6.9 Anycasting TLD and Tier 0/1 ENUM Nameservers
Critical DNS infrastructure is defined as infrastructure providing Authoritative TLD or ENUM Tier 0/1 DNS lookup services.
The term "Critical DNS infrastructure" is defined here just to be referred to in one single place three paragraphs down. I'd prefer if the term would be avoided and "Authoritative TLD or ENUM Tier 0/1 DNS lookup services" be inserted at the appropriate place.
We could probably change this, but I think that the reasoning behind this definition was not only to use it as reference, but also to say that these DNS servers are different - all other domain names depend on them.
The organisations applicable under this policy are TLD operators as defined by IANA and ENUM operators as defined by the ITU. The organisation may receive up to four /24 prefixes per TLD/ENUM. These prefixes must be used for the sole
"TLD operators as defined by IANA" may be a well intended phrase, but many affected registries would reject being "defined" by IANA. This layer 9 stuff aside, I'm still uncertain whether the assignment goes to the registry itself or to some operator who provides name service for TLDs (or ENUM, for that matter). The former makes more sense to me. "TLD manager/administrator as described in RFC 1591" might be more acceptable.
I did some reading on IANA website and maybe the problem is that each of us imagine different thing under "defined by IANA" since I didn't find anything like this on IANA website. Since RFC 1591 and ICP-1 uses term 'designated manager' and other IANA documents speaks about "(re)delegation" would: "designated manager for TLD as delegated by IANA" be OK
Similar considerations apply to "ENUM operators as defined by the ITU". As a side note, ENUM Tier 0 assignments would probably have interactions with the policy proposal on "Assignments to the NCC".
ITU documents use these terms: 3.2.1 administrator: The organization entrusted with the administration of a resource derived from an international numbering plan. 3.2.2 assignee: The applicant to whom E-series international numbering resources have been assigned. 3.2.3 assignment: The process for providing an international numbering resource to an eligible applicant. 3.2.4 country: A specific country, a group of countries in an integrated numbering plan or a specific geographical area. so is "ENUM administrator as assigned by the ITU" more appropriate?
