Netflix and the Smart DNS Fight

SMart DNS is the innovative new technology designed to stop ordinary people getting blocked from their favorite web sites. Many of us discover these blocks when travelling or on holiday, for me it happened years ago when I tried to log onto the BBC website to watch the news and was told because I was not in the UK I couldn’t watch it. I was annoyed, I paid my license fee at home so why should it matter where I happened to be.

Nowadays it’s even more common and in fact most of the larger web sites use geo targeting or blocking to some extent. I certainly don’t think there is a big media site that allows unfettered access to their content to the whole world. Smart DNS changed this and offered an alternative to the usual fix of connecting through a VPN server. Smart DNS doesn’t route your whole connection it just filters the location specific requests and therefore has little impact on your own connection.

If you want to see how Smart DNS works – then this video illustrates how it can be used to bypass these blocks.

As you can see the only modification required is to the DNS settings on your device which is why Smart DNS is so much easier to implement on different devices like Smart Phones, media streamers and even Smart TVs. Unfortunately there does seem to be a downside which has been illustrated by the efforts of Netflix to block use of Smart DNS servers and codes.

The first efforts were successful although not completely, Netflix started to roll out updates to the various Netflix interfaces on device like the Roku. These updates hard codes the addresses of public DNS servers like Google DNS, which meant that any DNS settings you configured would be ignored as the servers were already hardcoded in the the device. This stopped SMart DNS working with Netflix and people were unable to change regions or access Netflix in a country where the media giant hadn’t established a presence. It also was rather unpopular with the owners of these public DNS servers as their servers became flooded with so many DNS requests from millions of devices.

It appeared that they backtracked and removed the static DNS entry requirements. Whether this remains the case, we’ll have to see – Many of the media giants seem more concerned with SMart DNS than they were with VPNs probably because it has the potential to be used on a much wider base of devices and even pre-installed on new hardware without the owners knowledge. Cretainly if the Smart DNS settings are set up a router like this, they’ll effect every device on that network.
