JapanRegistryAPNIC

As of 26th September 2026, AS142622 (Dream Information Laboratory), a network registered in Japan with APNIC, originates 26 IPv4 prefixes covering 6.7k addresses. By IPv4 address space that makes it the 13,482nd-largest of the 79,516 networks we see originating IPv4, and the 359th-largest of 729 in Japan. It is seen behind 3 upstream networks, most often AS5065 (Bunny Communications) and AS39600 (BUNNY TECHNOLOGY LLC). 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 AS142622 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.
