What is a VPN? – Gary explains

hello my mention is Gary Sims from anger Authority now VPN stands for virtual private network and maybe you’ve heard that period in association to privacy and to geolocation but what exactly is it how does it manipulate and what can it do for you well let me explain now before we dive into VPNs let me tell you a little bit how the internet runs now at home you’ve probably got some kind of route or modem from your telephone company from your internet service provider 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 and so on now inside of your house when your laptop talk to your PC or your phone talk to your PC that’s part of your private network and that doesn’t go out onto the internet it stays inside your live but the moment you open a web page somewhere out on the internet that data flows through your modem down into your neighbourhood phone company and then out across the internet and it will walk across the internet until it gets to the server the server will then reply with some information that will come back through the internet into your regional telecommunications provider down through to your modem and then back onto your PC or onto your Android smartphone now while all that data is hastening 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 there are different blankets of addressing or different types of addressing that go on but at the highest level each of these containers of information have what’s called an IP address now the IP address is you’ve probably seen them there those 4 digit from 0 to 255 with scatters in between them so maybe 1 7 8.30 4.67 speck 120 something like that 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 bit of rig it strokes every router every server it strokes knows that IP address especially when it gets to the web server at the other end that web server will probably log that IP ress and log what it is that you’ve sought 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 beings that I 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 blamed in blocks so if you have an IP address all of your neighbors and all the people in your locality will have the same IP addresses within the same block and there is a database that tells you where these blocks of addresses are designated that be interpreted to mean 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 going to see what is my IP address comm and you’ll encounter what information that can be found out for about you just by going to that web page exactly from your IP address now of course ordinarily that’s not a number of problems the facts of the case that I go to Twitter isn’t going to cause any problems for anybody however if I start to access substance that is maybe a bit more sensitive maybe I have a physical problem I want to read about all needs I may have an feelings problem maybe I want to look about a top topic that is taboo in my culture in its own country that I live in then suddenly these different that these servers know where I’m from and know about my IP address is a bit more concern more than that most governments throughout the world have a system where they can demand from an ISP the actual person that was assigned a specific IP address on a particular date so if they then are now in and “theyre saying” well we want to find out who was reading about this particular topic they can come to my ISP and say give us that data depending which country in depending on which regulations are reenacted that can be a quicker or a longer protest can be more difficult can be with more supervising with less supervision but basically every regime around the world has access to that info 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 enormous I’ve got chocolate I’ve got free internet now these open public Wi-Fi hotspots are quite dangerous it’s not difficult for anybody with a bit of technical knowledge to take a laptop and sit in a coffee shop and to captivate all of the data packets the hell is flowing around in the Airways and because the earth 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 face-lifts or registers 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 simply implemented end-to-end encryption so that was captured it would be more difficult for the intruder to get the contents of your messages nonetheless an open free heighth Wi-Fi hotspot is basically open for access both for good and for bad things so delight satisfy do not do any online bank or access website like PayPal when you are connected to your coffee shops Wi-Fi just don’t do it ok 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 illustration let’s say I’m move 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 was of the view 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 State it is gonna be a different create 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 airliner tickets the price of exactly the same flight or exactly the same number of parties 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 deepens things about how we retrieve the Internet how we obtain services and how we buy goods depending on where we are now what a VPN does is it allows you to create a tunnel a tie-in from your home computer to a server somewhere else in the world and that connection is encrypted and then when I access something on the Internet it goes through that passageway and then it arrived at that other server and then it goes on to the Internet and it will finally arrive at the web server or the service I’m trying to use but the IP address will no longer be my IP address that’s on that data packet it are really be the IP address of the VPN server and what happens is that when it replies it the response to the VPN server the VPN services are I was aware that this is for it actually need to go back down 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 regional telecommunications provider and your local government have no idea about the places that you’re accessing when you go through the VPN it’s all encrypted now formerly it goes beyond the VPN formerly 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 facts of the case that particular address has now come to it but the address now lies in the fact that of the VPN server it also means that actually it recollects I’m in a different country so if I’m trying to access media videos streaming material if I’m trying to buy things then actually it might give the prices or give me access or block access now will vary depending on where the VPN server is not will vary depending on where I am and thirdly if I’m employ open Wi-Fi then actually now that initial alliance from my laptop out to the Internet is actually entirely encrypted so if there was somebody sitting in the coffee shop connecting with a tablet trying to a laptop trying to connect catch all the containers actually they won’t be able to come that much because it will all be 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 a myriad of different VPN services available on the internet person recommend Express VPN they’re really good guys now when you connect when you subscribe what happens is you get given a username a password and a inventory of servers servers in Europe servers in America server servers in South America servers and Asia servers all around the world and basically you say I want to connect now create a virtual private structure a passageway from my laptop from my PC from my hand Royd smart phone to this particular server in this particular country now on Android that’s really easy to do in fact expressvpn have an app you simply download the app you put in username a allotment and then you exactly tap the server that you want to connect to and it are generating that tunnel that are linked that encrypted connection to that server you can also do it manually through the creates page you can create VPN communications and that’s the same on Windows you can do that Windows and make love on OS 10 you can do it on Linux you can do it in Chrome OS you can even get it on on certain types of Reuters so actually a VPN is available across countless many types of machines and then formerly that connection is made all your data traffic all of your trash you’re doing we’ll “re going through” that VPN out into the Internet in a different country and then further abroad where it needs to go now this all sounds great but are there some downsides now 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 an internet site that in America what’s happening now is I have to send the data halfway all over the world and then half across the world once again to got to get that server so of course is going to be slower ok your routing the traffic all over the place and it’s going to be slower than if you were connecting instantly to that busines now 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 buyers 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 parties now while it is an expensive VPN service provider and a inexpensive one is the amount of bandwidth and the number of servers they’ve got so 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 I won’t mention them now but you do it won’t make much for you to do some study 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 got to get into trouble more than maybe accessing certain types or website and the other thing is that some business actually block access when they see that a VPN is being user netflix but in the news recently because it’s clearing steps to try to block VPN access and where reference is finds an address but it’s recognized previously as a VPN server it will time block access and say you can’t get in here so as a summary whenever you connect to the internet an IP address used in order to street congestion 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 intelligence but also merely the mere detail that you’ve exerted 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 in the world which means you may not have access certain things you may have to pay higher prices for certain things now a VPN allows you to connect to another server in another country and then to connect further onto the internet it has certain advantages that a different geolocation which means you can get around sure-fire access regulations and it’s encrypted which be interpreted to mean that if “youre gonna” exercising like your local coffee shop those day that data is now encrypted my name’s Gary Sims from an authoritative II do if you did delight do give it a thumbs up don’t forget to subscribe to Andrew aura T’s YouTube channel you really should download
