As of 22nd October 2026, AS376 (Reseau d'Informations Scientifiques du…), an access network registered in Canada with ARIN, originates 278 IPv4 prefixes covering 1.9M addresses and 10 IPv6 prefixes. By IPv4 address space that makes it the 286th-largest of the 79,663 networks we see originating IPv4, and the 6th-largest of 1,589 in Canada. It is seen behind 13 upstream networks, most often AS6453 (TATA Communications (America) Inc) and AS174 (Cogent Communications, LLC), and in front of 22 downstream networks. 83% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 74% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS376 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.
