You are able to attach multiple Public IP addresses to each instance using the Modify Dialogue. This will take 1-2 minutes and will require your instance to be powered down. Please follow these steps:

1. To attach an additional IP address to an instance, you will need to first allocate a new IP address to your account. If you have yet to do this, please follow the steps in this article (Link). 
2. Navigate to the "Instances" tab of the OrionVM Panel.
3. If your instance is currently running, please shutdown your instance. 
4. Click the Modify () to open the Modify Dialog. 
5. You will be presented with the Modify Dialog:
   
6. Drag the IP you wish to attach from the "Available" column to the “Attached” column.
7. Click "Modify" to close the Modify Dialog. You should notice that the new IP address is attached to the Instance in the table. 
8. Start your instance (by pressing the  button) with the new settings. 

Your instance should now have the new IP address attached. If you have any issues with carrying out this operation, please submit a support ticket to support@orionvm.com.au.
