AS17816China Unicom Guangdong Province Network
ChinaRegistryAPNICTypeEyeballAs of 27th September 2026, AS17816 (China Unicom Guangdong Province Network), an access network registered in China with APNIC, originates 117 IPv4 prefixes covering 3.8M addresses and 49 IPv6 prefixes. By IPv4 address space that makes it the 167th-largest of the 79,525 networks we see originating IPv4, and the 14th-largest of 607 in China. It is seen behind 2 upstream networks, most often AS4837 (China Unicom Backbone) and AS9929 (China Unicom Industrial Internet…). 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, and 7 prefixes are also originated by another network.

Upstream graph
The networks AS17816 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS17816 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.
