What is a VPN? VPN Benefits and Uses and Works – Guide
Return to routine. VPN stands for Virtual Private Network. Using a VPN is a simple and efficient way to increase your security, privacy and freedom online. When you use the Internet, your device constantly exchanges data with other parties on the Internet. A VPN creates a secure tunnel between your device (e.g. smartphone or laptop) It is the internet. VPN allows you to send your data to an external server through an encrypted and secure connection: the VPN server. From there, your data is forwarded to its destination on the Internet. Redirecting your internet traffic through a VPN server has several advantages. First, it helps to hide your online identity. Second, it protects your data. And third, it allows you to use the Internet more freely. A VPN can do many things, and that’s because it changes your IP address. Each computer has a unique IP address when connected to the Internet, which tells other computers where you are in the world. With a VPN, you connect to another computer (a server) before going online, letting other computers know that you are somewhere else. Most VPN services allow you to choose this fake location yourself. With a new IP address, there are many possibilities. Streaming platforms like Netflix, for example, have different content for different parts of the world. A VPN changes your digital location and gives you access to streaming libraries in other countries.
How does a VPN work?
A VPN uses something called tunneling to establish an encrypted internet connection. When you use the internet, all your activity is separated into packets of data. Typically, third parties can use a process called deep packet inspection to read these packets of data and track everything you do online. But tunneling encrypts each data packet and encapsulates it in another data packet. When data packets are encrypted, they are re-encoded into a new format. This new code, called ciphertext, requires a decryption key to read, so only authorized parties can decrypt encrypted data packets. This means that when third parties such as your ISP come to inspect your data packets, they cannot. Instead, the content inside will be unreadable by your VPN connection. So why is this process called tunneling? This has to do with how these packets of data are transmitted. When you use a VPN, your data packets are sent through a secure tunnel through a VPN server before reaching their original destination.
VPN Benefits
A VPN is beneficial in many ways. It also has several advantages that make it ideal for everyday use when compared to other types of digital tools and software.
Prevent ISP Tracking
Your ISP plays a key role in your online experience as it provides you with access to the Internet. But that means they are uniquely positioned to monitor everything you do with that access. From your search history to your communications and data usage, your ISP can track all your traffic. If they use this ability to share your information with third parties, interfere with your connection, or encourage you to upgrade your broadband package, ISP tracking has a negative impact on your personal privacy and online experience. Fortunately, you can put a stop to this using a VPN. With a VPN connection, your data will be protected from your ISP.
Make public Wi-Fi secure
As more aspects of our daily lives move online, consistent and reliable Internet access is a must. That’s why public Wi-Fi networks and hotspots seem to be the ultimate convenience. But they are also the trap final. Because they are free and public, anyone can use these networks. This means that when you use them, you are sharing network access with people you don’t know and can’t trust. With a little knowledge, other users of public Wi-Fi networks can spy on all other users on the network and intercept unencrypted traffic. But if you are using a VPN, they will not be able to spy on you. This is especially crucial in cases where you rely solely on public Wi-Fi hotspots and networks, such as when you are traveling.
Change your location online
Your physical location and IP address have a huge influence on how you use the Internet. Marketers can use geo-targeting to identify your physical location and serve you targeted ads; repressive governments can use censorship to prevent you from accessing important information; Schools and workplaces may use firewalls to prevent you from accessing legitimate websites and services. With a VPN, though, you can take back control of your online location. By changing your IP address with IPVanish, you will no longer face unfair restrictions imposed on your real IP. This allows you to access the Internet with the freedom you deserve, with the added benefits of privacy, security and anonymity.
protect your identity
As we have established, your IP address is a unique identifier. And that means it can be directly associated with you. With a little social engineering, a tech-savvy stranger can combine your IP address with other resources to identify your name, physical address, phone number and much more. Together, they can use this information to steal your identity or impersonate you online. But when you use a VPN, your IP address will be masked with the IP address of your VPN server. Furthermore, each IP address is shared among IPVanish users, so no online activity can be traced back to a single user.
VPN Advantages
A VPN isn’t the only digital tool people turn to to increase their online privacy or change their online location. Other services such as encrypted messaging apps, Tor and proxies are popular. But a VPN comes with some key advantages:
