National Information Network

The National Information Network (NIN; Persian: شبکۀ ملی اطلاعات, romanized: Shabake-ye Melli-ye Ettelā'āt), also known as National Internet in Iran and the Iranian intranet, is an Iranian ongoing project backed by IRGC to develop a secure, stable, and controlled infrastructure network and national intranet in Iran. The Supreme Council of Cyberspace defines the NIN as "a network based on the Internet Protocol with switches and routers and data centers which allows for data requests to avoid being routed outside of the country and provides secure and private intranet networks." It is a domestic network which connects to the external internet via a government controlled gateway.
