Hello Scott-

As you indicate above, NRPM 6.5.1.1(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.
