You can review the network configuration and control the network address type using the srvctl config network (to review the configuration) or srvctl status network (to review the current addresses allocated for dynamic networks), and srvctl modify network -iptype commands, respectively.
You can configure how addresses are acquired using the srvctl modify network -nettype command. Set the value of the -nettype parameter to dhcp or static to control how IPv4 network addresses are acquired. Alternatively, set the value of the -nettype parameter to autoconfig or static to control how IPv6 addresses are generated.
The -nettype and -iptype parameters are not directly related but you can use -nettype dhcp with -iptype ipv4 and -nettype autoconfig with -iptype ipv6.
Note:
If a network is configured with both IPv4 and IPv6 subnets, then Oracle does not support both subnets having -nettype set to mixed.
Oracle does not support making transitions from IPv4 to IPv6 while -nettype is set to mixed. You must first finish the transition from static to dhcp before you add IPv6 into the subnet.
Similarly, Oracle does not support starting a transition to IPv4 from IPv6 while -nettype is set to mixed. You must first finish the transition from autoconfig to static before you add IPv4 into the subnet.
