As of 10th November 2026, AS812 (Rogers Communications Canada Inc.), an access network registered in Canada with ARIN, originates 1,488 IPv4 prefixes covering 10.2M addresses and 758 IPv6 prefixes. By IPv4 address space that makes it the 70th-largest of the 80,733 networks we see originating IPv4, and the 3rd-largest of 1,606 in Canada. It is seen behind 21 upstream networks, most often AS6461 (Zayo Bandwidth) and AS174 (Cogent Communications, LLC), and in front of 212 downstream networks. 94% of its announcements have a valid RPKI ROA; 6 are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 16 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS812 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.
