* Unless otherwise configured, OVN-Kubernetes uses the following IP address ranges:
** `100.64.0.0/16`. This IP address range is used for the `internalJoinSubnet` parameter of OVN-Kubernetes by default. If this IP address range is already in use, enter the following command to update it to `100.63.0.0/16`:
* OVN-Kubernetes reserves the `100.64.0.0/16` and `100.88.0.0/16` IP address ranges. If OpenShift SDN has been configured to use either of these IP address ranges, you must patch them to use a different IP address range before starting the limited live migration.
