Dear colleagues, I am currently handling an end-user request for, initially, a /47 PI (now, due to the NCC stating that a /47 is, generally, not possible, even if routing reasons exist, a /48). During that discussion the NCC shared further details concerning the interpretation of RIPE-738, which I believe may be useful information to share, also in the context of possible ways to improve the address policy for the NCC region. Specifically: - The NCC reads "The minimum size of the assignment is a /48." as the minimum pertaining to the minimal value of the prefix size and not 'the minimum total size of an assignment in the number of IP addresses.' However, it deems it possible that multiple separate /48 can be assigned. => This means that a revision of the IPv6 policy will have to also clarify this point, i.e., by rephrasing it to 'the longest prefix size for an assignment is a /48' - The NCC reads "Assignments larger than a /48 (shorter prefix) or additional assignments exceeding a total of a /48 must be based on address usage or because different routing requirements exist for additional assignments." to mean that larger assignments can only be made based on address usage. Routing requirements can only justify multiple /48. => If this should be clarified, removing the text saying 'for additional assignments.' should suffice. - The NCC reads the reference to Section 5.4.2 in 'The considerations of "5.4.2. Assignments shorter than a /48 to a single End-Site" must be followed if needed.' to imply authoritative language codifying the assignment to a single end-site, and not a reference to a different section requiring the analogous application of the concepts in this section to a PI assignment. => A way to clarify that might be to only reference sections by, e.g., "Section 5.4.2", to ensure that the referenced title of a section is not understood as authoritative language.
