As of 12th November 2026, AS17380 (Project Mutual Telephone Cooperative…), a network registered in the United States with ARIN, originates 33 IPv4 prefixes covering 40.7k addresses. By IPv4 address space that makes it the 4,951st-largest of the 80,772 networks we see originating IPv4, and the 1,731st-largest of 18,759 in the United States. It is seen behind 3 upstream networks, most often AS174 (Cogent Communications, LLC) and AS15305 (Syringa Networks, LLC), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 97% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS17380 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.
