ChinaRegistryAPNIC

As of 27th September 2026, AS38283 (CHINANET SiChuan Telecom Internet Data…), a network registered in China with APNIC, originates 524 IPv4 prefixes covering 351k addresses and 54 IPv6 prefixes. By IPv4 address space that makes it the 878th-largest of the 79,536 networks we see originating IPv4, and the 63rd-largest of 607 in China. It is seen behind 1 upstream network, most often AS4134 (China Telecom Backbone), and in front of 8 downstream networks. Over 99% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS38283 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.
