Default InfiniBand bonded IP addresses are assigned to Exalogic compute nodes at the time of manufacturing. However, you can reconfigure the IP addresses by using the Oracle Exalogic Configuration Utility. The Oracle Exalogic Configuration Utility and its associated scripts reconfigure InfiniBand Bonded IP addresses based on the input you provide to the Exalogic Configurator spreadsheet.
For a list of default InfiniBand Bonded IP addresses, see Default IP Addresses and Ports.
