ChinaRegistryAPNIC

As of 27th September 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 2,147th-largest of the 79,523 networks we see originating IPv4, and the 119th-largest of 607 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.

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.
