As of 10th November 2026, AS2515 (Japan Network Information Center), an access network registered in Japan with APNIC, originates 4 IPv4 prefixes covering 3.1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 20,470th-largest of the 80,733 networks we see originating IPv4, and the 446th-largest of 737 in Japan. It is seen behind 11 upstream networks, most often AS2518 (BIGLOBE Inc.) and AS2497 (Internet Initiative Japan Inc.), and in front of 1 downstream network. 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.

Networks observed one and two hops upstream of AS2515 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.
