As of 11th November 2026, AS852 (TELUS Communications Inc.), an access network registered in Canada with ARIN, originates 687 IPv4 prefixes covering 5.1M addresses and 30 IPv6 prefixes. By IPv4 address space that makes it the 136th-largest of the 80,743 networks we see originating IPv4, and the 5th-largest of 1,607 in Canada. It is seen behind 21 upstream networks, most often AS2914 (NTT America, Inc.) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 212 downstream networks. 44% of its announcements have a valid RPKI ROA; 3 are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers, and 7 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS852 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.
