ChinaNet

China Telecom's ChinaNet backbone is routed under Autonomous System 4134, one of the largest internet networks in the world by subscriber count. Registered in China, it serves hundreds of millions of residential and enterprise users across the mainland and carries a substantial share of the country's domestic internet traffic. As a state-linked eyeball and backbone network, AS4134 is central to how China connects internally and, through gateway routes, to the global internet. Its scale makes it one of the most populous origin networks worldwide. For geolocation, a matching address generally identifies a subscriber in mainland China served by China Telecom.
