Anycasting Assignments for TLDs and Tier 0/1 ENUM

I support the proposal, but I'm still unhappy with parts of the wording: {only looking at the v4 text, comments apply to the v6 version accordingly}
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.
I'm happy to change this if the working group feels it's needed.
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.
Well the input from the working group I had received earlier was that the allocation should not necessarily go to either the registry or the DNS operator but to the organisation who has been delegated authority over the namespace from either IANA or ITU, In most cases this is the same organisation but it could be that the IANA/ITU gives responsibility for a Tier1 ENUM to an organisation[1] and they subcontract the registry to one company[2] and public facing DNS to another [3], in this situation my intention was for the allocation to go to [1] I believe the wording as is reflects this, I'm happy to update it but would prefer the allocation still goes to [1] How about "The organisations applicable under this policy are TLD operators as recorded in the IANA's Root Zone Database and ENUM operators as approved and recorded by the ITU".
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".
purpose of anycasting authoritative DNS servers for the stated TLD/ENUM, as described in RFC 3258.
This is a verbatim quote from the current policy documents, but a reference to BCP126/RFC4786 might be more appropriate these days.
This sounds sensible
Assignments for Critical DNS infrastructure are subject to the policies described in the RIPE document entitled "Contractual Requirements for Provider Independent Resource Holders in the RIPE NCC Service Region".
Anycasting assignments are registered with a status of 'ASSIGNED ANYCAST' in the RIPE Database and must be returned to the RIPE NCC if not in use for Critical DNS infrastructure any longer.
OK, 2nd occurence, but s/Critical DNS infrastructure/the purpose justifying the assignment/.
Thanks for the comments, Some credit should also go to Leo Vegoda for some input, thanks Leo. Brett
