Unlocator is able to remove location based restrictions on websites and other internet services by simply using their DNS servers. I'd like to understand how this works on a technical level.
I can't find much explanation on their website. The homepage doesn't give many details away:
All Internet connected devices use so-called DNS servers to navigate the Internet. Unlocator is a DNS service with a twist, as our service will hide your real location from all the major streaming services. You will see no bandwidth loss using our technology, and only the sites listed on our supported list are affected by our service.
I thought I understood roughly how DNS works, but it seems there's more to it! I didn't think this kind circumvention of location restrictions was possible unless you used a VPN.
