As of 29th September 2026, AS26388 (FIBERFI), a network registered in the United States with ARIN, originates 35 IPv4 prefixes covering 9k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 11,298th-largest of the 79,607 networks we see originating IPv4, and the 3,366th-largest of 18,442 in the United States. It is seen behind 2 upstream networks, most often AS174 (Cogent Communications, LLC) and AS15284 (Digital Service Consultants, Inc.). 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 AS26388 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.
