Start with the fact that VPN systems do not provide your IP address.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Is the IP address you’re referring to the IP address given by the ISP?
Yes. Your VPN can only assign an IP it uses internally. What traverses you and the VPN is an ISP IP address.
Also, your ISP cannot view your data as it is encrypted between you and the VPN, but they do know you two are talking and can see the encrypted data packets.
