South KoreaRegistryAPNICTypeContent

As of 26th September 2026, AS135120 (PROJECT ELIV), a content network registered in South Korea with APNIC, originates 46 IPv4 prefixes covering 13.8k addresses and 8 IPv6 prefixes. By IPv4 address space that makes it the 8,836th-largest of the 79,516 networks we see originating IPv4, and the 194th-largest of 908 in South Korea. It is seen behind 4 upstream networks, most often AS137409 (GSL Networks Pty LTD) and AS199524 (Gcore S.A.), and in front of 7 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% 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 AS135120 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.
