As of 23rd October 2026, AS35937 (MarquisNet), a network registered in the United States with ARIN, originates 9 IPv4 prefixes covering 12k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 9,608th-largest of the 79,666 networks we see originating IPv4, and the 2,985th-largest of 18,482 in the United States. It is seen behind 3 upstream networks, most often AS6461 (Zayo Bandwidth) and AS3356 (Lumen (Level 3)), and in front of 3 downstream networks. None of its announcements have a valid RPKI ROA. 90% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS35937 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.
