South KoreaRegistryAPNIC

As of 10th November 2026, AS4670 (Shinbiro), a network registered in South Korea with APNIC, originates 405 IPv4 prefixes covering 862k addresses. By IPv4 address space that makes it the 521st-largest of the 80,733 networks we see originating IPv4, and the 11th-largest of 915 in South Korea. It is seen behind 2 upstream networks, most often AS9848 (SEJONG NETWORKS) and AS3786 (LG DACOM Corporation), and in front of 5 downstream networks. None of its announcements have a valid RPKI ROA. 88% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS4670 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.
