routing or even perform cloud/virtual networking implementations. Honestly, my criticism here is due to the nature of the proposal as it was written, not the benefits for the ham radio community or the technological advances we can take advantage. -- Vy73 de EA1HET, Jonathan
