- Iran's National Information Network (NIN) is a state-controlled intranet designed to function independently of the global internet.
- The NIN enables selective blackouts, allowing domestic services to run while blocking international platforms.
- Iran's Great Firewall (IRGFW) filters, blocks, and surveils traffic, but has vulnerabilities due to outdated IP records.
- Pingtunnel uses ICMP packets to bypass censorship, allowing slow but functional communication.
- Starlink terminals bypass local ISP infrastructure, with users sharing connections via WireGuard VPN tunnels.
- Self-hosted encrypted services like Matrix Synapse can operate within the NIN, providing secure local communication.
