Waxay u badan tahay inaad horay u maqashay VPN , waxayna u badan tahay inaad sidoo kale isticmaashay. VPN^{(A VPN)} waxay u taagan tahay Shabakadda Gaarka ah ee Virtual^{(Virtual Private Network)} , taas oo asal ahaan ka dhigan inay ku siinayso qarsoodi online ah. Asal ahaan, kaliya ganacsiyada waaweyn iyo ururada dawladda ayaa isticmaali jiray adeegyada VPN , laakiin maalmahan, isticmaaleyaal badan oo internetka ah ayaa isticmaala adeegyada VPN si ay u sugaan xogtooda. Maalmahan^(Nowadays) , qof kastaa wuxuu isticmaalaa VPN maadaama ay hubiso in goobtaadu ay tahay mid gaar ah; xogta waa la sir ah inta aad si qarsoodi ah u dhex geli karto internetka.

Maanta adduunka tignoolajiyada sii kordheysa, ma jirto shaqo aan ku tiirsanayn internetka^(Internet) . Internetku^(Internet) maaha oo kaliya qayb ka mid ah nolosheena maalmahan, dhab ahaantii, laakiin sidoo kale waa nolosheenna. Internet la'aanteed, waxaan dareemeynaa inaysan jirin wax jira. Laakin maadaama tignoolajiyada iyo isticmaalka internetka ay si aad ah u korayaan maalinba maalinta ka dambeysa, waxay sidoo kale dhalinaysaa su'aasha Amniga. Markaan ku bixino lacag-bixinta khadka tooska ah anagoo adeegsanayna taleefannada iyo laptop-yada, waxaan u dirnaa faahfaahintayada shaqsiyeed kuwa kale isticmaalaya warbaahinta bulshada. Sidaa darteed^(Hence) , dhammaan taleefannadayada iyo laptop-yadayada waxaa ku jira macluumaad aad xasaasi u ah oo gaar ah oo si cad u baahan in la ilaaliyo oo la sugo.

In badan ayaan isticmaalnaa internetka^(Internet) laakiin ma naqaano sida uu u shaqeeyo. Haddaba, aan marka hore eegno sida uu internet- ku run ahaantii u gudbiyo oo uu u helo xogta.

Sida Internetku u shaqeeyo^{(How Internet Works)}

Maalmahan waxaad ku geli kartaa internetka^(Internet) siyaabo dhowr ah. Sida taleefannada, waxaad isticmaali kartaa xogta mobilada ama isku xirka WiFi kasta. ^(WiFi)Laptobyada ama PC-yada waxaad isticmaali kartaa WiFi ama fiilooyinka haadka. Waxa laga yaabaa in aad haysato modem/router-ka uu desktop-kaagu ku xidhan yahay Ethernet -ka iyo Laptop-yadaga iyo talefannadaada iyada oo loo marayo WiFi . Kahor intaadan ku xidhin xogta mobilada ama modem ama WiFi , waxaad joogtaa shabakada deegaankaaga, laakiin isla markaad ku xidho mid ka mid ah, waxaad ku jirtaa shabakad balaadhan oo loo yaqaan internetka^(Internet) .

Mar kasta oo aad wax ka samayso internetka^(Internet) sida raadinta bogga internetka, waxay marka hore ka soo gaadhaysaa shabakada degaankaaga shirkadda telefoonka ama WiFi -ga shirkadda ee aad isticmaalayso. Halkaa waxa ay u sii jeeddaa shabakad ballaadhan oo ' Internet ' ah oo ugu dambeyntii timaadid server-ka. Mareegta internatka waxa ay raadisaa bogga aad codsatay oo dib u soo celi bogga aad codsatay kaas oo ka duulaya intarneedka soona gaadhaya shirkada telefoonada oo aakhirka ka dhigaysa modem ama data mobile ama WiFi (wax kasta oo aad isticmaalayso si aad u gasho internet) oo aakhirka ka gaadha kombayutarkaga ama telefoonadaada.

