VPN is short for virtual private network and it allows you to create a secure connection to another network over the Internet. During your long haul on the Internet, you must come across some websites that say that access is not allowed. This could be due to a variety of reasons like the website being banned in your country or your IP address being blacklisted.|
This is where the VPN comes into play. A VPN can be used to access region-restricted websites, shield your browsing activity from prying eyes on public Wi-Fi, and more. In this article, we study the uses of VPN and why it is absolutely necessary for you to use one.
What is a VPN?
For those with academic leanings, A virtual private network (VPN) is a network that is constructed using public wires — usually the Internet — to connect to a private network, such as a company’s internal network. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. It secures the private network as these systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
When you connect your computer (or another device, such as a smartphone or tablet) to a VPN, the computer acts as if it’s on the same local network as the VPN. All your network traffic is sent over a secure connection to the VPN. Because your computer behaves as if it’s on the network, this allows you to securely access local network resources even when you’re on the other side of the world. You’ll also be able to use the Internet as if you were present at the VPN’s location, which has some benefits if you’re using public Wi-Fi or want to access geo-blocked websites.
In layman terms, when you type in www.google.com in your VPN connected desktop browser or smartphone browser, instead of your browser pinging directly to Google servers, it pings your VPN service providers servers. The VPN servicer providers servers then ping Google servers. Which means that the VPN acts as a shield in your connection and prevents Google to directly access your IP or location.
When you browse the web while connected to a VPN, your computer contacts the website through the encrypted VPN connection. If you’re using a USA-based VPN to access Netflix, Netflix will see your connection as coming from within the USA.
While surfing Google is harmless, imagine you want to download a torrent from a website which is banned in your country. In such a case, when you type in the torrent URL (say thepiratebay.org) instead of pinging the TPB website directly your desktop/smartphone will ping the VPN servers which are whitelisted in your country and allow you untethered access to the torrent that you want.
Uses for VPNs
In the early times of Internet, VPN’s were a luxury which only a few could afford. But now a days with tons of VPN service providers, you can get an encrypted VPN connection relatively cheaply or freely. VPNs can help you do the following things :
Accessing blocked websites : As explained above, if thepiratebay is banned in your country, a VPN can help you solve the issue by making your ISP believe that you are accessing a legal website and allow you to download torrents.Accessing geo-blocked websites : If you are trying to access a particular service like Netflix, Hulu, Pandora etc from outside of United States, a VPN will allow you access to such region-restricted services if you connect to a VPN servers in the USA.
Hide Your Browsing Activity From Your Local Network and ISP : As was proved by Edward Snowden, the governments from the world over snoop on their citizens for various reasons. If you’re using a public Wi-Fi connection, your browsing activity is visible to your ISP, government, and almost everybody. If you want to hide your browsing activity for a bit more privacy, you can connect to a VPN. If you are using a VPN, the ISP/government will only see a single, secure VPN connection because all your web traffic through a secure VPN tunnel. While this can be used to bypass connection-monitoring by your Internet service provider, bear in mind that VPN providers may opt to log the traffic on their ends.Bypass Internet Censorship: Governments from the world over block access to websites that are deemed harmful to their citizens. China blocks almost every western website for the fear of evoking pro-democracy ideas among its citizens. India bans almost every adult website under the assumption that its citizens are harmed by watching porn. VPN can help you bypass such censorships with ease.
Downloading torrents or files: Torrent downloads are the single biggest reason that VPN services are so popular today. In some countries, torrent websites are banned absolutely which in some countries, the ISPs throttle the download speed if you are downloading a torrent file. VPNs solve both these problems with ease.Using a VPN
