About this network

China Telecom's ChinaNet backbone (CHINANET-BACKBONE, also called the "163" network) — one of the largest networks on the internet by announced address space.

What it's used for

• Fixed broadband and backbone for hundreds of millions of subscribers across China; a massive "eyeball" network.

Notable

• State-owned; like all Chinese consumer networks, its international traffic passes through the national filtering system (the "Great Firewall").
• Announces one of the biggest IPv4 footprints of any single ASN.

Interesting

• China Telecom also runs CN2 (a higher-quality international backbone, often seen under other ASNs) used for premium cross-border routes.
