AS22950University of Saskatchewan
CanadaRegistryARINAs of 28th September 2026, AS22950 (University of Saskatchewan), a network registered in Canada with ARIN, originates 12 IPv4 prefixes covering 68.4k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 3,199th-largest of the 79,544 networks we see originating IPv4, and the 95th-largest of 1,575 in Canada. It is seen behind 2 upstream networks, most often AS26806 (SRNet Saskatchewan Research Network Inc.) and AS803 (Saskatchewan Telecommunications), 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.

Upstream graph
The networks AS22950 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS22950 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.
