As of 23rd October 2026, AS6300 (Fidium), an access network registered in the United States with ARIN, originates 73 IPv4 prefixes covering 285k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 1,012th-largest of the 79,663 networks we see originating IPv4, and the 265th-largest of 18,476 in the United States. It is seen behind 7 upstream networks, most often AS6461 (Zayo Bandwidth) and AS174 (Cogent Communications, LLC), and in front of 23 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 AS6300 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.
