As of 10th November 2026, AS999 (CORIX NETWORKS), a network registered in the United States with ARIN, originates 6 IPv4 prefixes covering 1.5k addresses and 17 IPv6 prefixes. By IPv4 address space that makes it the 31,734th-largest of the 80,733 networks we see originating IPv4, and the 7,207th-largest of 18,751 in the United States. It is seen behind 18 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS6453 (TATA Communications (America) Inc), and in front of 27 downstream networks. 9% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 78% of its routes reach at least 90% of full-feed peers, and 4 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.
