The examples raised on-list, in my understanding, referred to the following: -- The possibility of two adjacent allocations from the same source being issued at different times with different validity periods and the single issuer being unwilling to issue an aggregate cert (Dr. Kent, 7/31/07) For this example (and ignoring the unwilling-to-issue part) ARIN has never, and will likely never, issue adjacent allocations at different times, ***with different validity periods*** (end point validity, that is). All reserves allocations of adjacent space conform to the validity period of the address block being extended. (FWIW, ARIN would not issue 'experimental' space that is contiguous/aggregatable with 'normal' space either, and has never been asked to nor done so.) -- The possibility of two (or more) adjacent allocations, received by the same entity, coming from two (or more) different sources. For this example, ARIN has never issued resources to two (or more) different organizations who, by happenstance or purpose, have registered further adjacent, aggregatable downstream reallocations to a single third-party entity. To be clear, I understood from the thread that the issues centered on differing-validity-periods-while-adjacent (not happening at ARIN) and split-parent-while-adjacent (in my opinion rare, and not seen at ARIN from our observations).
