As of 11th November 2026, AS62600 (Arizona Board of Regents), a network registered in the United States with ARIN, originates 13 IPv4 prefixes covering 92.7k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,553rd-largest of the 80,747 networks we see originating IPv4, and the 824th-largest of 18,752 in the United States. It is seen behind 6 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS174 (Cogent Communications, LLC), and in front of 11 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 AS62600 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.
