For the love of God, don't use PureVPN ! They have been proven in court to log traffic, despite claiming not to.[1] [1] https://cyberinsider.com/vpn-logs-lies/
They are one of the few VPN providers that give out public IPv4 addresses, and you can even get a static one. So, if you are using them for having a public IP, not for privacy, please continue doing so.
That could come in handy for hosting things behind double NAT.
