As of 28th September 2026, AS855 (Bell Canada), an access network registered in Canada with ARIN, originates 829 IPv4 prefixes covering 1.7M addresses and 6 IPv6 prefixes. By IPv4 address space that makes it the 308th-largest of the 79,556 networks we see originating IPv4, and the 7th-largest of 1,575 in Canada. It is seen behind 5 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS3356 (Lumen (Level 3)), and in front of 29 downstream networks. 94% of its announcements have 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 AS855 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.
