In Basic and Adv+SG zone one can acquire new/secondary IPs for his instance, in the NIC section of an instance there used to be a button "Acquire new IP" or similar (alas I have upgraded and no longer have access to 4.3 UI who still had this).
The NIC section was also listing any secondary IPs the instance may have had. The capability remains only in the API at this moment.
This feature was useful and in use, please advise how to bring it back.
