AS139137Chinese Academy of Telecommunication Research
ChinaRegistryAPNICAs of 10th November 2026, AS139137 (Chinese Academy of Telecommunication…), a network registered in China with APNIC, originates 1 IPv4 prefix covering 256 addresses. By IPv4 address space that makes it the 59,962nd-largest of the 80,733 networks we see originating IPv4, and the 531st-largest of 617 in China. It is seen behind 1 upstream network, most often AS9808 (China Mobile Backbone). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 0% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS139137 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS139137 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.
