For people searching what is VPN used for, in simple words, your search ends here. A VPN hides your IP address. It encrypts your internet connection, making your internet surfing private, but that’s not all it can do. This guide contains everything that you need to know about VPNs.
Due to advanced technologies, our online lives have become even more important than physical ones. Therefore, we should learn to protect it. Certainly, one of the most popular and efficient tools that help to protect one’s privacy and security on the Internet is a VPN.
So, let’s explore all the details about what is VPN, and more below.
Advertisement What is VPN, & What Is It Used For? [Learn from the Basics]
A VPN or Virtual Private Network is a tool that creates a protective tunnel between your device and the internet. Encrypting your data and masking the IP address provides a protected channel through which hackers, the government, or prying eyes cannot access your information.
A VPN keeps your actions confidential. Whether you’re accessing something from home, in a coffee shop, or from anywhere in the world, a VPN is your solution.
If you’re still confused about what is a virtual private network VPN used for, then the simple answer is to bypass geo-restrictions. For example, you want to access BBC iPlayer, or Hotstar, but you don’t live in the country where these services are available. Then? Well, you will use a VPN to access them.
What are the Important Characteristics of VPN?
Since you know what VPN is, you might be interested in the important characteristics of VPNs. Those are:
- Encryption: VPNs use several protection measures to ensure the privacy of the transmitted information.
- Anonymity: A VPN successfully disguises the user’s IP address, providing anonymity and making it practically impossible for websites or other third parties to track the users.
- Remote Access: VPNs offer a secure distant connection to the company’s networks, supporting employee productivity through telecommuting.
- Geo-Spoofing: The user can also use the VPN to change the IP address to another country, breaking some website’s regional restrictions.
- Data Integrity: VPN ensures that the information transferred to and from the network is as it is, in its original format, and has not been modified.
How Does a VPN Works?
It is interesting to know how a VPN functions. When you use a VPN, it reroutes your traffic to a VPN server before sending it to the destination website. This not only conceals your IP address but also encodes data so nothing can be read by those who will try to intercept it. Here’s a step-by-step breakdown of how a VPN connection works:
- Connection to a VPN Server: First, open your VPN application. Next, choose your desired connection. Tap the connect button, and you will be connected in 1-2 minutes.
- Encryption of Data: When data is transferred from your device to the VPN server, it is encrypted using advanced algorithms. This encryption allows the data to be intercepted, but unauthorized persons cannot access or understand it.
- IP Address Masking: Connecting to a VPN server means assigning a new address that could be from the VPN’s geographical location instead of the actual IP address. What it does is conceal your actual physical location. Further, it broadcasts your IP address to that of the VPN server country.
- Secure Data Transmission: The data continues from the VPN server through the internet and gets to the desired destination website. When a VPN is used, only the IP address of the VPN server you are connected to can be seen by the website, instead of the real IP address. Hence, you remain anonymous.
How Many Types of VPN are There?
VPNs are of several types, and these differ according to the various needs of computer networks. Some of the VPNs are as follows:
- Remote Access VPN
- Cloud VPN
- Site-to-Site VPN
- Mobile VPN
- SSL VPN
What are VPN Protocols?
A VPN Protocol is a collection of rules that regulate data transmission between your device and a virtual private network (VPN) server. VPN programs use these protocols to provide a secure and dependable connection.
- OpenVPN: OpenVPN is a cryptographic protocol specially designed to preserve security. The VPN-compatible protocol is available for setup with an OpenVPN server.
- Point-To-Point Tunneling Protocol (PPTP): PPTP is not widely used because there are better, more reliable options with higher and more advanced data protection standards.
- WireGuard: WireGuard is a good choice because of its performance efficiency.
- Secure Socket Tunneling Protocol (SSTP): Microsoft developed SSTP for Windows users. Its connectivity is limited to specific systems. Hence, it’s used rarely.
- Layer 2 Tunneling Protocol (L2TP): It connects the user to the VPN server without encryption, often used with IPSec for complete connection, encryption, and security.
How to Choose a VPN?
Here are the key points which you must keep in mind while choosing a VPN:
- Ensure the VPN has good speed: Many providers struggle to maintain Netflix streaming, which might cause missing the latest Elite season 8 episodes. So, choose a VPN wisely.
- Check out feedback: Review opinions from ordinary users and specialists to understand how effectively the VPN performs.
- Shared IP addresses: Ensure the service offers shared IP addresses.
- Server availability: More servers translate into faster browsing, as traffic is distributed across multiple servers.
What are the Benefits and Limitations of a VPN?
The table below contains the benefits and limitations of a VPN:
| Benefits | Limitations |
|---|---|
| Enhanced Privacy | Reduced Speed |
| VPNs encrypt your data, making it unreadable to anyone who intercepts it. | VPN connections can slow down your internet speed due to encryption overhead. |
| Access to Restricted Content | Potential Connection Drops |
| VPNs allow you to bypass geo-restrictions and access content unavailable in your region. | VPN connections can occasionally drop, exposing your real IP address. |
| Improved Security on Public Wi-Fi | Cost |
| VPNs protect your data from hackers on insecure public Wi-Fi networks. | High-quality VPN services typically require a subscription fee but allow users to unblock platforms like Hulu, HBO Max, etc. |
| Anonymity and IP Masking | Complexity for Non-Tech Users |
| VPNs hide your real IP address, ensuring anonymous browsing. | Setting up and using a VPN can be challenging for non-technical users. |
| Protection from ISP Tracking | Legal and Policy Restrictions |
| VPNs prevent your Internet Service Provider (ISP) from tracking your online activities. | Some countries have restrictions or bans on VPN usage. |
| Secure Data Transmission | Possible Data Logging by VPN Providers |
| VPNs ensure that your data is transmitted securely, reducing the risk of interception. | Not all VPN providers have strict no-logging policies, which could compromise your privacy. |
Is A VPN Only Meant for Online Security?
Surfing the Internet via VPN is a preventive measure that boosts your security and privacy. This is because data encryption means that the data being transferred to servers cannot be easily read; IP address anonymity ensures that a user’s IP address is hidden. So, the bad guys cannot control your activities online.
With a VPN service running, people using the same network as you will only see military-grade encrypted data if they look at your connection.
No matter what bothers you most: hackers, governments, or website trackers, a VPN offers a rock-solid shield for your online identity.
What is the difference between VPN and a Virtual Network?
The difference between both is:
| Feature | VPN (Virtual Private Network) | Virtual Network |
|---|---|---|
| Purpose | Provides secure, encrypted connections over the internet for privacy and security. | Facilitates communication and resource sharing within a defined network infrastructure. |
| Usage | Used to protect online privacy, secure data transmission, and bypass geo-restrictions. | Used to create a network of virtual devices and services that communicate over a physical network. |
| Security | Encrypts data to protect against interception and ensure privacy. | Implements network segmentation and isolation for security within the network. |
| Scope | Extends a private network across a public network, such as the internet. | Extends a private network across a public network, such as the Internet. |
| Components | VPN client, VPN server, encryption protocols, and tunneling protocols. | Virtual switches, routers, subnets, and network interfaces. |
