JapanRegistryAPNIC

As of 27th September 2026, AS59105 (Home NOC Operators Group), a network registered in Japan with APNIC, originates 5 IPv4 prefixes covering 2.6k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 23,021st-largest of the 79,525 networks we see originating IPv4, and the 451st-largest of 729 in Japan. It is seen behind 11 upstream networks, most often AS2518 (BIGLOBE Inc.) and AS9370 (SAKURA Internet Inc.), and in front of 28 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.

Upstream graph

The networks AS59105 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS59105 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.
