As you indicate above, NRPM 22.214.171.124(3) states that an organization "must
plan to provide IPv6 connectivity to organizations to which it will
assign IPv6 address space, by advertising that connectivity through its
single aggregated address allocation".
If a requester answers YES to question 14, then this clearly meets the
policy. A NO answer to this question would not be an immediate denial,
but instead would lead staff to ask for clarification as to whether the
organization intended to announce the single, aggregated prefix at all.
The policy doesn't specifically preclude an organization from announcing
more specifics of the larger prefix.
Because this question seems to be somewhat confusing, ARIN staff will
update the template today to clarify this question and the instructions.
