IPv4アドレスはまだまだ大丈夫ですよという話

Geoff Huston's excellent July 2003 paper, "IPv4 - How Long Have We Got?". [...] to predict future growth in demand, Geoff uses statistically reasonable projections to argue convincingly that the IPv4 space will likely last until around 2022. In any event, there is no evidence that IPv4 addresses will be exhausted in the coming decade.

In short, the "Death of the Internet" due to lack of IP space is a myth, which doesn't bode well for getting IPv6 rolled out any time soon."

G3ワイアレスの時代になると，一つのデバイスに一つのアドレスを割り振らないとならないので，IPv6が必要になるらしい。
