How does your service work, exactly? If I understand correctly, unlike other methods of working around the region restrictions of these streaming websites, you are not actually offering any sort of VPN service, but rather something related to DNS? I would love to know how this works, as the only possible way of using DNS for this purpose that I can think of is switching our own DNS servers to yours, which would translate the domain of the corresponding streaming site (Netflix.com, for example) to an IP address belonging to a U.S. server of that streaming website. That being said, I would still be skeptical of something like this working and would be surprised to find that there aren't any more checks done server-side to make sure that your own IP address was actually from the United States. I am more interested in the technical aspect than anything else, as I am inside the U.S. myself so this service would not actually change anything for me.
It's very simple actually
The DNS server itself does not need to be in the USA but the Proxy behind it
So the DNS will resolve any site normally except the ones in the zone file that will be redirected to the proxy to solve it
I can do a vouch copy, or you need to provide a 1-3 day trial as suggested, most dns services don't work any more with Netflix. So people don't want to wste their money unless it truly works.
I'll PM you with the test details after 1 hour
