Who I have the same questioned this topic

What exactly should the Digital Setting VPN Parameters/Settings be? I have reason to believe my iPhone XR was remotely jailbroken and since then sometimes the VPN Server says "local" and other times the server address is the following: 

us-central-x.lazerpenguin.com

Please help. Any guidance and direction and confirmation of the correct/incorrect VPN Server address would be very helpful.

Sincerely,

Brady C.
