United StatesRegistryARINTypeCarrier

As of 22nd October 2026, AS600 (OARnet), a transit carrier registered in the United States with ARIN, originates 82 IPv4 prefixes covering 988k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 467th-largest of the 79,663 networks we see originating IPv4, and the 108th-largest of 18,476 in the United States. It is seen behind 7 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS3356 (Lumen (Level 3)), and in front of 56 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers, and 16 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS600 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.
