The Predecessors Of The VPN
Their efforts led to the creation of ARPANET , a packet switching network, which in turn led to the development of the Transfer Control Protocol/Internet Protocol .
The TCP/IP had four levels: Link, internet, transport and application. At the internet level, local networks and devices could be connected to the universal network and this is where the risk of exposure became clear. In 1993, a team from Columbia University and AT& T Bell Labs finally succeeded in creating a kind of first version of the modern VPN, known as swIPe: Software IP encryption protocol.
In the following year, Wei Xu developed the IPSec network, an internet security protocol that authenticates and encrypts information packets shared online. In 1996, a Microsoft employee named Gurdeep Singh-Pall created a Peer-to-Peer Tunneling Protocol .
What Is A VPN And Why You Need One
The best VPNs can help secure your web traffic against snoops, spies, and anyone else who wants to steal or monetize your data.
Have you ever connected to a public Wi-Fi network and wondered if someone, somewhere might be able to see your online activity? It’s an entirely reasonable concern, considering the forces arrayed against your privacy. With a virtual private network , you can protect your information from prying eyes and regain a measure of privacy online.
How To Fix VPN Speed Issues
Is your VPN too slow? Here are a few ways you can speed up your VPN connection. But remember, your VPN can only be as fast as the speed you get from your ISP.
Disconnect and reconnect. You never know sometimes a reset can make a difference.
Change servers. Experiment and see if you get faster speeds on a different server. Some VPNs can auto-connect you to the fastest available server at any time.
Try a wired connection. Wi-Fi is usually slower than Ethernet. Youll likely get faster speeds if you connect your computer to your router with an Ethernet cable.
Close down other apps. The more apps that are funneling data through your internet connection, the slower everything will feel.

How Does A VPN Work
A VPN works by encrypting communications on the device you are using, be it smartphone, laptop, or tablet. It sends data through a secure tunnel to the VPN providers servers. Data is encrypted and rerouted to whatever site you are trying to reach. Paid-for VPN services, such as ExpressVPN, can mask your IP address so you can browse online securely.
Note If There Is A Dns Leak
If your IP is intact, oftentimes your DNS address can give your location away. DNS servers convert plain text URLs to numerical IPs. Now, if your IP is secure, but the DNS bears the actual location, then cyber criminals can swoop in and hijack your data. Leaky DNS can allow them to use it to access your information. DNS hijacking does exist and is a grave problem.

How Can My Ip Addresses Leak
A VPN needs to protect your IP address. Each internet connection has a unique numerical IP address that can be used to identify it on the internet. You want that to remain private because it carries information about your location and it can be used to link your browsing data to your identity. This is why you should use a VPN for your internet connection.
IP leaks happen most frequently when your VPN connection drops and tries to reestablish itself afterward. This is exactly why most VPN providers, such as NordVPN, include a kill switch that disables your connection completely if its not protected. IP leaks happen especially often with free VPN providers and ones that dont have a kill switch.
If you notice that your real IP has leaked multiple times, or youre using a VPN without a kill switch, its time to switch out your VPN provider. NordVPN is a great option, and you can find out more in our NordVPN review.
Is Using A VPN Safe For Banking
Because a VPN encrypts the data you send, such as when you enter your log-in credentials, it can protect you while you are visiting your banks online portal. Snoops wont be able to see your log-in information if you first connect to a VPN. This is especially helpful if you must access your online bank through a public Wi-Fi connection. You should only do this in an emergency because such online connections are so vulnerable to hackers. But by logging onto public Wi-Fi through a VPN, you can block your browsing activity from cybercriminals, hackers, and other spies.

Selecting A Secure VPN Provider
It is also important that you choose a VPN provider that you can trust. While your ISP cannot see your internet traffic, your VPN provider can. If your VPN provider is compromised, so are you. For this reason, it is crucial that you choose a trusted VPN provider to ensure both the concealment of your internet activities and ensure the highest level of security.

