While Netflix is available in 190+ countries, the content library varies dramatically. Some countries block Netflix entirely. A VPN lets you access any Netflix library in the world.
Netflix is blocked in China, North Korea, Crimea, Syria. The blocks operate at the network layer — typically a combination of DNS poisoning, IP filtering, and SNI inspection. Domestic ISPs in restricted countries are required to drop traffic to Netflix's domains and origin servers, which is why typing the address into a browser returns a connection failure rather than a clean error message.
A VPN bypasses all three filtering methods at once. GhostShield's WireGuard tunnel encrypts every packet end-to-end, so ISPs see only encrypted traffic to a single GhostShield server IP. DNS resolves through our infrastructure, not the local ISP's. The TLS handshake happens between you and the GhostShield server — never directly to Netflix's domains — so SNI inspection finds nothing to block. Netflix itself sees a connection from a country where it operates normally and serves you the standard experience.
