ChinaRegistryAPNIC

As of 11th November 2026, AS24356 (CERNET2 IX at Chongqing University), a network registered in China with APNIC, originates 75 IPv6 prefixes. It is seen behind 1 upstream network, most often AS23910 (China Next Generation Internet CERNET2). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 5 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS24356 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.
