TaiwanRegistryAPNICTypeEyeball

As of 11th November 2026, AS24158 (Taiwan Mobile Co., Ltd.), an access network registered in Taiwan with APNIC, originates 553 IPv4 prefixes covering 550k addresses and 510 IPv6 prefixes. By IPv4 address space that makes it the 686th-largest of the 80,747 networks we see originating IPv4, and the 20th-largest of 241 in Taiwan. It is seen behind 1 upstream network, most often AS9924 (Taiwan Fixed Network, Telco and Network…), and in front of 3 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS24158 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.
