ChinaRegistryAPNICTypeCarrier

As of 26th September 2026, AS23911 (China Next Generation Internet Beijing…), a transit carrier registered in China with APNIC, originates 2 IPv4 prefixes covering 512 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 48,547th-largest of the 79,480 networks we see originating IPv4, and the 485th-largest of 607 in China. It is seen behind 11 upstream networks, most often AS3491 (PCCW Global (HK) Ltd.) and AS6939 (Hurricane Electric LLC), and in front of 6 downstream networks. None of its announcements have a valid RPKI ROA. 0% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS23911 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.
