Many individuals have heard about VPNs — or use a VPN service already — but don’t understand far more than easy methods to turn one on. So, how exactly does a VPN work? Read on to learn in regards to the basics of VPNs to maximise your online security and privacy.
What Is a VPN?
VPNs are tools designed to guard your sensitive information and safeguard your privacy whilst you’re connected to the web. They hide your Web Protocol (IP) address, which is a string of numbers that represents each device connected to the web. This address is answerable for directing requests and data to their intended destinations.
IP addresses are pretty convenient — the web as we understand it is determined by them — but in addition they present some problems. Because an IP address represents your device, anyone who knows it could trace it to seek out out your browsing history, what you are doing online and even your physical location.
VPNs offer an answer to this issue via routing, which is the means of choosing a path to your online traffic across a number of networks. They redirect your traffic through its distant servers, concealing your IP address and encoding your data.
The Basics of VPNs (Virtual Private Networks)
Downloading and installing a VPN isn’t any harder than doing so for every other software application. Most VPNs are compatible with all major operating systems, including iOS, Android, Microsoft Windows, Mac and Linux, so that you’re likely covered regardless of your chosen system.
The advantages of using a VPN include:
- Hiding your physical location: VPNs ensure hackers, stalkers, government agencies or anyone else cannot decipher where you’re.
- Protecting your privacy: You may surf the online in peace, knowing your activity is not monitored or tracked by an outdoor party.
- Accessing geo-blocked content: You may watch movies, hearken to music or play video games your provider would otherwise block as a result of your location.
- Stopping targeted ads: Advertisers cannot bombard you with targeted advertisements when they cannot track your online activity.
- Keeping cybercriminals at bay: VPNs can prevent hackers from accessing and using your personal information against you.
- Avoiding bandwidth throttling: Your web service provider (ISP) won’t have the opportunity to decelerate your connection speed if it could’t tell what you’re using the web for.
How VPNs Work
VPNs streamline a series of complicated technical processes behind the scenes to determine a secure connection. Fortunately, you do not need a Ph.D. in programming to make use of this technology or understand its basics. With just a little bit know-how, you’ll be able to surf the web with a VPN like a professional.
Establishing a VPN Connection
The very first thing you might have to do is hook up with the web along with your VPN. This should not be more complicated than tapping the connect button, clicking a chosen area of your screen or toggling a virtual switch.
The VPN client will hook up with your ISP after which locate the closest server location in its network. Once the connection has been established, you should utilize the web knowing that your online activity is kept protected from prying eyes. Still, at this point, the method has just begun.
Encryption of Data
Encryption is what protects your personal data from being intercepted by third parties. VPNs scramble your web traffic, making it not possible to decipher unless you might have the encryption key or password. With an encrypted connection, you haven’t got to fret about cybercriminals getting their hands on sensitive information like your passwords or bank card numbers.
The most effective encryption available is AES-256, also called “military-grade encryption,” since it’s probably the most reliable technology available to guard top-secret data. AES stands for Advanced Encryption Standard, and the numbers after it represent the encryption key’s length. The important thing may be 128 bits, 192 bits or 256 bits — the upper the number, the longer and more complex the encryption key.
The best VPNs use AES-256 to encrypt your data before sending it to its servers. This implies anyone trying to observe or access your information won’t know what it’s, nor will they know who or where you’re.
Data Transfer Through a Virtual Tunnel
Once your information is encrypted, it’s sent to the VPN’s server. Though it’s already encrypted, VPNs use a tunneling protocol to move your information, which adds an additional layer of security. This technology wraps your encrypted data inside other data, making a secure tunnel that stretches out of your device to the VPN server.
Examples of well-known VPN protocols include PPTP, L2TP, IKEv2/IPSec, OpenVPN, and WireGuard. Various kinds of security protocols are best fitted to speed, security or specific tasks.
Decryption on the Server Level
After your data reaches the VPN server, the VPN sends your request to whatever corner of the web you were attempting to access, whether that is one other server, a web based service or a web site. Most VPNs won’t take a look at your data during this process as a part of their no-logs privacy policy. At this point, your encrypted data reaches the VPN server. The VPN then sends your request to whatever corner of the web you were attempting to access, whether that is one other server, a web based service or a web site. Most VPNs won’t take a look at your data during this process as a part of their privacy policy.
Rerouting the Data
Finally, the request you made reaches its destination. As an instance you are trying to observe a hilarious cat video posted on a web site. The VPN server gets your request and asks the web site for the info to observe the cat video. The web site has no idea who’s asking for this information behind the guise of the VPN server. When the VPN server gets a response from the web site in the shape of knowledge for the cat video, it codes that data with AES-256 encryption and sends it to you thru one other encrypted tunnel.
Although this process sounds lengthy, all of it happens in just a few moments at most. You will see the web site load shortly and the cat video will begin to play before it.
How Do I Know If My VPN Is Working?
Most VPN apps will indicate whether your web connection is secure. Don’t desire to take the VPN at its word? There’s one other method to check your connection.
First, be sure your VPN is off and go to whatismyipaddress.com. This site will inform you what your IP address is and supply other information connected to your IP address, just like the name of your web service provider and the town, region and country you reside in. Snap an image or write down your IP address and related information.
Next, exit the web site, connect your VPN and return in (refreshing the page also works). In case your VPN works, your IP address needs to be different from the one you wrote down. Every other information also needs to be different.

How much extra data gets used is determined by your VPN, but some use as much as roughly 15% — or more.
Is There a VPN That Works with Netflix?
Should you’re not getting a VPN for greater online privacy and security, likelihood is you are getting it to access geo-blocked content. Geoblocking is when a service, akin to Netflix, Hulu and Prime Video, limits the content available to users based on their location.
In case your favorite TV show is not available in your current location, all you might have to do is select a VPN server in a rustic where it does show up.
