I'm confused. The ARIN NPRM says: 6.3.4. Aggregation ... Further, RIRs should apply practices that maximize the potential for subsequent allocations to be made contiguous with past allocations currently held. However, there can be no guarantee of contiguous allocation. and 6.5.7. Existing IPv6 address space holders Organizations that received /35 IPv6 allocations under the previous IPv6 address policy (RIRv6-Policies) are immediately entitled to have their allocation expanded to a /32 address block, without providing justification, so long as they satisfy the criteria in Section 6.5.1.1. The /32 address block will contain the already allocated smaller address block (one or multiple /35 address blocks in many cases) that was already reserved by the RIR for a subsequent allocation to the organization. Requests for additional space beyond the minimum /32 size will be evaluated as discussed elsewhere in the document. That's the sort of reserve for future allocation I was talking about. These quotes are from the IPv6 portion of the manual, but I thought from many references in conversation, email, etc. to space reserved for expansion that this occurred in IPv4 as well. --Sandy _______________________________________________ Sidr mailing list [email protected] https://www1.ietf.org/mailman/listinfo/sidr
