As of 26th September 2026, AS38676 (flexnetworks), an access network registered in South Korea with APNIC, originates 209 IPv4 prefixes covering 103k addresses. By IPv4 address space that makes it the 2,332nd-largest of the 79,516 networks we see originating IPv4, and the 69th-largest of 908 in South Korea. It is seen behind 3 upstream networks, most often AS9457 (DREAMLINE CO.) and AS4766 (Korea Telecom). None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS38676 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.
