This message indicates that Netflix has detected the use of a Virtual Private Network (VPN) or proxy server. The system recognizes the internet traffic as originating from a shared or obscured IP address, rather than a typical residential or mobile connection. For example, a user connecting through a commercial VPN service to bypass geographical restrictions might encounter this message.
The implementation of this detection mechanism aims to enforce content licensing agreements, which are often geographically specific. Content distributors grant Netflix rights to stream television shows and movies only within particular regions. By preventing VPN and proxy usage, Netflix protects these contractual obligations and avoids potential legal issues related to unauthorized content distribution. Historically, this practice has become more prevalent as VPN technology has become increasingly accessible, making geographical content restriction circumvention more common.
