Microsoft buys 666,624 IPv4 addresses from Nortel for $7.5 million
Microsoft ponied up $7.5 million for the Nortel pool, which works out to just over $11 per IP address. There were reportedly 13 other interested buyers, but only Microsoft and three others actually submitted bids.
With the last block of IPv4 addresses already issued, snatching up 2/3 of a million in one fell swoop is a smart move by Microsoft, and we're sure they have plans for the IPs. As far as what those plans actually are, we'll just have to wait and see -- though something cloud-based seems like a safe bet.
