South KoreaRegistryAPNIC

As of 11th November 2026, AS9957 (KINX), a network registered in South Korea with APNIC, originates 41 IPv4 prefixes covering 14.2k addresses. By IPv4 address space that makes it the 8,943rd-largest of the 80,747 networks we see originating IPv4, and the 196th-largest of 915 in South Korea. It is seen behind 26 upstream networks, most often AS4766 (Korea Telecom) and AS3491 (PCCW Global (HK) Ltd.), and in front of 44 downstream networks. None of its announcements have a valid RPKI ROA. 73% of its routes reach at least 90% of full-feed peers, and 8 prefixes are also originated by another network.

Upstream graph

The networks AS9957 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS9957 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.
