The company said it would clamp down on these proxies or unblockers in a few weeks.
The announcement comes just a week after Netflix went live in more than 130 countries, covering almost the entire globe except China.
Netflix said at the time that all of its shows would not be available immediately to subscribers in certain countries, but that it was working towards resolving that.
"Ultimately, the aim is to provide a service around the world that is more similar than not.
Using VPNs or proxies to virtually cross borders violates Netflix's terms of use because of licensing restrictions on TV shows and movies," a Netflix spokesperson told Reuters. India, Nigeria, Russia and Saudi Arabia were among the 130 countries where the service was launched last week.
"The strategy is simple - they have a responsibility to content owners to only show that content in the geographies for which they have a licence. Enforcing those restrictions is a Netflix responsibility," Brian Blau, research director at Gartner, told Reuters.
