AS2495Kansas Research and Education Network

United StatesRegistryARIN

As of 12th November 2026, AS2495 (Kansas Research and Education Network), a network registered in the United States with ARIN, originates 3 IPv4 prefixes covering 131k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 1,974th-largest of the 80,772 networks we see originating IPv4, and the 627th-largest of 18,759 in the United States. It is seen behind 6 upstream networks, most often AS6461 (Zayo Bandwidth) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 13 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS2495 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.
