As of 22nd October 2026, AS22213 (Salk Institute), a network registered in the United States with ARIN, originates 9 IPv4 prefixes covering 2.3k addresses. By IPv4 address space that makes it the 24,128th-largest of the 79,663 networks we see originating IPv4, and the 6,050th-largest of 18,476 in the United States. It is seen behind 1 upstream network, most often AS195 (San Diego Supercomputer Center). 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 AS22213 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.
