As of 26th September 2026, AS20355 (DartPoints Operating Company, LLC), a network registered in the United States with ARIN, originates 4 IPv4 prefixes covering 9.2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 10,999th-largest of the 79,516 networks we see originating IPv4, and the 3,308th-largest of 18,424 in the United States. It is seen behind 3 upstream networks, most often AS3257 (GTT Communications Inc.) and AS5009 (REV), and in front of 8 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS20355 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.
