As of 26th September 2026, AS999 (CORIX NETWORKS), a network registered in the United States with ARIN, originates 6 IPv4 prefixes covering 1.5k addresses and 18 IPv6 prefixes. By IPv4 address space that makes it the 31,099th-largest of the 79,480 networks we see originating IPv4, and the 7,115th-largest of 18,421 in the United States. It is seen behind 18 upstream networks, most often AS6453 (TATA Communications (America) Inc) and AS174 (Cogent Communications, LLC), and in front of 3 downstream networks. 8% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 71% of its routes reach at least 90% of full-feed peers, and 6 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS999 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.
