As far as I can tell, the assumptions behind this policy proposal includes the assumption that a top level authoritative name server will need to use IPv4 for the foreseeable future, so that an explicit reserved pool of these IPv4 addresses needs to be maintained for use by the authoritative name servers for these domain names.… Read more
