Stefan Coders The use of virtual private networks (VPNs) to mask users’ browsing activity and the location is currently banned in China. That is because the Chinese government has banned VPNs and VPN servers from public use. The Chinese government currently uses tools like Uniform Resource Locator (URL) filtering to block people from accessing specific websites or keywords. It also deploys tactics like Domain Name System (DNS) poisoning to make websites unavailable to people in the country, as well as methods like port blocking and deep packet inspection that restrict internet activity. To further restrict what people can do online, the Chinese government has ordered its state-run phone networks—China Mobile, China Telecom, and China Unicorn, which have nearly 1.4 billion customers combined—to prevent the operations of organizations that do not have a fixed internet connection.
