How a VPN Works?

To understand how a VPN works, you have to look at what goes on when you connect to your ISP or Internet Service Provider. When you get onto your ISP, you are going online through a set IP that works within an area determined by that ISP. Your traffic will go through the ISP servers and will be reviewed regularly by your ISP.

A VPN is very different. As you use a VPN, you will work on an encrypted link or tunnel. What happens here is that you can disguise the IP that you are using when you get onto a VPN. This means that you can simply get online with a fully secured setup.

To make this work, you would have to get online and then log on to your VPN. You would then be given the option pick out a particular virtual server that you will reach. This could entail a server from any particular part of the world although it is best to choose a server in one region that is relevant to what you are doing.

If you’re in the United States then you could choose virtual server from another part of the country to avoid local work or school blocks. Meanwhile, you could use a server in Australia if you are trying to reach content that is only available in Australia.

Why Is a VPN Needed?

A VPN is a necessity in that it ensures you will stay fully private and secure as you are online. Your ISP will not be able to see your data as it has been fully encrypted. Your traffic is fully routed through the VPN server, thus ensuring your data cannot be found by your ISP.

Also, you will have to get your IP address changed if you want to do more online. When you change your IP address on a VPN server, you will be interpreted by the online world as being from a certain part of the country or world based on that new IP.

People who try to track your online activity will be led to the VPN server. Therefore, your actual IP address will never be exposed.

More importantly, a VPN ensures that you can get online a public Wi-Fi hotspot without having your data exposed. Hackers are known to steal online data in public Wi-Fi connections because that data is not fully encrypted or secured. With a VPN, you are ensuring that you will keep yourself online and secure.

What Can You Use a VPN For?

You can use a VPN to get away from monitoring in any form. When you use a VPN, you are concealing your online activity from everyone. You will keep your activities private from your online service provider while also ensuring the government does not try and spy on your activities.

Also, you can avoid censorship when you use a VPN. By using a different connection point, you are essentially getting away from any firewalls or blocks installed by your ISP, your workplace or your school. More importantly, you can get beyond any particular censorship firewall that has been installed by your local government.

You can also use a VPN to access items that are off limits to you because of your geographic location. That is, an American could get access to videos from Canada or the United Kingdom when on a VPN. You can also get access to videos that you normally see at home but cannot fairly reach while you are on holiday.

But Is It Legal?

A VPN is fully legal for use in most parts of the world. This comes as it ensures a sense of privacy that people have an inherent right to.

However, VPNs are illegal in some countries where the government is extremely restrictive. These include places like China and Iran. Various services have managed to get beyond those restrictions in such countries although you would have to do a bit of research to see what is out there.

What About Logs?

Whatever you do online, you should watch for how logs can work. Logs are often used by some VPNs to review what people do as they are online.

Fortunately, most VPNs will not use these logs as they respect the privacy of those who use these services. You should still watch for how some VPNs are required to keep logs based on where they are located. This is especially the case for VPNs in countries around Europe.
