I am going to ask like 7000 customers to add that IP into some kind of whitelist.
If I achieve this, it is mandatory for me to keep this IP so I don’t have to ask these 7000 customers again, to change that IP to something else.

• What should I be aware of to not to lose this IP?
• If I delete a droplet will I lose it? If yes, what should I do in such a case that I need to reinstall my ubuntu server to fresh new installation, but to maintain the IP?

Thank you
