Further Notes
Blocking a website, URL or IP associated with VPN services is the first line of defense by government authorities to prevent a population from accessing the internet outside of their usual jurisdiction. While it makes surveillance and intrusion of privacy more difficult, perhaps the most common reason to prevent VPN use is simply to keep banned or restricted websites out of internet users reach.
Furthermore at least China and Iran are known to practice “VPN Blocking” which is a technique to block communication protocols between encrypted tunnels that communicate between user and server side.
