JapanRegistryAPNIC

As of 26th September 2026, AS23634 (WIDE Project), a network registered in Japan with APNIC, originates 1 IPv4 prefix covering 256 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 59,122nd-largest of the 79,516 networks we see originating IPv4, and the 639th-largest of 729 in Japan. It is seen behind 5 upstream networks, most often AS7500 (WIDE Project - M-root) and AS2497 (Internet Initiative Japan Inc.). 50% of its announcements have 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 AS23634 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.
