AS85The Aerospace Corporation

United StatesRegistryARIN

As of 23rd October 2026, AS85 (The Aerospace Corporation), a network registered in the United States with ARIN, originates 15 IPv4 prefixes covering 76.3k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,875th-largest of the 79,652 networks we see originating IPv4, and the 923rd-largest of 18,475 in the United States. It is seen behind 2 upstream networks, most often AS226 (Los Nettos) and AS3356 (Lumen (Level 3)). 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 AS85 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.
