ChinaRegistryAPNICTypeEyeball

As of 27th September 2026, AS17622 (China Unicom Guangdong Province Network), an access network registered in China with APNIC, originates 467 IPv4 prefixes covering 1.2M addresses and 1,977 IPv6 prefixes. By IPv4 address space that makes it the 403rd-largest of the 79,523 networks we see originating IPv4, and the 31st-largest of 607 in China. It is seen behind 2 upstream networks, most often AS4837 (China Unicom Backbone) and AS9929 (China Unicom Industrial Internet…), and in front of 4 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 9 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS17622 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.
