As of 14th November 2026, AS55392 (INTERNET MULTIFEED CO.), an access network registered in Japan with APNIC, originates 5 IPv4 prefixes covering 67.6k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 3,319th-largest of the 80,844 networks we see originating IPv4, and the 129th-largest of 737 in Japan. It is seen behind 3 upstream networks, most often AS2497 (Internet Initiative Japan Inc.) and AS6939 (Hurricane Electric LLC), 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 AS55392 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.
