ChinaRegistryAPNICAs of 10th November 2026, AS140886 (UNICOM Guangxi province network), a network registered in China with APNIC, originates 14 IPv4 prefixes covering 8.2k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 12,070th-largest of the 80,733 networks we see originating IPv4, and the 275th-largest of 617 in China. It is seen behind 1 upstream network, most often AS4837 (China Unicom Backbone). 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.

Upstream graph
The networks AS140886 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS140886 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.
