ChinaRegistryAPNICTypeEyeball

As of 26th September 2026, AS23724 (China Telecom Beijing IDC Network), an access network registered in China with APNIC, originates 818 IPv4 prefixes covering 3.3M addresses and 89 IPv6 prefixes. By IPv4 address space that makes it the 187th-largest of the 79,480 networks we see originating IPv4, and the 17th-largest of 607 in China. It is seen behind 1 upstream network, most often AS4134 (China Telecom Backbone), and in front of 13 downstream networks. 88% of its announcements have a valid RPKI ROA; 2 are RPKI-invalid. 73% of its routes reach at least 90% of full-feed peers, and 241 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS23724 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.
