Absolutely. No IP address is displayed. I have
www.neinonline.com forwarded to my personal computer for testing of a site I am developing. This is set up as a temporary forward, no masking. I am sure that I could set it as permanent. Bizarre, I know, but worth a try.
I think that the masking actually changes the URL that you have typed to reflect the location to which it is forwarded. Nonmasking retains the URL that you typed. As I said, counterintuitive. Maybe this is an anomaly, but it sure works for me.
Attached is a .jpg of how I have the settings.
