But my understanding is that ARIN has no authority over transfers from a truly "legacy" (i.e., non-contracted) holder. If such a legacy holder wants to transfer to RIPE region without ARIN needs assessment, they can if RIPE allows it. ARIN will fuss and bluster about it, but so what? Milton - Your understanding is incorrect. ARIN operates the registry in accordance with the policy developed by ARIN region, and resources in the registry are therefore completely subject to those policies. As I noted earlier, we'd prefer contracts where possible, but even a party that does not have a formal contract can chose to participate or not. You can use any numbers you want in your routers, but if you wish to use numbers which are unique per the Internet Registry system, then you are participating in the Internet Registry system, gaining the benefits thereof, and therefore are subject to the policies used in its coordination & operation. Feel free to read <https://www.arin.net/resources/legacy/>, question #18 and related answer for more background. Thanks! /John John Curran President and CEO ARIN
