AS63561China Electronics Technology Cyber Security Co.,LTD
As of 12th November 2026, AS63561 (China Electronics Technology Cyber…), a network registered in China with APNIC, originates 2 IPv4 prefixes covering 2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 25,873rd-largest of the 80,772 networks we see originating IPv4, and the 357th-largest of 618 in China. It is seen behind 2 upstream networks, most often AS38283 (CHINANET SiChuan Telecom Internet Data…) and AS9808 (China Mobile Backbone). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 67% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS63561 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS63561 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.
