What is a VPN: What does it do and how is it used
VPNs mask your IP address and physical location while encrypting your internet traffic so that no one can know who you are, where you are, or what you’re doing online. That’s why VPN virtual private network – It is a private tunnel when ordering online.
This comprehensive beginner’s guide to VPNs will explain exactly how a VPN works and why you should use one. You will also learn how to choose a VPN service based on your needs. VPNs aren’t just for desktop or laptop computers — you can set up a VPN on your iPhone, iPad, or Android phone, too.
How does a VPN work?
A virtual private network (VPN) works by using encryption protocols to route all of your internet traffic through an encrypted tunnel – a virtual private network – between your computer and a remote VPN server. This hides your IP address and secures your data, preventing others from intercepting it.
Without a VPN, all of your internet traffic will likely be exposed to your Internet Service Provider (ISP), government, advertisers, or other people on your network. for this reason VPN connections enhance your online privacy and security.
A VPN passes your internet traffic through an encrypted tunnel between your computer and the VPN server.
What does VPN mean?
VPN means virtual private network.
VPN is virtual Because it’s created digitally – there is no physical cable that goes from your device directly to the VPN server.
VPN is Spread Because it encrypts your data and hides your IP address.
VPN is an extension network Because it creates a connection between multiple computers – your device and the VPN server.
How to use a VPN
Here is how to use a VPN app to instantly encrypt your data and hide your IP address:
Download and install AVG Secure VPN.
Open the VPN app on your computer or mobile device.
Choose a VPN server and connect.
What is VPN encryption?
VPN encryption is the process of using data encryption (encryption protocols) to create a secure tunnel through which your data travels. If anyone checks your VPN connection, they will see mixed data. Only your device and the VPN server you are using can encrypt and decrypt or decrypt your data.
While many encryption methods, or AlgorithmsExisting, most VPNs use the 256-bit AES (Advanced Encryption Standard) algorithm. This level of encryption is so secure that it is used by banks and governments around the world – as well as by AVG Secure VPN.
What are VPN protocols?
A VPN protocol is the set of rules or instructions that establish the connection between your device and VPN proxy servers. Each VPN protocol is a combination of encryption methods and transmission protocols. You can change your VPN protocol in the settings of your VPN app.
Renowned for its safety and speed, OpenVPN It is one of the leading VPN protocols. As an open source protocol, its source code is available for anyone to check out.
If exploitable vulnerabilities are found, they are quickly addressed by the community of developers who support them. VPN connections that use open source code also allow anyone to verify that the developers aren’t doing anything suspicious themselves.
IKEv2 (Internet Key Exchange version 2) is a powerful protocol that is usually combined with IPsec for security. Like OpenVPN, IKEv2 uses 256-bit encryption, and both can provide fast connections. IKEv2 is especially popular with mobile devices because it can easily switch between mobile data and Wi-Fi networks. But unlike OpenVPN, it is not open source.
L2TP (Layer 2 Tunneling Protocol) was developed by Microsoft and Cisco as a successor to PPTP (discussed below). Responsible for establishing a VPN connection, L2TP is often combined with IPsec for security.
PPTP (Point-to-Point Tunneling Protocol) is an older and less secure protocol that is still popular with free VPN services. While it is easier to setup than the more advanced options, PPTP is riddled with known security flaws and must be avoided If you are looking for a secure connection.
Why is it important to hide your IP address?
Your IP address is a unique set of numbers that identifies your device when connected to the Internet. Just as the postal service uses street addresses to deliver mail to the right people, IP addresses ensure that Internet traffic is sent to the right computers.
Your IP address associates your device with your Internet service provider as well as your general geographic location. This is how content streaming platforms work Geoblocking – Restrict content by region. Based on your IP address, you can only watch content that is available to viewers in the part of the world where you live.
VPN hides your actual IP address By showing the IP address of the VPN server you are using instead of your IP address on the public internet. This prevents anyone from finding your IP address. Some VPNs group multiple users under a single shared IP address, anonymizing your online activity.
Pair this IP masking with encryption, and your online activities will remain completely private from ISPs, hackers, and government surveillance. A VPN protects you in many ways.
AVG Secure VPN enhances your privacy by hiding you and other VPN users behind a single shared IP address. This makes it extremely difficult for anyone to associate your web activity with you again, since many users share a single IP address at any one time. It is just one of the many ways AVG Secure VPN provides to keep you safe on the Internet.
What does a VPN do?
There are many benefits to using a VPN. By encrypting your Internet connection and hiding your IP address behind a new one (often in another part of the world), a VPN allows you to:
Secure your data over public Wi-Fi networks.
