About this network

DCI (DCI-AS), the Information Technology Company of Iran, is a state-run operator that forms the core of Iran's internet, carrying much of the country's consumer traffic.

What it's used for

• Home internet for Iranian consumers and the national data-communications backbone that downstream Iranian ISPs connect through.

Notable

• A large "eyeball" network: addresses here are Iranian end-user connections, commonly behind carrier-grade NAT, not servers.
• State-operated and central to Iran's tightly controlled internet, so it is one of the most-seen origins for Iranian consumer traffic and a common chokepoint during national filtering or shutdowns.
