Why couldn’t the transactions all be completed before the first one is filed with an RIR? After all, if you’re willing to circumvent policy to the extent mentioned by David in his other messages, surely it is trivial to make those purchase agreements in such a way that the transaction is finalized well ahead of a coordinated notification to the RIR(s). > Worldwide there have been less than 1500 transfers.

I agree… I don’t think it is the mobile operators who are most likely to be the problem here. Most of them are actually showing pretty strong support for IPv6 (AT&T and SPRINT notwithstanding). Owen
