I think it should say:

I don't think it should say this either Antoin. :-( The NCC does not define the ENUM operators: its role in ENUM is strictly neutral. Strictly speaking, IAB chose the NCC as the ENUM Tier-0 registry and the National Administrations select their corresponding Tier-1 registry. I suggest the following language/definition: Critical Infrastructure Domain: a TLD listed in the IANA database (insert URL here), e164.arpa or any delegation of e164.arpa made according to the arrangements in place between RIPE NCC, IAB and ITU-T (insert url here). Then in the modified 6.9 for RIPE424 say something like The organisation(s) applicable under this policy are operators of Critical Infrastructure Domains. I'm uneasy about explicitly listing e164.arpa since this means the NCC would in principle be able to allocate resources to itself. This might not be wise. Another concern here is ICANN's plans for lots of new TLDs. Though I expect we'll be out of IPv4 space before those TLDs come on-line. And here's a wider question: do these allocations of /24s for infrastructure anycasting go to the registry operator or should they be linked to the domain name? ie If the registry for .nl or 1.3.e163.arpa moves from SIDN, do any anycast allocations for these domains stay with SIDN or would they go back to the NCC or get transferred to the new registry operator?