Inta aanad codsigaaga u dirin interneedka, ciwaanka la yidhaa IP address ayaa ku xidhan si marka la codsado bogga uu yimaado ay u ogaadaan halka codsiga laga soo diray iyo halka laga gaadhayo. Hadda codsigii aanu ka samaynay safarka shabakada maxaliga ah, shirkadda telefoonka ama modem, internet ka dibna ugu dambayntii webserver ah. Markaa^(Hence) , ciwaankayaga IP-ga ayaa ka muuqda dhammaan meelahaas, iyo ciwaanka IP-ga, qof kastaa wuu geli karaa goobtayada. Bogga shabakadda ayaa sidoo kale geli doona cinwaankaaga IP-ga sababtoo ah gaadiidka badan ee badan iyo ku-meel-gaar ah in muddo ah ayaa la geli doonaa halkaas, oo halkan waxay kor u qaadaysaa su'aasha gaarka ah. Waxay caqabad ku noqon kartaa xogtaada gaarka ah waxayna eegi kartaa waxaad ku samaynayso nidaamyadaaga.

Dhibaatada ugu weyn ee qarsoodiga ah waxay ka dhalataa WiFi^(WiFi) furan . Ka soo qaad^(Suppose) inaad joogtid makhaayadaha qaarkood oo bixiya WiFi bilaash ah oo furan . Ahaanshaha isticmaale internet oo quus ah, isla markaaba waad ku xidhi doontaa oo aad bilaabi doontaa isticmaalkeeda intii suurtogal ah adiga oo aan ogayn in inta badan WiFi -yadan bilaashka ah ay si buuxda u furan yihiin iyada oo aan wax qarsoodi ah la helin. Aad bay u fududahay bixiyaha WiFi bilaashka ah inuu eego xogtaada gaarka ah iyo waxaad samaynayso. Waxa ugu xun ayaa sidoo kale u fudud dadka kale ee ku xiran WiFi isku mid ah^(WiFi)hotspot si aad u qabato dhammaan xirmooyinka (xogta ama macluumaadka) ee shabakadan ku soo dirto. Waxay u fududaynaysaa inay la baxaan dhammaan macluumaadka ku saabsan ereyada sirta ah iyo mareegaha aad gelayso. Marka waxaa had iyo jeer lagula talinayaa inaadan marin macluumaadkaaga xasaasiga ah sida faahfaahinta bangiyada, lacag-bixinta online-ka ah iwm. addoo isticmaalaya WiFi dadweynaha furan .

Markaad gelayso boggaga qaarkood, hal dhibaato ayaa ka dhalata waxa ku jira ama goobtaas waa la xannibay, mana geli kartid. Waxay noqon kartaa sabab waxbarasho ama sabab siyaasadeed ama sabab kale. Tusaale ahaan, Jaamacaduhu^{(Universities)} waxay siiyaan arday kasta aqoonsiga gelitaanka si ay u helaan WiFi -ga kulliyadda . Laakin qaar ka mid ah goobaha (sida torrent iwm), oo jaamacaduhu u arkaan inaysan ku habboonayn ardayda, ayaa xannibay si ardaydu aanay u geli karin iyaga oo isticmaalaya WiFi -ga kulliyadda .

Marka, si loo xalliyo dhibaatooyinkan oo dhan, VPN ayaa soo galay doorka.

Waa maxay VPN ??^{(What is a VPN ??)}

VPN waxay u taagan tahay Shabakadda Gaarka loo leeyahay^{(Virtual Private Network)} ee Virtual . Waxa ay abuurtaa xidhiidh badbaado leh, ammaan ah oo sir ah oo ay la leedahay shabakadaha kale ee aan ammaan ahayn sida internetka^(Internet) dadweynaha . Waxa ay gaashaan ka siisaa shabakadaada deegaanka si wax kasta oo aad samaynayso sida baadhista mareegaha, helitaanka macluumaadka xasaasiga ah, iwm, aanay u muuqan shabakadaha kale. Waxa kale oo loo isticmaali karaa gelitaanka goobaha xaddidan iyo wax ka badan.

