| What is Vpn How It Works |
now at home you've probably got some kind of Route or Modem from your Telephone Company from your "Internet Service Provider(ISP) and then that's connected to your desktop maybe by an Ethernet cable to your Smartphone over Wi-Fi maybe to your Laptop over Wi-Fi.
It gets to the Server the server will then Reply with some information that will come back through the Internet into your local Telecommunications provider down through to your Modem and then back onto your PC or onto your Android Smartphone.
now while all that data is rushing around the internet.
It needs to know where it's going and four things to know where they're going and they need an Address it's the same with the 'Postal Service' is the same when you want to go and visit somebody and it's the same with data on the internet.

Now your Modem your Router has probably been assigned an IP address from your ISP and what happens in is that when your data goes through the internet every piece of equipment.It touches every router every server it touches knows that IP address especially when it gets to the web server at the other end that web server will probably log that IP rests and log what it is that you've requested there is done that is not because it's trying to spy on you but because actually trying to connect collect data about the number of people that clicked into the website when the peak periods are and for data analysis basically for traffic analysis,but of course there's another thing that we need to know about IP address and that is they're assigned in blocks.
so if you have an IP address all of your neighbors and all the people in your area will have the same IP addresses within the same block and there is a database that tells you where these blocks of addresses are assigned,That means that when the data arrives at this Webserver you're connecting to.
It has a pretty good idea of where you are from certainly at the country level most definitely at the city level and maybe even down to within a couple of blocks of where your actual house is.
If you don't believe me go to Google & Search "what is my IP address" and you'll see what information that can be found out for about you just by going to that web page just from your IP address.

They can come to my ISP and say give us that data depending which country in depending on which laws are enacted that can be a quicker or a longer protest can be more difficult can be with more supervision with less supervision but basically every state around the world has access to that information there's not only governments we need to be worried about for example if you're in a coffee shop you're sitting in 'Starbucks' and you're thinking great I've got coffee I've got free internet.

The Wi-Fi point is open they actually know that data is encryption it's very easy to get hold of passwords to get hold of lifts or lists of websites that are being accessed it's even possible to get hold of contents of emails.Now of course there are software levels of encryption 'for example- Whatsapp just implemented end-to-end encryption so that was captured it would be more difficult for the hacker to get the contents of your messages however an open free heighth Wi-Fi hotspot is basically open for access both for good and for bad things so please please do not do any online banking or access website like PayPal when you are connected to your coffee shops Wi-Fi just don't do it.
now another interesting thing about IP addresses and about 'Geolocation' is that if I try to access content that is a video content particularly that is for a particular country if I'm outside of that country I don't have access to it and let's just take a simple example let's say "I'm traveling and I want to get access to my video streaming service I can't if I'm outside of the country,Now that that's because the IP addresses that arrived at the video streaming server it says that my IP address isn't in this country I'm going to block access.
That some types of content is blocked depending on which country you're in and another interesting thing actually is that pricing is different depending on which country you're in.
Now you can try to buy some maybe some cloud storage or maybe an online service and if you try to buy it in maybe in the 'United States' it will be a different set of pricing if you try to buy it in 'Europe' and also in fact Expressvpn recently a study where they found out that actually if you buy airplane tickets the price of exactly the same flight or exactly the same number of people from exactly the same Airport is different depending on which country you actually connect from.
When you try to buy those tickets so Geo fencing Geolocation actually changes things about how we access the Internet ! how we purchase services and how we buy goods,depending on where we are

This Encrypted connection to this client who has connected to me now that allows for a whole bunch of possibilities For example-first of all your local Telecommunications provider and your local government have no idea about the sites that you're accessing when you go through the VPN it's all encrypted.
Now once it goes beyond the VPN once it comes out the VPN server of course it then goes back into the open it goes back pass through all the different routers and things it needs to get to the website and the website itself will register the fact that certain address has come to it but the address now will be that of the VPN server it also.
Means that actually it thinks I'm in a different country so if I'm trying to access media videos streaming content,if I'm trying to buy things then actually it might set the prices or give me access or block access now depending on where the VPN server is not depending on where I am and thirdly,If I'm using open Wi-Fi then actually now that initial connection from my laptop out to the Internet is actually completely encrypted.

Now how does this work what do you need to do!
what the first thing need to do is get yourself a VPN service and there are different VPN services available on the internet.
personaly i'll recommend Express VPN they're really good guys.
When you connect,when you subscribe what happens is,you get a username a password and a list of servers in Europe servers in,America servers,In South America servers and Asia servers all around the world.
Basically you want to connect now create a Virtual Private
Network a tunnel from my laptop from,My PC from my Smart Phone to this particular server in this particular country.
On Android that's really easy to do,in fact Express vpn have an
app you just download the app you put in Username a Password and then you just tap the server that you want to connect to and it will create that tunnel that connect that encrypted connection to that server.
You can also do it manually through the settings page you can create VPN connections and that's the same on Windows you can do that Windows and do it on IOS .you can do it on Linux you can do it in 'Chrome' even do it on certain types of Reuters.

This all sounds great but are there some 'Downsides' ,There are a few downsides the first one and of course is that you're sending your traffic deliberately maybe in the opposite direction to where the services that you need.
so if I'm in Europe and maybe I make a connection to a VPN that's in Asia and then I try to access a website that in America what's happening now is I have to send the data halfway across the world and then half across the world.
Again to get to that server so of course is going to be slower your routing,the traffic all over the place and it's going to be slower than if you were connecting directly to that service also it could be slower because the VPN provider has a limited number of servers and it has a limited number or bandwidth.
so therefore if there are lots of clients or it's a particularly busy time of day then connecting is going to be slower because I'm actually busy with all the other people.
while it is an expensive VPN service provider and a cheap one is the amount of bandwidth and the number of servers they've got.
that's something to watch for when you're choosing a VP service provider and of course the other thing is that some countries actually find have made a VPNs illegal.you do it won't take much for you to do some research to find out if you're in certain countries you try to connect via a VPN actually that is a founder productivity and actually that active in itself could get you into trouble more than maybe accessing certain types or website.
The other thing is that some services actually block access when they see that a VPN is being user making strides to try to block VPN access and when it sees an address but it's Recognized Previously as a VPN server.it will just block access and say you can't get in here.
So as a summary whenever you connect to the internet an IP address is used to route traffic to the server and back again the server will probably log that address and it will also be known by your phone company.
The government has access to that data if it uses the right legal framework to ask the phone company for that information but also just the mere fact that you've used an IP address it actually can give away quite a lot of information about where you are,when you're using public Wi-Fi hotspots,when you're buying things online or these things are open and these things are controlled depending on where you are inthe world.
which means you may not have access certain things you may have to pay higher prices for certain things.A VPN allows you to connect to another server in another country and then to connect further onto the internet it has the advantage that a different geolocation which means you can get around certain access restrictions and it's encrypted.

which means that if you were using like your local coffee shop those day that data is now encrypted my name's from an authoritative.
