Oracle EXADATA X6-2 Installation And Configuration Manual page 278

When a server is shipped from the factory, the elastic configuration code is executed
when the server is first powered on. At that time, the machine will be assigned an IP
address in the 172 range.
To prepare a new Exadata system for deployment using the elastic configuration
method, perform the following steps:
Obtain the latest Oracle Exadata Deployment Assistant (OEDA).
1.
Run the OEDA configuration tool to generate the configuration files.
2.
Power on all the servers.
3.
Database nodes and cells will automatically assign to themselves unused IP
a.
addresses on eth0 in the 172.16 range.
Host names of the nodes will be of the format "nodeN", where N is a number.
b.
If you are using Oracle VM, run
4.
database servers will reboot. If you are using physical deployment and not
virtualized deployment, then you can skip this step.
For example:
