ip addresses for sale

Microsoft is trying to buy ~650k IPv4 addresses from in-bankruptcy-proceedings Nortel (for $7.5m).

What gets me is that IPv6 has been a standard for over a decade, and yet so few have moved to it. Way back when I was in college the first time – in 2000 – our networking professor told us we should move to IPv6 as soon as feasible. Somehow I don’t think 11 years meets that urging.
