VPN is used in the website of studies like - school or college website, large company etc. You can use VPN in both mobile computers.

How VPN works:

An IP address is assigned to the internet that you use on your mobile or computer. IP address can detect the location of your device. As soon as you open any website in the browser, the request reaches the server of that website with your IP address.

Similarly, that server detects the location of your device. After verifying the IP, the server sends its data to your device. Now there is no security in this connection. VPN secures all the work you do on the Internet.

Using VPN, you can also access the restriction on the Internet, which means that you can access the website that you did not get permission to view or that website has been blocked by your country. There are two technologies through which the VPN connection can be connected so that the data is transmitted securely over the public network.

By Tunneling:- Tunneling means creating a tunnel on the public network, in which the whole packet is transmitted to the public network in another packet. In this, encapsulating protocols are chosen so that when the data is transmitted over the public network, other computers or network devices can not understand it. By encryption we can scramble the data so that only he can understand the receiver.

By Encryption:- The tunneling is meant to create a tunnel on the public network in which the whole packet is transmitted to the public network in other packets. In this, the encapsulating protocol is chosen in such a way that other computers or network devices can not understand it while transmitting data to the public network.

VPN Network Protocol:

Over time, some protocols and security features are also increasing; some of these protocols are as follows:

1. IP security: It is often used to secure the internet connection.

2. PPTP: Point-to-Point Tunneling Protocol is a technology used to create VPN. PPTP is from windows 95 The special thing of PPTP is that it is easily set up with every major operating system, but just a few moments ago, a lot of questions were raised about the security of PPTP. PPTP is still strong but not completely secure. It does not encrypt, but it only tunnels and encrypts the data packets.

3. L2TP: Layer 2 Tunneling Protocol is a technology that is an extension of PPP protocol that enables ISP to operate VPN.

4. SSL (Secure Sockets Layer) and TLS (Transport Layer Security): SSL and TLS create a VPN connection where the web browser works as a client and users have access to specific applications rather than access to the entire network . SSL and TLS protocols are used by most online shopping websites and service providers.

5. SSH (Secure Shell): SSH is also known as Secure Socket Shell. This is a network protocol by which administrators can secure access to remote computers. Secure Shell makes strict authentication and encrypted data communication between two computers on an insecure network like the Internet.

6. Open VPN: Open VPN is an SSL based VPN that is becoming very popular. This software is freely available, SSL is a mature encription protocol and Open VPN can be run on a single UDP YA TCP port, which makes it very flexible.
7. L2TP / IP Sec: L2TP / IP is more secure than PPPTP. L2TP / IPSec applies two protocols together to provide the best features in which the L2TP tunnel creates and IPSec provides a secure channel.

How To Change Location In Mobile By Using VPN:

It is very easy to change your location from VPN in your mobile so you will find a lot of applications on the internet which helps you to change your internet location.

Installation of VPN is a straightforward process. It is often as easy as entering a username and server address. The major smartphones can configure VPNs using PPP and L2TP / IPsec protocols. All major operating systems can configure PPTP VPN connections. OpenVPN and L2TP / IPsec protocols require downloading a small open source application (OpenVPN) and certificate, respectively.

VPN type:
VPN is mainly of three types - Site-to-Site VPN, PPTP VPN, IPsec.

1. Site-to-Site VPN: While using this VPN, it can not use any dedicated line in it. In it, different sites of the same organization, each one has its own network, connect together to create a VPN. The site-to-site VPN is almost the same as PPTP, leaving only one thing. Unlike PPTP, routing, encryption and decryption are both built in the router at the end, which can be based on a hardware or software.

2.PPTP VPN: PPTP stands for Point-to-Point Tunneling Protocol. This is a very common and widely used VPN protocol. Its disadvantage is that it does not provide encryption and in this, users connect to a VPN network using the password authentication on the VPN on the current Internet connection. This does not require additional hardware and its features are often available as a cheap add-on software.

3. IPsec VPN: This is a trusted protocol that sets up a tunnel on a central site from a remote site. As its name suggests that it has been designed for IP traffic. IPSec requires expensive, time-consuming client installations and this is why it is considered as the largest dissevantage.
