United StatesRegistryARIN

As of 12th November 2026, AS6515 (DACS-IX), a network registered in the United States with ARIN, originates 5 IPv4 prefixes covering 1.3k addresses and 10 IPv6 prefixes. By IPv4 address space that makes it the 34,037th-largest of the 80,772 networks we see originating IPv4, and the 7,676th-largest of 18,759 in the United States. It is seen behind 12 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS6461 (Zayo Bandwidth), and in front of 6 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 93% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS6515 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.
