To enable IPv6 support, perform the following steps:

Specify your internal registry’s Portworx operator image path in your Portworx operator spec. Replace the line image: portworx/px-operator:<version_number> in the generated Portworx operator spec with the path to your internal registry operator image. For example:
```
image: <image_registry_hostname>/<repo_name>/<image_name>:<tag>
```
If your internal registry is password protected, create a secret to store the credentials, then specify the internal registry access info in the Portworx Storage Cluster spec. For example:
```
imagePullSecret: <secret_name>
customImageRegistry: <image_registry_hostname>/<repo_name>
```

Specify the oci-monitor path in the internal registry. For example:

spec:
  image: <image_registry_hostname>/<repo_name>/<image_name>:<tag>

For dual network deployments, specify network configuration. For example:

  network:
    dataInterface: <interface_name_for_data_traffic>
    mgmtInterface: <interface_name_for_mgmt_traffic>
