ISP stands for Internet Service Provider. It is an organization which provides internet services to the customers in homes and workplaces. ISP allows you to explore and use the internet. The ISP connects the server you are using to the servers all across the internet. Basically it acts as a channel between your PC and other servers.
When a user sends a request to the server, the request is first sent to the ISP servers and then it is forwarded to its destination point via other servers. ISP provides Internet services to the customers through dioptric, space stations, or copper cables.
What is a VPN?
VPN stands for Virtual Private Network. Nowadays people are concerned about their privacy over the internet. VPN provides a service that maintains the privacy and protection of user’s data and activity over the internet. VPN connects you to the public internet services through an encrypted tunnel which ensures that all the actions performed by the user cannot be traced.
The VPN server hides the users’ IP addresses from the public internet and makes all the actions performed by the user totally anonymous. It makes public browsing more secure and reliable. Therefore it reduces the chances of cybercrime, data theft, and other means of misusing the personal information of any user.
How Does VPN Work?
First, the user shall install any software which provides VPN services.
- The VPN software will encrypt the data sent from the clients’ server and send it to the VPN server through a secure connection.
- The VPN server decrypts the data and sends it to the internet.
- The VPN server once again encrypts the data received from the internet and sends it to the clients’ server.
- The data is decrypted by the VPN software so that it can be meaningful to the user.
Can ISP See And Block VPN?
Yes, ISP can see if a person is accessing the internet through a VPN.
The data is sent from the clients’ server to its destination through ISP. The only way this is possible is if the ISP knows where to send the data. The destination point for the data would be a VPN server if the user is using a VPN. Hence the ISP can see the amount of data being passed and also the users’ IP address despite the fact that the data is encrypted.
But ISP cannot see the actions you perform online when you are connected to a VPN. For example, they can know if you have accessed Facebook, but they cannot know what you are doing with it. VPN encrypts all the data, which stops ISP from accessing or using your personal information and online activities.
If TCP protocol is used with port 443 in OpenVPN, then ISP will only be able to see the secured websites you are visiting such as Google, Gmail, and Facebook, etc.
