[Hint] VPN provider for a static IP

I have a raspberry in a private home connected via fiber with a “popular” provider in Italy.
To have a static IP I am using a vpn provider that worked fine giving a real IP and it was quite cheap. Now this provider is switching to a new way giving a static IP behind a NAT, service I don’t like too much.
I cannot switch the connection provider easily.
So I am asking here for some hint for a new vpn provider, reachable from Italy giving “real” IP.
