As of 27th September 2026, AS205329 (Kai-Jung Chen), an access network registered in Taiwan with RIPE NCC, originates 2 IPv4 prefixes covering 1k addresses and 10 IPv6 prefixes. By IPv4 address space that makes it the 35,818th-largest of the 79,523 networks we see originating IPv4, and the 136th-largest of 234 in Taiwan. It is seen behind 20 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS134823 (Sky Digital Co., Ltd.), and in front of 4 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 83% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS205329 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.
