When your’e logged to VPN, can your ISP see the exact IP you get from the VPN, or only some general (And maybe constant) IP that connects you to the VPN server?
A VPN server has at least two IP addresses. The entry IP and the exit IP. The ISP can only see that you are sending encrypted traffic the entry IP. It can not see the exit IP address. The exit IP address is seen by the destination that you are connecting to.
