Hello Ken, Each Google Compute Engine VM can have 1 external IP assigned. This IP can be static or ephemeral. As such, if you are receiving requests with different IPs (i.e. x.x.x.x.bc.googleusercontent.com) they will be from different users/location.
You can refer to this link [1] which has more information on networking of GCE instance. I hope that helps.
