EDIT: A few months after, it turns out I was wrong. Yes Netflix is now blocking VPN… A full blog some will come soon.
However,if you want still want to use a VPN, you mighj want to have a look at IPVanish IPVanish for a good all-purpose tool. However, even it if might work in some cases, it is not guaranteed that it will allow you to bypass Neftlix location checks. It will however gives you extra privacy against your ISP for example.
Lately, Netflix released an official blog post explaining why media contents differs by countries, and NO, Netflix not blocking VPN.
Proxy vs DNS
According to the blog post, we can read that :
Some members use proxies or “unblockers” to access titles available outside their territory. To address this, we employ the same or similar measures other firms do. This technology continues to evolve and we are evolving with it. That means in coming weeks, those using proxies and unblockers will only be able to access the service in the country where they currently are.
Netflix is enforcing their method of detection of tools such as DNS unblockers and proxies. However, VPN are a complete different stories.
While it is pretty easy, today, to discover if someone is using proxies or such “unblockers”, it is VERY hard and uncertain to discover if someone is using a VPN.
To make it short, a proxy will send headers to the Netflix server saying something like : “hello I am a proxy”. It modifies all the data you send to the Netflix servers adding some kind of footprint about the proxy it is passing the data through. Yes transparent proxies exist, but they are generally (not always) easier to detect than VPN.
In this other hand, using a VPN, is exactly like you were plugging your computer inside another location, and using it from there. Let’s say you are from Europe, but on vacation in the US and then can enjoy legally Netflix US from your hotel room. This is what a VPN does, it doesn’t add any header, nor it modify the packet (=information / data) you send to the Netflix server.
Netflix not blocking VPN
Hence my article, I want to correct the mass media saying that Netflix is cracking down on VPN users. They are not, and even if they would, they couldn’t do it efficiently due to the nature of VPN. A VPN can be completely transparent, that’s its purpose, hence totally undetectable.
However, some VPN technologies / set-ups can be “guessed” (hello, “port fail” vulnerability) to be VPN and then blocked easily (with some amount of false positives), a majority of VPNs, can not be detected AT ALL.
Some well know VPN providers could also be blocked according to the IP ranges they use, but they’ll change their IP, and other less know providers could slip through the net.
To sum up : No, Netflix NOT blocking VPN anymore than it used to do it (if it did). Text analysis 101, in the blog post that started all this, NOTHING can tell us that Netflix is cracking down on VPN (even if they are, which I highly doubt).
