As of 23rd October 2026, AS24 (National Aeronautics and Space…), a network registered in the United States with ARIN, originates 1 IPv4 prefix covering 65.5k addresses. By IPv4 address space that makes it the 3,623rd-largest of the 79,663 networks we see originating IPv4, and the 1,274th-largest of 18,476 in the United States. It is seen behind 5 upstream networks, most often AS2152 (CENIC - CalREN) and AS297 (National Aeronautics and Space…), and in front of 1 downstream network. 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 AS24 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.
