AS49867Shuji Ito
As of 26th September 2026, AS49867 (Shuji Ito), a network registered in Canada with APNIC, originates 1 IPv4 prefix covering 256 addresses and 8 IPv6 prefixes. By IPv4 address space that makes it the 59,122nd-largest of the 79,516 networks we see originating IPv4, and the 1,150th-largest of 1,575 in Canada. It is seen behind 4 upstream networks, most often AS63798 (Industrial Cyber Security Center of…) and AS38074 (SDCC Japan-West Area). 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 AS49867 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS49867 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.
