I totally disagree. This was a liquidation at a bankruptcy court, and Microsoft likely bought it only because they could. It's very difficult to transfer IPv4 space... the massive routing tables won't allow a lot more partial transfers. So if anything, the RIRs will step in soon and say "transfers not allowed", just to preserve the routing table size. I suppose you could *tunnel* a partial space, but that'd be like getting hand-me-downs... IPv4 traffic that has to be tunneled to get to where it really needs to go. If you need a better explanation, consider this. Suppose I own 4.x.x.x right now (that's 4.0.0.0/8), and I'm really only using half. So I decide to sell you 4.N.x.x where N > 127. Now, if you're not immediately adjacent to me on the internets (and it's not possible to be adjacent on multiple vectors, so the answer is *never*), every single ASN router will have to record *two* routes where they formerly had one: one toward me for 4.0.0.0/9, and one towards you at 4.128.0.0/9. If people are allowed to do that, the routers would quickly collapse. The RIRs won't allow that. Thus, there's not going to be an IPv4 gold rush, and instead IPv6 *must* be deployed before the first RIRs are dry. -- Randal L.
