Network Segment Splitting: Suitable for scenarios where network segments need to be refined. After the operation, the public IP status will remain "in use".
Disabling Public IP Addresses: After the operation, the public IP status will change to "disabled".
3. A public IP in the "disabled" state can undergo enabling and returning operations.
Enabling Public IP Addresses: After the operation, the public IP status will change to "in use".
