AS4847China Telecom Beijing Province Network
As of 11th November 2026, AS4847 (China Telecom Beijing Province Network), an access network registered in China with APNIC, originates 910 IPv4 prefixes covering 4.8M addresses and 17 IPv6 prefixes. By IPv4 address space that makes it the 140th-largest of the 80,747 networks we see originating IPv4, and the 11th-largest of 617 in China. It is seen behind 2 upstream networks, most often AS4134 (China Telecom Backbone) and AS4809 (China Telecom Next Generation Carrier…), and in front of 62 downstream networks. 84% of its announcements have a valid RPKI ROA; 42 are RPKI-invalid. 76% of its routes reach at least 90% of full-feed peers, and 136 prefixes are also originated by another network.

Upstream graph
The networks AS4847 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS4847 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.
