I will note that the draft proposed establishing an IID registry, but AFAICS doesn't specify that these must be excluded from auto-configuration or other such functions. Or is such "exclude IIDs listed in the registry" specification expected to happen in the future, in revised protocol specifications? That was a main open issue I saw in the (short) draft. It would also have been useful if there had been more text to give guidance to the designated expert on in which cases it would be OK to accept a registration. As the draft cites 'exceptional circumstances', maybe a higher bar (e.g., IETF consensus or Standards action) would also be possible. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
