As of 10th November 2026, AS1403 (EBOX), an access network registered in Canada with ARIN, originates 240 IPv4 prefixes covering 552k addresses and 20 IPv6 prefixes. By IPv4 address space that makes it the 682nd-largest of the 80,723 networks we see originating IPv4, and the 17th-largest of 1,605 in Canada. It is seen behind 8 upstream networks, most often AS577 (Bell Canada) and AS6939 (Hurricane Electric LLC), and in front of 105 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS1403 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.
