I need it to give to my host to whitelist them so i can connect over FTP
What you're saying here doesn't make much sense, what type of Host are you talking about?
Also if this is a Host you pay to do business with, then it doesn't make much sense to connect to the FTP via a VPN...
The point of using a VPN like this is to remain as private and anonymous as possibe, that means you certainly don't go out there and start telling companies you use a VPN and then give them IPs to whitelist...
Also between a host and the ftp, this should be your own personal ftp that comes with your hosting plan and the only people that have access to it, is you and the host, so again, no point in a VPN...
So I'm at a loss here as to why a vpn over your ftp...
