AS210Utah Education Network

United StatesRegistryARIN

As of 7th October 2026, AS210 (Utah Education Network), a network registered in the United States with ARIN, originates 29 IPv4 prefixes covering 1.4M addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 369th-largest of the 79,511 networks we see originating IPv4, and the 88th-largest of 18,429 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 7 downstream networks. 57% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS210 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.
