V2Ray is a powerful and advanced network tunneling and privacy protection tool, but it is very unfriendly to ordinary users. v2rayN is a popular GUI client for V2Ray on Windows and Linux platforms, developed by 2dust from China.

In order to "help" citizens of many countries bypass a series of restrictions and get in touch with Western media, the US government has provided a lot of funding to many technology companies that provide VPN services through USAGM, including three companies that establish virtual private networks - Psiphon, Lantern, and nthLink. Meanwhile, USAGM is supporting the development of a range of tools to bypass censorships, including VPNs.

An IP address is a unique identification number that is used to identify all computers and websites on the Internet. When you connect to the Internet, your computer is assigned an IP address from your local Internet Service Provider (ISP). This is known as a direct connection to the Internet. But sometimes you need to use a fake IP instead, with the anonymity and privacy security in mind, for example:

• Access some websites banning you or your country IPs
• Surf the Internet anonymously
• Send emails anonymously
• Prevent identity theft and intrusion from hackers
• Prevent anyone from seeing your real IP when communicating with them
