Smart DNS vs VPN

Let’s admit that we feel extremely tempted and a bit confused when it comes to choose between two products that at first glance appear to us equally useful. This can happen to us when comparing two services which are extremely good: Smart DNS and VPN.

Even though we wrote earlier what is a VPN service and what is a Smart DNS service, even if we are aware of the criteria, the properties that are the foundation of these two services and the possibilities they offer, we need to know to make a distinction between them, so that we can make a good choice. In order to make the right decision and to identify which of them is most appropriate service to our needs and desires, we need to extract the advantages and disadvantages of each product.

Smart DNS is a service that unblocks regional restricted websites, on the other hand VPN offers privacy and security when browsing the internet. So let’s discover the advantages and disadvantages of these two services.



VPN is a service that allows you to change your IP address choosing from IP addresses made ​​available by multiple servers located in different countries. One of the biggest advantage of our VPN Service, is that with VPN your identity is hidden when browsing. What refers to unblocking, you might use VPN to unblock a restricted site by choosing your IP from the region the blocked website comes from.


Unlike Smart DNS, VPN won’t let you enjoy your provider’s original speed. As VPN speed depends on many factors and it is usually 30% lower than original one.

Smart DNS


Smart DNS is a service that unblocks regional restricted sites that do not expose their content to users from other countries. It is a simple method to access regional restricted websites from anywhere in the world using original provider’s speed, without many changes in your device. Smart DNS comes with an advantage: it offers direct access to the pre-unblocked sites with no loss of speed. So, what does Smart DNS do is: directly unblocks each site. By the way is good for you to know that we have one of the largest list of unblocked websites on the market.


The disadvantage that Smart DNS has, is the fact that it doesn’t offer privacy and anonymity while surfing the internet as VPN does. With Smart DNS your IP is not hidden. Also the VPN service is used in order to get a better personal security while being connected to a public WiFi, which is another VPN advantage.
If you need a service that will allow you to watch restricted media with your original speed or, in other words will let you to unblock regional restricted websites, then Smart DNS is the right service for you.

    Actually, I find that I get BETTER throughput using a VPN for general surfing… I have a 50/5 Mbps ISP plan, but have seen as high as 137 Mbps down and 20 Mbps up when connected to a nearby VPN server.
