United StatesRegistryARINTypeCarrier

As of 11th November 2026, AS32505 (Conterra), a transit carrier registered in the United States with ARIN, originates 181 IPv4 prefixes covering 83.7k addresses and 9 IPv6 prefixes. By IPv4 address space that makes it the 2,720th-largest of the 80,747 networks we see originating IPv4, and the 868th-largest of 18,752 in the United States. It is seen behind 8 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS174 (Cogent Communications, LLC), and in front of 68 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers, and 3 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS32505 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.
