Discover how VPNs can be blocked and what you can do about it
Greetings, fellow internet users! We all love the feeling of being able to browse the web without restrictions. However, some websites limit our access, and some countries censor the internet. A feasible solution for this is using a Virtual Private Network (VPN). But can a VPN be blocked? In this article, we will discuss the truth about VPN blockage and what you can do about it.
Introduction
A VPN is an excellent tool that encrypts your internet traffic and masks your IP address. It allows you to access geo-restricted content, bypass censorship, and enhances your online privacy. Nevertheless, some websites and services are starting to block VPN connections. It is a growing concern for internet users who rely on VPN technology to access blocked websites or protect their online privacy.
In this article, we will explore the topic of VPN blocking and its implications. We will also look at the advantages and disadvantages of VPNs and provide answers to frequently asked questions. Finally, we will provide some tips that can help you prevent VPN blockage and stay secure online.
Can a VPN be Blocked?
The simple answer is yes, a VPN can be blocked. However, it is not an easy task, and it requires a lot of effort on the part of the website or service doing the blocking. VPN blockage usually involves detecting and blocking the IP addresses used by the VPN providers. It is known as IP blocking. Another method is Deep Packet Inspection (DPI), which involves inspecting the data packets being transmitted and blocking those belonging to VPN connections.
VPN blockage is a significant concern for internet users who rely on VPN technology. Netflix, Hulu, and Amazon Prime Video have started to block VPN connections from accessing their services. Some countries also block VPNs to prevent their citizens from accessing restricted content. In China, the Great Firewall blocks most VPN connections.
However, VPN providers are continually working on ways to bypass these blocks. It is a game of cat and mouse. As soon as a VPN provider finds a way to bypass the block, the website or service doing the blocking finds a way to block it again. It is an ongoing battle that shows no signs of slowing down.
How are VPNs Blocked?
VPN blockage involves different methods, and the most common ones are IP blocking and DPI. In IP blocking, websites or services block the IP addresses used by VPN providers. They create a list of these addresses and block them from accessing their services. If you use a VPN server with a blocked IP address, you will not be able to access the service. Some websites and services also block entire data centers used by VPN providers.
DPI involves inspecting the data packets being transmitted and blocking those belonging to VPN connections. DPI can detect the use of VPNs, and it can also detect the type of VPN being used. DPI can also block specific ports commonly used by VPNs.
Another way VPNs can be blocked is by DNS blocking. In DNS blocking, the website or service blocks the DNS requests originating from VPN connections. This method is not very effective since VPN providers can use alternative DNS servers.
