AS134543China Unicom Guangdong IP network
As of 11th November 2026, AS134543 (China Unicom Guangdong IP network), an access network registered in China with APNIC, originates 175 IPv4 prefixes covering 78.3k addresses and 626 IPv6 prefixes. By IPv4 address space that makes it the 2,873rd-largest of the 80,747 networks we see originating IPv4, and the 142nd-largest of 617 in China. It is seen behind 1 upstream network, most often AS4837 (China Unicom Backbone). Over 99% of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers, and 11 prefixes are also originated by another network.

Upstream graph
The networks AS134543 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS134543 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.
