/pv-vpn Prime Video Geolocation

Hi, This is not so much an AWS question as it is a Prime Video Question. Does anyone know what provider Amazon uses to verify geo-location information of client streaming IP's. My network users are complaining of getting a "/pv-vpn" error while trying to use prime video services when there are no VPN's on the network. It is my belief amazon has the wrong geolocation information in regards to my subnet.

Could it possibly be CloudFront?

Any info helps, thanks!