Overcome regional content blocks.
Access to blocked websites.
Bypass Internet censorship.
Prevent ISP tracking.
Prevent price discrimination.
Not only does a VPN connection encrypt your browsing and other web traffic, it can give you access to a more free internet by letting you choose where you are globally. This combination of security and flexibility makes VPNs extremely versatile. Some people even use a VPN for gaming.
The original purpose of VPN technology was to connect remote workers to corporate networks. Many companies still use VPNs for this purpose, but in this article, we are referring to consumer VPNs that are used to enhance your personal security and privacy online.
So what is the use of a VPN? Let’s find out.
Secure your data over public Wi-Fi networks
The convenience of free public Wi-Fi often comes with a loss of security. Since anyone can go to an unsecured Wi-Fi network, there’s no way to know exactly who’s calling at what time, or what they’re doing. It’s easy for a hacker to sit on a public Wi-Fi and intercept all the traffic flowing through it.
If you log into your bank account, check your email, or check out on social media, a hacker can capture your login credentials. Any messages you send or personal data you transmit can be intercepted and used for extortion or identity theft. The dangers of public Wi-Fi are almost endless.
because A VPN connection encrypts your connection to its serverAnyone trying to eavesdrop on the public network will see nothing but bullshit. This is a big part of VPN protection: ensuring that no one can access your data.
Stream from anywhere
Due to licensing restrictions, streaming platforms feature different content libraries in different countries around the world – this is known as Geo-blocking. If you are traveling abroad and want to catch up on your favorite shows from home, you may find that they are not available in your current location.
VPN lets you Bypass site-based content blocks By giving you an IP address in which country your VPN provider has a server in. If you choose your home from the list of servers, it will be as if you have never left home. And when you install a VPN on your phone or mobile device, you can really stream from anywhere.
Access to blocked websites
You may find that some websites are blocked in certain scenarios or locations – such as while you are at school or at work. VPNs make you avoid content blocking so you can access blocked sites, even if you are somewhere that restricts access to certain sites.
Your encrypted VPN connection passes through any restrictions on Bring you the sites and services you want, regardless of the content blocks on your network.
Many countries limit access to the Internet. China blocks Google, Facebook, and all associated services, such as Gmail, Google Maps, WhatsApp, and Instagram. a A VPN connection can avoid censorship blocking In the same way it can circumvent geo-blocking content and website restrictions.
Evade ISP Tracking
Without a VPN, your ISP (Internet Service Provider) can track all of your online activities: the websites and services you use, when you use them, and for how long.
Many people don’t understand how much influence an ISP has over your data. In the UK, your ISP will store your online history for a year – that’s all you read, watch, view and click on. And in the United States, your Internet service provider can store your browsing history and sell it to the highest bidder — such as an ad network, data broker, or subscription service — without your consent.
Because of how a VPN works, it protects you from this kind of privacy invasion. Because your device’s internet connection is encrypted, your ISP can’t monitor exactly what you’re doing on the internet, and They can’t see your browsing history.
Prevent price discrimination
Price discrimination occurs when E-commerce sites offer different prices to different people based on their perceived ability to pay. Online retailers use a variety of criteria to calculate the price of an item for any given viewer – device type along with demographic information such as your real-world location.
Airlines are often accused of price discrimination, in which flight prices change depending on when you buy, where you are and other factors. You can counter location-based price discrimination by using a VPN to give yourself an IP address in another part of the world.
Why is online privacy so important?
The Internet is expanding exponentially. As more people start using smart devices, they risk exposing intimate personal data online. And with ISPs tracking, storing and selling the browsing history, habits and behavior of their customers, it is essential to secure your private data.
Your personal information must be personal. Without privacy protection, you could expose yourself to identity theft and other cybercrime, as well as to tracking by advertisers, your ISP, and your government.
Can I still be tracked online when using a VPN?
If you pay for your VPN with a credit card, your VPN provider will likely know who you are. Since you are connecting to your VPN from your device, they will also have your IP address. But that’s it – most VPNs don’t monitor your online activity, and many have explicit no-logs policies that prevent them from collecting any information about what you do while using their services.
A VPN protects your data during its journey between your device and the VPN server. If you connect to websites that use HTTPS encryption, your data will be safe throughout its entire journey. But if you are connecting to unsecured websites, your data will be exposed after it leaves the VPN server.
While VPNs can prevent people from tracking you based on your IP address, they cannot block other web tracking methods such as cookies and browser fingerprinting. And Once you log in to the siteLike a social network, this site can still track what you click, share, and “like” even if you’re using a VPN – because you’re logged in.
