How VPN works

Most people use VPN in 2 ways – (Virtual private network)First, by installing Apps in their Smartphone.
Second – by adding extensions to the browser.

When we connect our Smartphone or our Browser to VPN. And then when we try to visit a website, first our request goes to the server of that VPN and then from that server to another website that we wanted to visit.

In this way our ISP (Internet Service Provider) is not able to know which website we have visited because all they know is that we are just visiting the server of that VPN and not any Block Website. To.

When we reach the VPN server, the VPN server knows which website we want to visit and sends it to that website.

Since there is no site block in the country where it is VPN, which we want to visit, then we get that site easily.

And in this way we visit that block website with the help of VPN without informing the ISP (Internet Service Provider).
But the thing to know is how ISPs block a site. Let’s know

How ISP Block Websites: How ISP blocks a website

Full form of ISP = Internet Service Provider
ISP Full Form = Internet Service Provider

When we try to visit a site, first the address of that site goes to our ISP and if the ISP has to block that site, then they do not give way to the server IP of that site in front of the ISP Broadband gives the IP of the Router or its own server in front of the address of its site.

With which our request never reaches the server of that site, and remains on our ISP’s server, from which that site is considered as Ban or Block by ISP.

Let us understand by example, which will make us understand more.

Suppose the ISP has to ban or block Google.com in India on the orders of the Government of India.
Now, whenever we enter Google.com in our browser, then the request before our device (Mobile, Tablet or Computer) will go to our ISP (BSNL, Jio, Airtel, Vodafone) that we will use Google.com (whose service IP is 216.48.216.164), but this address has been banned by ISP. ISP will never send your request to Google’s server and you will not be able to visit this site.

How to Unblock VPN Websites

VPN does not unblock sites but bypass that security. But let’s understand how it does.
After ‘ON’ VPN, when we request to visit any Block Sites, then that VPN shows its VPN Server IP by not showing the address (Server IP) of that site and ISP thinks it If we just want to visit the server of that VPN, then the ISP gives us a way to go ahead.

When our request reaches VPN server, VPN forward that request to our site (which we were trying to visit) and then take the information from there and come to our VPN server and then the VPN server should have that information The server comes to us with the help of IP.

In this entire sequence, the ISP (Internet Service Provider) feels that we are taking information from that VPN server
And that VPN server is not banned, in this way we use Block Sites with the help of VPN.