Markii hore, VPN^(VPNs) -yada waxaa loo sameeyay in lagu xidho shabakadaha ganacsiga oo ay siiyaan shaqaalaha ganacsiga lacag jaban, oo ammaan ah oo ay helaan xogta shirkadda. Maalmahan^(Nowadays) , VPN- yadu^(VPNs) waxay noqdeen kuwo caan ah. Waxaa isticmaala tiro badan oo dad ah sida arday, shaqaale, madax-bannaanilayaal, iyo safarro ganacsi (kuwaas oo u socdaala dalal kala duwan) si ay u galaan goobaha xaddidan. VPN waxay u adeegtaa ujeedooyin badan:

• Ka ilaali siidaynta xogta gaarka ah iyo kuwa xasaasiga ah adoo ilaalinaya amniga
• Waxay ka caawisaa^(Helps) gelitaanka goobaha la xannibay iyo kuwa xaddidan
• Ka ilaali inaad gasho server-ka shabakadu inta lagu jiro taraafikada culus
• Waxay ka caawisaa qarinta goobta runta ah

Noocyada VPN^{(Types of VPN)}

Waxaa jira dhowr nooc oo VPN ah:

Helitaanka Fog: Helitaanka ^{(Remote Access: )} fog ee VPN^{(Access VPN)} wuxuu u oggolaanayaa isticmaaleha gaarka ah inuu ku xidho shabakad ganacsi oo gaar ah isagoo u siinaya meel fog isagoo isticmaalaya kombuyuutar ama laptop ku xiran internetka^(Internet) .

Site-to-site:  Bogga^(Site) ilaa goobta VPN^{(Site VPN)} waxay u ogolaataa xafiisyo badan oo ku yaal meel go'an inay ku xidhmaan shabakad dadweyne sida internetka^(Internet) .

Mobile:  Mobile VPN waa shabakad ay aaladaha mobiladu galaan Shabakadda Gaarka ah ee Virtual^{(Virtual Private Network)} ( VPN ) ama intranetka marka ay ka guurayaan meel kale.

Hardware:  Hardware VPN waa hal, qalab gooni u taagan. Hardware VPN^{(Hardware VPNs)} -yada waxay bixiyaan ammaan la xoojiyey si la mid ah sida qalabka router-ku u bixiyo guriga iyo kombayutarada ganacsiga yar yar.

VPN s lagama isticmaalo Android oo keliya . Waxaad ka isticmaali kartaa VPN daaqadaha, Linux , Unix iyo wixii la mid ah.

Sidee VPN u shaqeeyaa?^{(How Does VPN work?)}

Way ku caawin lahayd haddii aad ku haysato bixiye VPN qalabkaaga si aad u isticmaasho VPN , hadday tahay telefoonka gacanta ama laptop-ka ama miiska. Iyada oo ku xidhan adeeg bixiyaha, ama waxaad samayn kartaa VPN gacanta ama waxaad ku isticmaali kartaa barnaamij/app kasta. Ku saabsan VPN app, waxaa jira dhowr doorasho oo halkaas ka jira. Waxaad isticmaali kartaa VPN app kasta. Marka VPN lagu rakibo qalabkaaga, dhammaan waxaad diyaar u tahay inaad isticmaasho.

Hadda ka hor intaadan isticmaalin internetka^(Internet) , ku xidh VPN^(VPN) kaaga . Qalabkaagu hadda waxa uu xidhiidh qarsoodi ah la samayn doonaa server-ka VPN ee dalka aad dooran doonto. Hadda kombuyuutarkaaga ama taleefankaaga gacanta ayaa ku shaqayn doona isla shabakad maxalli ah oo la mid ah VPN .