What Should A Good VPN Do
You should rely on your VPN to perform one or more tasks. The VPN itself should also be protected against compromise. These are the features you should expect from a comprehensive VPN solution:
- Encryption of your IP address: The primary job of a VPN is to hide your IP address from your ISP and other third parties. This allows you to send and receive information online without the risk of anyone but you and the VPN provider seeing it.
- Encryption of protocols: A VPN should also prevent you from leaving traces, for example, in the form of your internet history, search history and cookies. The encryption of cookies is especially important because it prevents third parties from gaining access to confidential information such as personal data, financial information and other content on websites.
- Kill switch: If your VPN connection is suddenly interrupted, your secure connection will also be interrupted. A good VPN can detect this sudden downtime and terminate preselected programs, reducing the likelihood that data is compromised.
- Two-factor authentication: By using a variety of authentication methods, a strong VPN checks everyone who tries to log in. For example, you might be prompted to enter a password, after which a code is sent to your mobile device. This makes it difficult for uninvited third parties to access your secure connection.
How To Install A VPN Connection On Your Smartphone
As already mentioned, there are also VPN connections for Android smartphones and iPhones. Fortunately, smartphone VPN services are easy to use and generally include the following:
- The installation process usually only downloads one app from the iOS App Store or Google Play Store. Although free VPN providers exist, its wise to choose a professional provider when it comes to security.
- The setup is extremely user-friendly, as the default settings are already mostly designed for the average smartphone user. Simply log in with your account. Most apps will then guide you through the key functions of the VPN services.
- Switching on the VPN literally works like a light switch for many VPN apps. You will probably find the option directly on the home screen.
- Server switching is usually done manually if you want to fake your location. Simply select the desired country from the offer.
- Advanced setup is available for users requiring a higher degree of data protection. Depending on your VPN, you can also select other protocols for your encryption method. Diagnostics and other functions may also be available in your app. Before you subscribe, learn about these features to find the right VPN for your needs.
- In order to surf the internet safely from now on, all you have to do is first activate the VPN connection through the app.

VPN Providers For Consumers
This is just a small selection of the available VPN providers. There are some really good VPNs on the market, a lot of mediocre VPNs and many more bad, misleading or even dangerous VPNs.
At VPNOverview.com we analyze developments in the VPN industry, read independent audit reports and monitor lawsuits involving VPN providers.
Unfortunately, quite a few VPN providers have fallen off their pedestal over the years, for example because lawsuits showed that they secretly kept logs of users . In addition, there are also some VPNs that are linked to questionable governments.
Choosing a reliable VPN is therefore a must after all, you redirect all your internet traffic via this party. That is why you must be able to rely 100% on the good intentions and integrity of the VPN provider you choose.
Can The Government Track You If Youre Using A VPN
As mentioned before, governments can determine whether you’re using a VPN service. For example, the so-called Great Firewall of China uses DPI and other methods to recognize and block VPN traffic. Fortunately, NordVPN’s obfuscated servers help address some of these VPN detection methods, so they’re great if you’re connecting from a region with strict censorship. They hide your VPN connection by making it look like regular internet traffic.
But can traffic hidden by a VPN be monitored? It depends on the VPN. If the VPN has a no-logs policy, even if the government approached the VPN provider, the provider wouldn’t be able to hand over your activity logs because they don’t have any to begin with.
Some VPN services agree to install backdoors for the government, allowing agencies to monitor user traffic. For example, government-approved VPNs are allowed to operate in China. However, considering the country’s tendency to control all online communications, a legal VPN in China is very likely to have backdoors.

