First will be the IANA free pool, then each of the 5 RIRs will "runout" at different times, after that there will be many Local Internet Registries (LIRs) that may have space free for a decade or more. In some regions there will be some trading (black/gray/white markets) post exhaustion. > > http://bit.ly/9bzKCP (Enterprise Networking Planet) > > While this article implies that the smallest assigned IPv4 address > block is /22 (1024 addresses) and that assignment of It's actually "allocated", not assigned, but that is just a nit that IP addressing policy folk like me are sticklers about. /24 (256 > addresses) is only being considered for the future, it's worth noting > that many legacy /24 Class C portable blocks have been previously > assigned and are still in regular use. It's also worth noting that many (thousands or tens of thousands of) End User organisations also get /24 assignments currently (not allocations) direct from the RIRs. These are PI (Provider Independent), as opposed to assignments from a LIR to endusers are Provider Aggregatable (PA). We live in interesting times. -- Cheers, McTim "A name indicates what we seek.
