A smart DNS proxy server is a DNS server that has been configured to direct clients to a transparent proxy server for a subset of specific internet sites, usually for the purpose of allowing access to content on those sites that would otherwise be restricted due to geo-blocking.[1]

Operation[edit]

A smart DNS proxy server enables a client, such as a computer or mobile device, to access region-restricted or blocked content from anywhere in the world. A connection between the client and the site serving restricted content is established through a proxy server located within the approved areas for streaming or downloading the content. As with a virtual private network (VPN) proxy, this allows a user to stream or download content which is normally blocked for viewing by people within that region. Unlike VPN proxy, a smart DNS proxy does not encrypt communications and does not direct all internet traffic via the proxy. Instead, it selectively directs traffic for certain sites, typically those of popular streaming services, via the proxy. This is achieved by overriding selected DNS entries so that DNS queries resolve to the address of the proxy rather than the real server. Only the relevant information needed for a user to view the digital media content is routed via the proxy. This is information related to a user's geographical location.

Setup[edit]

A smart DNS proxy does not require a user to install any third-party applications or software on a device. A user can immediately access region-restricted or blocked content once the user has changed the DNS of a device to connect with a smart DNS server. A smart DNS proxy can be installed and set up across an entire network of devices such as desktop computers, laptops, mobile smart phone devices, smart televisions, and Internet-capable gaming consoles, and is compatible with all mobile operating services including Android, Apple's iOS, Blackberry and Windows Phone.

Data interception and re-routing[edit]

Smart DNS proxies allow users access to region-restricted content by intercepting and re-routing data or information being exchanged by proxy servers located within the region which has been approved for viewing. A smart DNS proxy does not encrypt data. A Smart DNS cannot be used for traffic encryption or security purposes. Due to the lack of end-to-end encryption, data packets can be seen by the ISP or on any intermediate network. For additional security and encryption virtual private network (VPN) services should be used.

Security risks[edit]

The security risks of using a smart DNS proxy server are very similar to that of using any other proxy server, as a compromised or malicious proxy has the ability to perform man-in-the-middle attacks on any unprotected traffic passed through it. Since the user is not aware which parts of his traffic are redirected and intercepted by the Smart DNS proxy, this risk extends to all sites the user accesses, not just those the smart DNS proxy is configured to intercept. For this reason it is quite common to install a second router in the house specifically for media streaming.[citation needed]
