Four sets of default IP addresses are assigned at manufacturing:
Management IP addresses — IP addresses used by Oracle ILOM for the compute servers, storage servers, and the storage controllers.
Host IP addresses — Host IP addresses used by the compute servers, storage servers, storage controllers, and switches.
IB IP addresses — IB interfaces are the default channel of communication among compute servers, storage servers, and the storage controllers. If you are connecting SuperCluster to another SuperCluster or to an Oracle Exadata or Exalogic machine on the same IB fabric, the IB interface enables communication between the compute servers and storage server heads in one SuperCluster and the other SuperCluster or Oracle Exadata or Exalogic machine.
10GbE IP addresses — The IP addresses used by the 10GbE client access network interfaces.
