Do you remember these, special codes for DNS servers that would be floating around in their thousands online. You’d simply use one of these servers in order to bypass the restrictions and blocks that Netflix applied based on your location. That is an American Netflix subscriber would switch to the Canadian version as soon as he crossed the border. All Netflix accounts were linked to your actual physical location, not were you normally lived or where you subscribed from.
It was really annoying to have your US version of Netflix replaced by another version just because you were travelling. Of course many of these ‘localised versions’ also naturally contained lots of content in that local language which made it even more frustrating.
These US Netflix DNS codes allowed you to hide your real location and appear to come from the US when you needed. This worked because at the beginning of your session Netflix would use your current location to decide which version you could watch. These DNS servers routed through the US so that your subscription would be also routed through to the US version of Netflix.
It was worth doing, even if Netflix had a version in the country you were in – it was unlikely it would be anywhere near as good as the US one. Some estimates suggest that the US version of Netflix has over 10,000 more films, movies and TV shows than some of the smaller versions.
Unfortunately these DNS codes don’t actually work anymore because of a measure that Netflix implemented last year. It was a move designed to stop people choosing which version of Netflix they watched and force them into their geographically assigned one. The move coincided with Netflix expanding into 150 more countries, which meant that most of the time your Netflix subscription was still useable when travelling.
What they did was to mass block any connection that originated from a ‘commercially’ tagged IP address. This included all DNS, proxy and VPN servers which were all installed in commercial or educational premises and so were assigned a commercial IP address. The only connections that were permitted included those from ‘residential IP addresses’ which were mostly assigned by local ISPs. This meant that unless you were using a home internet connection or one from an ISP then Netflix would be blocked.
This instantly stopped all Smart DNS solutions and codes from working, plus all the proxies and VPN solutions too. There is some recovery happening with the commercial firms now including residential IP addresses in their infrastructure.
