AS4811China Telecom Shanghai IDC Network
As of 11th November 2026, AS4811 (China Telecom Shanghai IDC Network), a network registered in China with APNIC, originates 1,518 IPv4 prefixes covering 1.2M addresses and 97 IPv6 prefixes. By IPv4 address space that makes it the 417th-largest of the 80,747 networks we see originating IPv4, and the 32nd-largest of 617 in China. It is seen behind 2 upstream networks, most often AS4134 (China Telecom Backbone) and AS4812 (China Telecom Shanghai Province Network), and in front of 12 downstream networks. 99% of its announcements have a valid RPKI ROA; 2 are RPKI-invalid. 85% of its routes reach at least 90% of full-feed peers, and 233 prefixes are also originated by another network.

Upstream graph
The networks AS4811 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS4811 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