Dhammaan xogta waa la sir ah ka hor inta aysan gaarin shirkadda taleefanka ama bixiyaha WiFi . Hadda wax kasta oo aad isticmaasho internetka, dhammaan taraafikada shabakadaada ka hor inta aanad gaadhin shirkadda telefoonka ama modem ama bixiyaha WiFi waxay gaadhaan shabakad ^(WiFi)VPN oo ammaan ah sida xogta sir ah. Hadda waxay imaan doontaa shirkadda taleefanka ama modem ama WiFi ka dibna ugu dambeyntii server-ka. Markaad raadinayso ciwaanka IP-ga, webserver-ku wuxuu helayaa ciwaanka IP-ga ee  VPN halkii uu ka heli lahaa ciwaanka IP-ga halka laga codsaday. Sidan, VPN waxay kaa caawinaysaa qarinta goobtaada^{(In this way, VPN helps in hiding your location)} . Marka xogtu soo noqoto, waxay markii hore ku gaadhay VPN shirkad telefoon ama WiFiama modem ka dibna nagu soo gaadhay xidhiidh sugan oo sir ah oo VPN ah .

Maaddaama goobta loo socdo ay u aragto server-ka VPN inuu yahay asalka oo uusan ahayn kaaga iyo haddii qof doonayo inuu arko xogta aad direyso, waxay arki karaan oo keliya xogta sir ah ee ma arki karaan xogta ceeriin si VPN ay uga ilaaliso daadinta xogta gaarka ah^{(that VPN protects from leaking of private data)} .

Goobta loo socdo waxay arkaysaa ciwaanka IP-ga ee server-ka VPN oo keliya ee maaha kaaga. Markaa haddii aad rabto inaad gasho qaar ka mid ah bogga la xidhay, waxaad dooran kartaa cinwaanka IP-ga ee VPN server-ka maadaama uu ka yimid meel kale si marka server-ka shabakadu uu ka raadiyo ciwaanka IP-ga halka uu ka soo jeedo, ma heli doono ciwaanka IP-ga oo xannibaya oo awoodi kara. si fudud u dir xogta la codsaday. Tusaale ahaan: Haddii aad ku sugan tahay waddan kale oo aad rabto inaad gasho qaar ka mid ah India n site sida Netflix , kaas oo laga xannibay dalal kale. Markaa waxaad dooran kartaa waddankaaga server-ka VPN sida Hindiya^(India) si marka server-ka Netflix uu u raadiyo ciwaanka IP-ga halka uu codsigu ka yimid, wuxuu heli doonaa ciwaanka IP-gaHindiya^(India) oo si fudud u dir xogta la codsaday. Sidan, VPN waxay ka caawisaa gelitaanka goobaha la xannibay iyo kuwa xaddidan^{(In this way, VPN helps in accessing blocked and restricted sites)} .

Waxaa jira hal faa'iido oo kale oo isticmaalka VPN ah . Qaar ka mid ah qiimayaasha bogagga internetka way kala duwan yihiin iyadoo loo eegayo goobtaada. Tusaale ahaan: haddii aad joogtid Hindiya^(India) , qiimaha shay waa ka duwan yahay, haddii aad joogtid USA , wax la mid ah ayaa ka duwan. Markaa ku xidhidhiyaha VPN wadan uu qiimuhu hooseeyo waxay ka caawisaa inay alaabta ku iibsadaan qiimo jaban waxayna kaydisaa lacag.

Marka, had iyo jeer waxaa lagugula talinayaa inaad ku xirto VPN ka hor inta aanad ku xidhin WiFi dadweynaha , ama haddii aad rabto inaad gasho goobo xanniban ama aad wax ka iibsato internetka ama ballan kasta.

Sida VPN uu u galo mareegaha la xidhay^{(How a VPN gets access to the blocked websites)}

Mareegaha waxaa xannibay Bixiyeyaasha Adeegga Internetka^{(Internet Service Providers)} ( ISP 's) ama maamulayaasha shabakadaha. Marka adeegsaduhu rabo inuu galo degel ay ISP -du xannibto, ISP -gu ma oggola codsiga inuu u socdo server-ka martigelinaya degelkaas. Markaa sida VPN uu u soo maro.

