ChinaRegistryAPNIC

As of 11th November 2026, AS4816 (China Telecom (Group)), a network registered in China with APNIC, originates 47 IPv4 prefixes covering 50.2k addresses and 15 IPv6 prefixes. By IPv4 address space that makes it the 4,505th-largest of the 80,743 networks we see originating IPv4, and the 176th-largest of 617 in China. It is seen behind 1 upstream network, most often AS4134 (China Telecom Backbone), and in front of 1 downstream network. 79% 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 11 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS4816 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.
