AS38365Beijing Baidu Netcom Science and Technology Co., Ltd.
As of 11th November 2026, AS38365 (Beijing Baidu Netcom Science and…), a content network registered in China with APNIC, originates 124 IPv4 prefixes covering 620k addresses and 12 IPv6 prefixes. By IPv4 address space that makes it the 630th-largest of the 80,743 networks we see originating IPv4, and the 49th-largest of 617 in China. It is seen behind 6 upstream networks, most often AS58466 (CHINANET Guangdong province network) and AS23724 (China Telecom Beijing IDC Network). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 96% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS38365 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS38365 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.