VPN - ku waxa uu ku xidhaa Server-ka gaarka ah ee^{(Private Server)} Virtual ( VPS ), marka marka adeegsaduhu uu codsanayo website-ka, ISP- ka ama router-ka aanu ku xidhanahay waxa aanu u malaynayaa in aanu codsanayno in lagu xidho VPS - ka oo aan la xidhin. Maaddaama ay tani tahay xabo, ISP 's waxay noo ogolaataa inaan galno VPS -kan oo aan ku xidhno iyaga. VPS -yadani waxay codsi u diraan server-ka martigelinaya mareegahan, ka dibna VPS -kan waxay soo celiyaan xogta isticmaalaha. Sidan oo kale, VPN waxay geli kartaa degel kasta.

VPN lacag la'aan ah vs VPN lacag la'aan ah^{(Free VPN vs Paid VPN)}

Haddii aad rabto inaad isticmaasho VPN bilaash ah , waxaad filan kartaa in sirtaada la ilaalin doono ilaa heer, laakiin qaar tanaasulaad ah ayaa la samayn doonaa. Waxaa laga yaabaa inay macluumaadkaaga ka iibinayaan qolo saddexaad ama waxay muujinayaan xayeysiisyo xanaaq badan oo aan loo baahnayn si isdaba joog ah; sidoo kale, waxay diiwaan gelinayaan hawshaada. Waxaa intaa dheer, qaar ka mid ah barnaamijyada VPN^(VPN) ee aan la isku halleyn karin ayaa isticmaalaya macluumaadka si ay u jabsadaan sirta isticmaalaha.

Waxaa lagula talinayaa in aad aado noocyada lacag-bixinta ee VPN -yada maadaama aysan ahayn kuwo aad qaali u ah oo lagu daray waxay ku siin doonaan sir badan oo ka badan kan nooca bilaashka ah. Sidoo kale marka aad isticmaalayso VPN lacag la’aana waxa aad gelaysaa server-ka dadweynaha ama la isticmaalo, hadii aad adeeg VPN lacag ah aad u tagto waxa aad helaysaa server-ka naftada ah, kaas oo kuu horseedaya xawaare fiican. Qaar ka mid ah VPN^(VPN) -yada ugu mushaarka badan waa Express VPN , Nord VPN , Hotspot Shield iyo qaar kaloo badan. Si aad u hubiso qaar la yaab leh oo VPN -yada la bixiyo iyo wax ku saabsan qiimahooda is-diiwaangelinta bilaha iyo sannadlaha ah, eeg maqaalkan.^{(check out this article.)}

Khasaaraha isticmaalka VPN^{(Disadvantages of Using a VPN)}

• Xawaaruhu waa arin weyn marka la isticmaalayo VPN .
• Ku lug lahaanshaha VPS waxay kordhisaa dhererka habka soo qaadashada bogga internetka oo sidaas darteed hoos u dhigida xawaaraha.
• Xidhiidhada VPN^(VPN) waxay hoos u dhici karaan si lama filaan ah, waxaana laga yaabaa inaad sii wadato isticmaalka internetka adoon ogayn arrintan.
• Isticmaalka VPN waa sharci-darro dalalka qaarkood maadaama ay bixiyaan qarsoodi, qarsoodi, iyo sir.

What is a VPN and how it works?

You have probably heard of a VPN before, and you have lіkely used it аlso. A VPN stands fоr Virtυal Private Network, whіch basically means it gives yоu privacy onlіne. Originally, only big businesses and government organizations used VPN serviceѕ, but nowadays, many internet users use VPN services to secure their data. Nowadays, everyone uses a VPN since it ensures that your location stays private; the data іs enсrypted while you can surf the internet anonymously.

Today in the world of growing technology, there is no work for which we are not dependent on the Internet. Internet is not only a part of our life these days, in fact, but it is also our life. Without the internet, we feel like nothing exists. But as technology and use of the internet are growing tremendously day by day, it also raises Security’s question. As we do online payments using phones and laptops, we send our personal details to others using social media. Hence, all our phones and laptops contain very sensitive and private information that obviously needs to be protected and secured.