Can You Be Tracked If You Use A Free VPN
Free VPNs need to make their money somehow, and that’s often done by selling your data to third-parties. Some free VPNs will monitor and log your general connection information. This includes your IP address, the IP address of the website you’re trying to visit, the connection time, and the amount of data transferred. As you can see, tracking this information pretty much gives away everything you’re doing online anyway, and offers no privacy making the point of a VPN useless.
What Is A VPN And How Does It Work
When you switch it on, a VPN creates an encrypted tunnel between you and a remote server operated by a VPN service. All your internet traffic is routed through this tunnel, so your data is secure from prying eyes along the way. Because your traffic is exiting the VPN server, your true IP address is hidden, masking your identity and location.
To understand the value of a VPN, it helps to think of some specific scenarios in which a VPN might be used. Consider the public Wi-Fi network, perhaps at a coffee shop or airport. Normally, you might connect without a second thought. But do you know who might be watching the traffic on that network? Can you even be sure the Wi-Fi network is legit, or might it be operated by some nefarious individual?
If you connect to that same public Wi-Fi network using a VPN, you can rest assured that no one on that network will be able to see what you’re up tonot other users snooping around for would-be victims, nor even the operators of the network itself. This last point is particularly important, and everyone should keep in mind that it’s difficult to tell whether a Wi-Fi network is what it appears to be. Just because it’s Starbucks_WiFi doesn’t mean it’s really owned by a well-known coffee purveyor.

Check out our list of the best VPNs if youre not sure which provider is worth your time. Then, feel free to connect to your VPN. In other words, use its interface and pick any server. To get easier-to-understand results, we recommend connecting to a VPN server not located in your country.
Ensure that your VPN session is active. Your VPN app should show you a message that reads “Connected” or “Connection Active,” or its interface could turn green. Once that happens, you’re set to check if your VPN is working correctly. So, let’s proceed.
VPN Test With No Leaks
Below is a leak test result from our NordVPN review:
Above, you can see there are no leaks with the IPv4 address matching the VPN location. IPv6 was blocked and there were also no WebRTC leaks. Finally, NordVPNs encrypted DNS resolvers are handling all DNS requests. This is a perfect test result with no leaks detected.

Who Can Track Me Online
When online you can be tracked by:
- Internet service providers. ISPs can see what you do online and even curb your traffic. However, a VPN hides your IP, encrypts your traffic, and protects your online privacy.
- Government agencies and other similar entities. They can approach ISPs or online service providers to obtain data about you or just use their own tracking methods.
- Cybercriminals. They can track you and steal your data by intercepting your traffic via public Wi-Fi. However, a VPN protects you from this by encrypting your data. Even if the Wi-Fi youre connecting to is compromised, your data will still be protected.
Here are some of the ways you can be tracked online even when using a VPN:
How To Turn On A VPN Kill Switch
You can find the option to enable a kill switch in your VPNs settings. On Windows and macOS this generally only involves ticking a box or toggling a switch, but there can be exceptions.
On Android and iOS the process can be more complicated. Your VPN may not support a kill switch on mobile, or it may require access to your devices settings to set one up.
Heres a video demonstrating how to turn on a VPN kill switch. Weve used ExpressVPNs Windows app as an example:
ExpressVPN’s kill switch is called ‘Network Lock’ on both desktop clients.

Pros And Cons Of Using A VPN At Home
Using a VPN at home is preferable, advised even, but it isnt always essential. The main reason it may not be necessary, is that your internet activity should already be shielded by your password-protected Wi-Fi network. The other concern is connecting to a remote server can slow your connection speed.
However, the pros of using a VPN at home largely outweigh the negatives. The main benefit is completely securing your internet from external hackers, as well as preventing your own ISP using your data against you by selling it to third-party companies. It also allows you to watch geo-blocked content at home at your leisure.
Access To Any Content In Any Place
While Hulu may frown upon your use of a VPN to stream the latest Criminal Minds episode in a country where the content isnt offered, this VPN usage is not illegal , and it helps provide a useful workaround to content restrictions.
VPNs spoof your location, making it seem as if you are browsing from another place. That means you can get your Criminal Minds fix even if its not available locally.
