How to Use a DNS Server to Increase Security

As this year is taking shape with worldwide self-isolation, the trend is to move activities online in response to the epidemic. People are looking for a reliable means to protect their devices from malware for work and to broaden their reach for new leisure content. Here’s how to use DNS Server to increase security and work around Geofence.

The traditional way to achieve geofencing is to use a VPN that provides security and privacy protection.
On the one hand, you can use a VPN to achieve privacy and on the other hand allow users to override geo-restrictions.

However, there is another option that works well for individual and small-scale consumers: DNS-based solutions, such as smart DNS and DNS firewalls. They offer more targeted solutions to the problems we face in our daily activities at a lower cost. This differentiates them from traditional enterprise tools that protect extensive business networks.

What is DNS?
In general, the Domain Name System, or DNS, is the way a domain name is located and translated into an IP address. You can compare DNS to a phone book where each domain name is mapped to a specified IP address.

When we surf the Internet, we use domain names like google.com or facebook.com. However, web browsers use Internet Protocol (IP) addresses such as 69.63.181.15 to access the website. What DNS does is match these addresses. When you type a URL in a web browser, it sends a request to a dedicated DNS server that returns a corresponding IP address. The web browser can then use it to access the website. Without such a system, we would have to remember all IP addresses.

At the same time, DNS is much more than just a directory. You can also use it to bypass geoblocking and increase security during web surfing. But does this mean that DNS can change the VPN connection?

Smart dns and geoblocking
Presumably, every internet user has faced a geoblocking problem. You want to watch a new episode of your favorite series on Netflix or click on a video on Youtube. But suddenly, you can see that the error is saying that the video is unavailable in your area. Such limited access to a particular region is called “geoblocking”, and is widely used by video-streaming sites, such as the BBC’s iLiner, Netflix and ABC iView.

The underlying principle is quite simple: every device connected to the Internet has a unique IP address. The blocks allocate IP addresses to Internet service providers (ISPs) who in turn allocate them to customers. This scheme makes IP addresses detectable at a geographic location. Thus, companies may limit access to only IP addresses from a particular region.

The way to trick geoblocking is that you can change your IP address – or do so, so that the website in question will not be able to properly detect it – so that its location seems to be eligible. Smart DNS is a technique that directs a user to a proxy server to mask IP addresses. Because of that, you can get access to geo-restricted content.

how it works
The DNS address specified by your Internet service provider contains information about your geolocation. Smart DNS instead replaces a new Smart DNS server. A smart DNS provider uses a proxy server in the eligible area to view the requested content. Smart DNS server can be located anywhere in the world.

When you are connected to this server, your traffic is routed through it. Smart DNS accepts your connection requests to the server you want to access, and carefully transforms any data in those requests that may have leaked your geolocation.

Modern applications run smoothly on any platform and device with an Internet connection, from routers to smart TVs and video game consoles. These modern apps have a true global network of servers, which unblock the most popular video streaming platforms, including American Netflix, Amazon Prime and HBO Now.

Smart dns vs vpn
At first glance, it seems that the features of SmartDNS and VPN are quite similar. Like a VPN, smart DNS devices hide your actual location. However, unlike a VPN, they do not change the IP address of your device. They only mask their original IP address. With a VPN, you connect directly to a secure local server in another country. You use that server’s internet connection – and its IP address – such as to stream some content.

Another important difference from a VPN is that a smart DNS does not encrypt your traffic. Without data encryption, the connection between your device and the webserver is much faster via a VPN tunnel that masks and encrypts all traffic.