We use the Internet a lot but do not know how does it work. So, let’s look at first how the Internet actually transfers and receive data.

How Internet Works

These days you can access the Internet in several ways. Like in phones, you can use mobile data or any WiFi connection. In laptops or PCs you can use WiFi or lane cables. You may have some modem/router to which your desktop is connected via Ethernet and your laptops and phones through WiFi. Before connecting to the mobile data or modem or WiFi, you are at your local network, but as soon as you connect to any of them, you are at a vast network called the Internet.

Whenever you do something on the Internet like searching for a web page, it first reaches from your local network to phone company or company’s WiFi you are using. From there it heads towards vast network ‘Internet’ and eventually arrives at the webserver. At web server it looks for the web page you have requested and send back the requested web page which flies over the internet and arrives at the phone company and eventually makes it way through modem or mobile data or WiFi (whatever you are using to access the internet) and finally reaches at your computer or phones.

Before sending your request to internet, an address called IP address is attached to it so that when requested web page arrives it should know from where the request was sent and where it has to reach. Now the request we have made travel through the local network, phone company or modem, internet and then finally at the webserver. Hence, our IP address is visible at all these places, and through IP address, anyone can access our location. The web page will also log your IP address due to heavy traffic and temporarily for some time it will be logged there, and here it raises the question of privacy. It can hinder your private data and can look at what you are doing on your systems.

The biggest privacy problem arises with open WiFi. Suppose you are at some restaurant which offers free and open WiFi. Being a desperate internet user, you will immediately connect to it and start using it as much as possible without knowing that most of these free WiFi’s are completely open without any encryption. It is very easy for free WiFi provider to look into your private data and what you are doing. The worst thing is it is also easy for other people connected with the same WiFi hotspot to capture all packets (data or information) send over this network. It makes it very easy for them to pull out all the information regarding your passwords and websites you are accessing. So it is always advised you should not access your sensitive information like banking details, online payments etc. using public open WiFi.

While accessing some sites, one problem arises about that content or site is blocked, and you cannot access it. It can be for an educational reason or political reason or any other reason. For example, Universities provide each student login credentials so that they can access college WiFi. But some sites ( like torrent etc. ), which universities find are not suitable for students, blocked them so that students cannot access them using college WiFi.

So, to solve all these problems, VPN comes into the role.

What is a VPN ??

VPN stands for Virtual Private Network. It creates a safe, secure and encrypted connection to other networks over the less-secure network such as the public Internet. It provides a shield to your local network so that whatever you are doing like browsing websites, accessing sensitive information, etc., will not be visible to other networks. It can also be used to access restricted sites and more.

Initially, VPNs were created to connect business networks and provide business employees inexpensive, safe access to corporate data. Nowadays, VPNs have become very popular. They are used by a large number of people like students, employees, freelancers, and business travellers (who travel in different countries) to access the restricted sites. VPN serves many purposes:

• Protect from leaking of private and sensitive data by providing security
• Helps in accessing blocked and restricted sites
• Protect from being logged by a web server during heavy traffic
• Helps in hiding the true location

Types of VPN

There are several types of VPN:

Remote Access: A Remote Access VPN allows an individual user to connect to a private business network by providing location as a remote location using a computer or laptop connected to the Internet.

Site-to-site: Site to Site VPN allows multiple offices at a fixed location to connect over a public network such as the Internet.

Mobile: Mobile VPN is a network in which mobile devices access a Virtual Private Network (VPN) or intranet while moving from one location to another.

Hardware: Hardware VPN is a single, stand-alone device. Hardware VPNs provide enhanced security in the same way as hardware routers provide for home and small-business computers.

VPNs are not used only from Android. You can use VPN from windows, Linux, Unix and so on.

How Does VPN work?

