According to the Internet Governance Project site, “The March 23 edition of the Dow Jones Daily Bankruptcy Report has reported that Nortel’s block of 666,624 IPv4’s was sold for $7.5 million – a price of $11.25 per IP address. The buyer of the addresses was Microsoft.”
I have been wondering if this was going to start happening. It definitely seems a logical response to the depletion problem. I don’t think the Regional Internet Registries have considered IP addresses as an asset to be bought, sold, or brokered.
