Hey there,

The private IP you are seeing is used to automatically bind a Floating IP to your Droplet when assigned via the control panel or API. You can look at this for more details on Floating IP’s. If you want to use Floating IP’s with this Droplet, you would not want to remove the private IP from eth0.

In terms of your eth1 question, that may be best answered in a support ticket. Please reach out with more details in a support ticket and we can take a closer look for you,

Happy coding,
