Here's how your ISP and the entire internet know that you're using a VPN
Virtual Private Networks (VPNs) encrypt traffic and mask a user's IP address, making them popular for privacy, anti‑censorship, and geo‑blocking circumvention. Services detect VPN usage primarily through IP reputation databases and blacklists that identify ranges belonging to VPN providers or data‑center hosts. Companies such as Netflix often block or restrict access when an IP is found on these lists, especially those associated with cloud providers.
- ▪VPNs create an encrypted tunnel that routes traffic through a remote server, hiding the user's real IP address and location.
- ▪Internet services maintain or subscribe to IP reputation databases that flag addresses known to belong to VPN or proxy providers.
- ▪Netflix and similar streaming platforms use these blacklists to identify and block VPN traffic, often targeting data‑center IP ranges.
- ▪Many countries that enforce internet censorship also ban VPN usage to prevent circumvention of their controls.
