AS134542China Unicom IP network
ChinaRegistryAPNICAs of 11th November 2026, AS134542 (China Unicom IP network), a network registered in China with APNIC, originates 19 IPv4 prefixes covering 119k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 2,178th-largest of the 80,747 networks we see originating IPv4, and the 117th-largest of 617 in China. It is seen behind 1 upstream network, most often AS4837 (China Unicom Backbone), and in front of 1 downstream network. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 50% of its routes reach at least 90% of full-feed peers, and 11 prefixes are also originated by another network.

Upstream graph
The networks AS134542 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS134542 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.
