Virtual Private Network, or VPN, is not a new term for netizens they regularly use VPNs for things like unblocking torrent websites, watching online content, and staying safe and private online.

A VPN is also helpful for people who have to stay in contact with their office, even if they are
working from a different location.

VPNs are useful tools when you want to bypass geo-restrictions and use the internet for, whether for fun work. A VPN also helps protect your privacy and personal data from theft to keep you safe on the internet.

But how does a VPN do all this? How does a VPN work? We explain the workings of VPNs in
simple terms.

How do VPNs work?

Every device that goes online has an IP address. Your IP address reveals information about you and your device, including your location as well as your ISP.

What is a VPN? How does it work

A VPN changes your IP address virtually. Even if you don t need to change your virtual
location, a VPN protects your privacy by giving you a different IP address that can t be used
to identify you. However, a VPN can also be useful if you want to access online content from
another country.

When you connect to the internet using a VPN, all your internet traffic passes through the VPN
before it reaches you. The VPN becomes the mediator of your data.

If you connect to a VPN server location in another country, So, it seems that you are sitting in that country and using their internet there. Since the VPN gives you a new IP address for the country you are connected to, geo-restrictions are all but gone.

A good VPN will also encrypt all your data using AES-256 bit encryption.

If anyone tries to intercept and steal your data, all they will receive is meaningless strings of letters and characters.

So a VPN kills two birds with one single stone it bypasses geo restrictions and protects your
data and privacy. For users who value their privacy, VPNs are essential as a method to protect
their internet freedom and safely use the internet

Pros and cons of using a VPN

Let’s take a look at the advantages and disadvantages of using a VPN.


  • Protects your data online
  • Allows you access to geo-restricted or censored websites
  • Lets you watch region-restricted content on various streaming platforms
  • Keeps your online activity hidden from your internet service provider
  • Maintains your anonymity online


  • Legally restricted in some countries
  • Potentially unstable connections

As the pros heavily outweigh the cons, VPN apps remain an essential tool for netizens to make sure their digital privacy and personal data are protected

Uses of a VPN

Here are some of the widespread applications for VPNs in both the private and business sector.


Online multiplayer games are on the rise. What started as a hobby; has become a career path for many people. People spend hours playing games to earn their living, and maybe make a name for themselves.

VPN for gaming

They love to games with other better players to improve their game. But geo-restrictions sometimes do not allow them to join in regional rooms of any other country. It is when using a VPN app that helps them.

Using the VPN, they can pass these restrictions and play games on foreign servers with minimum lag. It allows gamers to improve on their game and make their name in the gaming community.


Torrenting refers to a huge network of people who download files from each other’s devices.
Sometimes, the files people want to share are quite large, so you need to make sure you have unlimited bandwidth and optimum speeds.

VPN for Torrenting

The speed is dependent on how many people are sharing that same file. Torrenting is also used to download movies, software, TV shows, games, etc.

Some countries have blocked torrenting websites. But a VPN can cross geographical
boundaries and allow users to access torrenting websites from countries where they work

Unblocking geo-restricted content

Everyone loves to watch content on streaming platforms. Since the pandemic, online streaming of shows has become one of the most popular pastimes.

Unblocking Geo-Restricted Content

But here’s the problem. Every country has its own media laws, which online streaming platforms have to follow. As a result, some content gets blocked in some countries.

This may include popular and critically acclaimed shows. To stream this content, people turn to VPNs. A VPN allows them to watch content that is available only in specific countries.

By changing their IP address, they change a device’s virtual location and find their way around the geo-block.


Working never stops for some people. Even if they are away from the office, they need to stay
connected with their office; sometimes, they even have to work remotely.

Large companies work on their private network. They have their network set up in their offices
around the world, and they have to keep these offices interconnected.

A VPN helps companies to set up this web. One main router acts as a VPN client, and other routers in offices become the repeaters. Employees have to log into this private connection to access the company’s network

How to use a VPN?

The language and workings of a VPN may sound very technical, but using one is incredibly simple. All it takes is a few taps to make your device secure. Here’s how you can set up a VPN on your device in minutes.

Best VPNs for torrenting, streaming, gamers, and Netflix

Now we know how to use a VPN. Let’s talk about the VPNs available in the market. If you look in the app store or on the internet, you will find hundreds of different VPNs. Some might even be free.

As tempting as they may seem, it is never a good option to use a completely free VPN on your
device. A VPN is supposed to improve your security, but free VPNs take that security away from you. Some may log your data or sell it to make a profit, or compromise your security by not encrypting your data.

A paid VPN encrypts your data before every transfer and makes sure that there is no leak in their servers. You should also make sure they have a no-log policy when it comes to acitivity and connection logs.

Unlike a free VPN, a paid VPN should not reduce your speed. Instead, you can enjoy unlimited
bandwidth and a lag-free experience. It may cost you a bit more, but it’s worth it not to compromise your digital privacy. Here is a list of the best VPNs for you, as reviewed by us
