Microsoft has offered to pay $7.5m (£4.7m) for net addresses from bankrupt telecoms firm Nortel.
The 666,624 IP version 4 (IPv4) net addresses were put up for auction as part of the sell-off of Nortel's assets.
Blocks of IPv4 are valuable because the pool of this generation of address is close to running dry.
