As of 10th November 2026, AS140726 (China Unicom AnHui Province Network), a network registered in China with APNIC, originates 127 IPv4 prefixes covering 150k addresses and 231 IPv6 prefixes. By IPv4 address space that makes it the 1,685th-largest of the 80,723 networks we see originating IPv4, and the 100th-largest of 617 in China. It is seen behind 2 upstream networks, most often AS4837 (China Unicom Backbone) and AS9929 (China Unicom Industrial Internet…), and in front of 3 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS140726 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.
