AS24163UNION BROADBAND NETWORK
TaiwanRegistryAPNICTypeEyeballAs of 10th November 2026, AS24163 (UNION BROADBAND NETWORK), an access network registered in Taiwan with APNIC, originates 62 IPv4 prefixes covering 66k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 3,521st-largest of the 80,733 networks we see originating IPv4, and the 43rd-largest of 241 in Taiwan. It is seen behind 1 upstream network, most often AS9924 (Taiwan Fixed Network, Telco and Network…). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 95% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Upstream graph
The networks AS24163 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS24163 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.