It would help if you had a VPN provider in your device to use VPN, whether it is a mobile phone or laptop or desktop. Depending on the service provider, you can either set up the VPN manually or use it through any programme/app. Regarding VPN app, there are several choices out there. You can use any VPN app. Once the VPN is set up in your device, you are all set to use it.

Now before using the Internet, connect your VPN. Your device will now make an encrypted connection to the VPN server in the country you will choose. Now your computer or mobile phone will act on the same local network as a VPN.

All the data is encrypted before it reaches to phone company or WiFi provider. Now whatever you do use the internet, all your network traffic before reaching the phone company or modem or WiFi provider reaches a secure VPN network as encrypted data. Now it will arrive at the phone company or modem or WiFi and then finally at the webserver. When looking for an IP address, the webserver gets the IP address of  VPN instead of the IP address from where the request was made. In this way, VPN helps in hiding your location. When data comes back, it first reached VPN through phone company or WiFi or modem and then reached to us through a secured and encrypted connection of VPN.

As destination site sees VPN server as the origin and not yours and if someone wants to see what data you are sending, they can only see the encrypted data and not the raw data so that VPN protects from leaking of private data.

The destination site sees the IP address of VPN server only and not yours. So if you want to access some blocked site, you can choose VPN server IP address as it is from somewhere else so that when web server looks for IP address of from where the request is originated, it will not find the IP address block and can easily send the requested data. For example: If you are in a different country and want to access some Indian site like Netflix, which is blocked in other countries. So you can choose your VPN server country like India so that when the Netflix server looks for IP address from where the request originated, it will find the IP address of India and easily send the requested data. In this way, VPN helps in accessing blocked and restricted sites.

There is one more benefit of using a VPN. Some online sites prices vary according to your location. Example: if you are in India, the price of something is different, and if you are in the USA, the same thing is different. So connecting VPN to a country where prices are low helps buy the product at low prices and saves money.

So, it is always advisable to connect to VPN before connecting to public WiFi, or if you want to access blocked sites or do online shopping or any booking.

How a VPN gets access to the blocked websites

Websites are blocked by our Internet Service Providers (ISP’s) or by the network administrators. When a user wants to access a website that the ISP blocks, the ISP does not allow the request to move forward to the server hosting that website. So how a VPN gets through it.

A VPN connects to a Virtual Private Server (VPS), so when the user is requesting a website, the ISP or the router to which we are connected to think that we are requesting to be connected to the VPS which is not blocked. As this is a spoof, the ISP’s allow us access to these VPS and connect to them. These VPS send a request to the server that are hosting these websites, and then these VPS returns the user’s data. In this way, VPN’s get access to any website.

Free VPN vs Paid VPN

If you are going to use a free VPN, you can expect that your privacy will be maintained up to some level, but some compromises will be made. They may be selling your information to a third party or showing irritating and unnecessary ads repeatedly; also, they are logging your activity. Moreover, some unreliable VPN apps are using the information to hack into user privacy.

It is advised to go for paid versions of VPN’s as they are not very costly plus they will provide you with a lot more privacy than the free version would. Also, when using a free VPN, you will get access to a public or used server, and if you go for a VPN service that is paid, you will get a server for yourself, which will lead to a good speed. Some of the best paid VPN’s are Express VPN, Nord VPN, Hotspot Shield and many more. To check out some amazing paid VPN’s and about their monthly and yearly subscription rate, check out this article.

Disadvantages of Using a VPN

• The speed is a big issue when using a VPN.
• The involvement of VPS increases the process length of fetching a webpage and thus decreases the speed.
• VPN connections can drop unexpectedly, and you might keep using the internet without knowing about this.
• The use of VPN is illegal in some countries as they provide anonymity, privacy, and encryption.
• Some online services can detect the presence of a VPN, and they block the VPN users.

VPN’s are great for providing privacy and encryption of your data from anyone interested in viewing your data illegally. One can use them to unblock sites and maintain privacy. However, VPN’s are not needed every time. If you are connected to a public WiFi, it is recommended to use a VPN to protect your information from getting hacked.
